The screwdriver is a tool that each owner should be. What screwdriver is better to buy for work on the house - consider the rating of the best and the rules of the selection of this indispensable assistant in the economy.

First of all, it is not necessary to chase for the cheapest, even if the tool is needed only at times. The manufacturer and model must be chosen depending on the following technical characteristics of the intrusion: speed, power, operation mode, and other parameters. Next, we will present all the information about the choice of screwdrons and consider the most popular of them.

Modern screwdriver

A screwdriver is a universal device that is actively used in everyday life. The appointment of such a power tool is to twist and unscrew the screws, screws.

There are dozens of models of similar tools that are divided into several categories. Before choosing a screwdriver, the criteria and conditions under which it will be used should be used.

The price range of the described Power Tool category is wide, so everyone can choose a model for an alleged budget.

The choice is highly dependent on the operating conditions. For home use, some technical parameters are relevant. For professional use, more expensive and powerful versions with a removable battery will be required.

Selection of tools for home and work

To make the right choice and buy a suitable screwdriver, it is necessary to determine the selection criteria. They are not that much, and the process itself seems simple, but, then not to regret buying - it is better to clarify the nuances that can not be known to everyone.

The most important thing is to determine for yourself, with what frequency and intensity will be used tool. If it is needed, to twist a few self-tapping screws to twist the most fiscal model once a month. However, for more frequent use, it is necessary to choose more and more.

A common mistake is the choice of the cheapest model to use the tool in just a couple of days, but under large loads. For example, to collect metal structures (like a garage), or set fences in the country, the first cheap model is not suitable.

The first question that customers of such a device are specified in the food type. Today, models with a network cord are offered (the tool works only on the outlet of 220 V), as well as on a replacement battery.

Before choosing a screwdriver on the battery, it is necessary to determine under what conditions and for what purposes it will be used. The fact is that the battery power is limited, so the high-quality model of the screwdriver with a network cord can be more powerful.

On average, the battery charging is enough for 100-250 screwed screws or screws. With an increase in battery life, the device's power decreases, which increases the twisting time and the load on the motor increases.

The container of the battery itself is also limited. The manufacturer indicates that it is enough for several hundred cycles of charging and discharge, after which it will be necessary to purchase a separate component for a specific model.

The complexity may occur if the owner's screwdriver is long, and this version is no longer produced. Therefore, you will have to spend some time to find the desired battery, identical in power and fastening.

They have rechargeable screwdrivers and their advantages that are in the autonomy of work. Network models usually have a cord to one meter long. This is not enough even in order to connect the device to the nearest outlet, so you always have to use the extension.

If work is carried out outside the garage or at home, additional spending will be required. Also, a network tool is difficult to work at height (for example, if you are engaged in assembling frames, high furniture, designs, canopies, arbors, garages and the like).

Therefore, before choosing a battery screwdriver, you must determine how important you are important. After all, network power tools of this category can cost several times cheaper than options with a removable battery.

Network screwdrivers are more affordable. They differ in the same level of torque, regardless of the time of operation. The minimum rotation speed is 250-300 revolutions per minute. This is enough to drill holes in boards with a thickness of up to two centimeters and twist the screws in them.

To work with thickened material, you should select a more powerful model. Averaged value for heavy working conditions is 750-1300 revolutions per minute.

Specifications

To know what to choose a screwdriver, it is also necessary to own knowledge of the technical parameters of each category of power tools. Before you choose a battery screwdriver, you need to pay attention to the type of battery. From this will depend on the duration of the device from one charge and the overall service life of the battery.

The following types are distinguished: Ni-MH (nickel-metal-hydride), Ni-Cd (nickel-cadmium), as well as Li-ion and lithium polymer (Li-POL). In the first case, it can give a high current, but the resource of the device is less than that of other batteries. The devices with a Ni-CD type battery have a greater energy intensity.

Nickel batteries are used less often, since physical properties They are prone to discharge, if they do not enjoy several weeks. Lithium batteries are more practical, but they are not deprived of flaws. For example, in a strong cold, the battery resource is reduced by 30-50%. The optimal parameter for tank is 2 a * h.

Pay attention to this indicator when choosing to provide yourself with a stable operation of the device for several hours.

The description most often meets the indication of the mode of operation, as "unknown and reverse". This means that the screwdriver can only be used in the standard nozzle rotation mode in one or the opposite direction. The minimum power indicator is 400-800 W.

For professional use, it will be necessary from 1000 W to ensure stable and smooth operation even at high loads. Low values \u200b\u200bare relevant for battery screwdrivers that are intended for simple tasks.

Criterias of choice

Network screwdrivers are selected by power, by type of cartridge and the speed of rotation of the nozzle. In the first case, you need to select models with minimum power 600 W, as mentioned above.

It is also necessary to consider the parameter of the speed of rotation of the nozzle. What it is higher, the smaller and more stable drill or a screwdriver will enter the tree, metal. With low speed, the work of software and metal is hampered, and the risk of overheating of the motor is increasing. The diameter of the cartridge in most models is 10 millimeters, which is standard.

The list of characteristics occurs about the type of cartridge. Today, high-speed or hexaghed cartridges are highlighted. The first option is more practical in everyday use, since it will not require the use of a separate hex key to replace nozzles.

Independent or bimuft cartridge is delayed manually. The first option requires less effort - this design is more often installed on expensive screwdrivers.

The hex cartridge requires the clamp a bit by a separate key that enters the device kit. Additionally, such screwdrivers are always completed with bits with different tip, which can be changed by one hand, after which it is possible to tighten the connector with a small key.

When choosing, it is important to pay attention to the overall weight of the tool. Models with a battery weigh by 0.5-1 kilograms more network options, which can lead to inconveniences with long work.

If the screwdriver will weigh up to two kilograms, it will reduce the accuracy of its application and will speed up the onset of the physical fatigue of the operator.

Few notice such detail as the arrangement of the handle. Some models of the power tool have the standard form of a "gun", and other handle is shifted to the center to stabilize the center of gravity. The second option is more convenient for frequent use - the load is distributed and centered in the handle itself, which requires less effort.

Today's market presents a large number of models of screwdrivers for every taste and wallet. To accurately choose a tool for its purposes. It is necessary to familiarize yourself with the main advantages and disadvantages of specific options and characteristics on which the types are separated.

First of all, when choosing a power tool, it is necessary to clearly define the scope of its use. Often, the household segment of the power tool has a much smaller cost in contrast to professional.

Second a distinctive feature Home appliances are their characteristics: such a tool may not have all the functions of high-class models, not possess high power, productivity and hardening case, however, it is brilliantly suitable for everyday work in the house or in the workshop.

The amateur mini-screwdriver most often works with the help of batteries, which makes it mobile and practical.

Professional models are designed for long work in conditions of high loads. Such overall and heavy tools, as a rule, operate from the network, which ensures uninterrupted and long-term operation, provided that there is a stable access to the power supply.

Additional functions of screwdrivers

Manufacturers can add additional features for power tools. They do not affect the power or efficiency of work, however, if they are presented, the use of a screwdriver becomes more comfortable.

Among such functions, it is possible to highlight the presence of backlighting about the handle for illumination of the working area (simplifies the use of power tools in a dark place). The impulse mode of operation deserves attention, in which it is easier to work when druckching screws, self-drawing.

Network or accumulative

As mentioned above, electrical screwdrivers are divided into two large groups: working from the network and those that function with the help of batteries.

In order to stay at one of the options, you should clarify the difference between them:
1. batteries make devices more and harder, and for "networks" is characterized by lightness, but binding to the place of use;
2. network models are more often used for professional work, and rechargeable short-term use;
3. if there is a stable connection, network screwdrivers operate for a long time without overload and excessive heating, and the battery will have to change batteries or recharge;
4. the cord when working with a network device has the properties to be confused, with an autonomous model you can forget about such problems.

The popularity of rechargeable professional and household screwdrivers is due to ergonomic design, quality and independence. Due to high demand, it is worth staying on these models and consider the types of batteries used.

Before choosing a screwdriver for home, garage and cottages, it is worth deciding with the source of its power. Network models use a regular household network for this, and the devices on batteries are equipped with a removable battery. Each type has its pros and cons.

The rechargeable screwdriver is good with its autonomy. It is conditionally independent of the outlet and can be used at least in a pure field. This expands the scope of applying a similar tool. However, the battery imposes restrictions.

The first of them is a limited time of work. Usually charges enough for a hundred-other self-tapping screws, but in difficult conditions autonomy is reduced. The second minus is limited power (torque).

It may be insufficient for working with solid and durable materials. There are also positive exceptions, like a professional Makita DTD146Z, but they are not suiced.

Wired network screwdriver - a tool with a higher power and speed of rotation. It copes perfectly with the twisting of screws and self-tapping screws, can be used in drilling mode, and due to the absence of a heavy battery - less weighs. A permanent power source allows you to think about saving the charge.

However, far from the outlet, such a screwdriver will succeed except if there are long carrying or generator. There are also exceptions here, but unpleasant: the cheapest Chinese models are not more powerful than battery analogs, but it is also not autonomous. The minimum acceptable choice is something like the DE-850 Dnipro.

What to choose a screwdriver - network or rechargeable - depends on the needs and alleged operating conditions. If the tool is not used outside the house, apartments, garage and other premises - better network. It is cheaper with equal power, easier, and is ready to use anywhere with at any time.

Rechargeable screwdriver is optimal for use outside the premises, including outside settlements. At the same time, it is desirable to choose models with a capacious battery, not less than 2 a * h.

What to choose the type of battery

• Nickel Cadmium Batteries

The indisputable advantage of this type of batteries is low cost. Ni-CD batteries are most often used by manufacturers in creating budget lines of power tools. Another advantage is a five-year warranty, which exceeds the standard for 2 years.

• Nickel-metal hydrate batteries

They are distinguished by a high level of environmental friendliness and are increasingly used in the production of high-class wireless tools. The dimensions and small weight of the batteries make the tool itself much easier and more convenient. Perhaps the only drawback of NI-MN batteries is a high cost.

• Lithium-ion batteries

These batteries are considered the best for mobile power tools. They hold the charge for a long time, they are very quickly charged, and they also have no charge memory effect. The only lack of Li-Ion batteries is considered to be a high cost.

When choosing an effective screwdriver with a battery, you need to carefully treat its characteristics, because the cost of the battery is half the value of the entire instrument:
1. the total voltage in different batteries ranges from 10 to 24 V, the power of the device depends on it and affects the duration of work;
2. battery manufacturing material affects battery capacity;
3. loss of battery capacity due to charge memory effect.

The accumulator screwdriver, the price of which depends on the type of battery and other characteristics, important for high-quality performance of any complexity - the in-demand tool in each house.

Power and torque

The second thing you need to consider before choosing a screwdriver is its power and torque. Very often, sellers indicate power, but do not indicate the torque of the model and shut down the power in the battery tools.

With power, everything is sufficient simply: 600-800 W - more than enough for non-professional (home) applications, if not required and drill a lot. But torque - it is worth considering more.

Torque (measured in Newton meters - N * m) The screwdriver determines which force it can be applied when twisting the self-pressing. The higher this value, the more solid and durable materials will enter the screw. With a lack of torque, the transmission mechanism of the tool will drop, and the screw will be stuck halfway.

In order to twist small screws (up to 50 mm) into not very solid wood, quite any screwdriver. However, it is necessary to work with solid wood that the torque was at least about 15 N * m. For longer screws and self-tapping screws, 20-30 N * m are needed, and the model from 40 N * m and will cope with the twisting of the "acres" into the solid timber.

Rotational speed

For a domestic screwdriver, the speed of rotation is not fundamentally an important parameter. The tools are equipped with a downward gear mechanism that converts high speed on the motor shaft into low on the cartridge.

Pairs of hundreds of revolutions per minute is quite enough to screw, and the high speed of rotation is fraught with scorching the bits. This leads to both premature deposits of nozzles and licking the slot of the screw of the self-press.

Before choosing a screwdriver with drill functions, the turns still need to pay attention. When working with solid materials, there are few of them. 1000 rpm is a minimum suitable for and similar to hardness materials, and 3000 rpm do not interfere.

Type of cartridge

Another point to take into account to decide which chosen the screwdriver is the type of cartridge. The universal solution is a quick-sample cartridge, in which the bit is fixed by rotating the clamping ring.

It allows you to use not only bits, but also drills, heads for spinning nuts. You can also insert a nozzle mixer to mix the solution, a grinding brush "umbrella" into such a cartridge.

The hexagon cartridge under the bits is good because it reduces the mass of the instrument, and also allows you to quickly change the nozzles. They hold on it with a special retainer or magnet and extracted when applying a small effort. However, the drill in such a cartridge does not insert.

There are exceptions - these are models that are also completed with removable quick-inspection cartridge. They are most versatile, since they are easier to twist themselves, and for other purposes can be used.

Overview of popular brands

How to choose an accumulator screwdriver, what company is better? To simplify the final choice of the model, you must specify the most popular brands under the logos of which modern power tools are produced. From this partially depends the durability and cost, therefore the choice of a particular manufacturer should not be neglected.

Overview of popular models:
• Makita is a Japanese company that produces high-quality power tools (founded in 1915);
• Dnipro-M - Ukrainian manufacturer, who develops and manufactures the power tools in the available price segment (most of the models are produced in China);
• Bosch is a German company that does not require a separate presentation;
• VERTEX is a company that produces power tools in Taiwan;
• Forte is a certified Ukrainian power tool manufacturer.

conclusions

To immediately know what to buy a screwdriver for home or work, you need to explore the working conditions described above, as well as the tool selection factors. Next, an objective list of advantages and disadvantages of each type of device are compiled.

Advantages of models of power tools operating from the network:
• Preservation of rated power, regardless of work time;
• The ability to work unlimited time without interruptions to recharge;
• The lower cost of the power tool, in comparison with the versions with the battery.

Disadvantages of the screwdriver operating from the network:
1. The complexity of work at the height (heavily hold exactly the tool together with a long wire and extension);
2. It is impossible to work without an extension cord and socket 220 V (the working area is limited to several tens of meters from the outlet).

Based on the list of advantages and disadvantages, it is relevant to say that a network screwdriver is the optimal solution for an apartment or a private house. At the same time, it is necessary to stock extension to 5-20 meters extension to ensure freedom of movement with power tools in hand.

The average resource of such devices is not limited. According to users, on average, one model withstands 2-4 years of active operation.

Advantages of rechargeable screwdrivers:
• The possibility of remote work, regardless of the proximity of the outlet;
• The possibility of developing high nozzle revolutions.

Of the disadvantages, you can allocate limited operation time, limited battery capacity and weak power of cheap models.

If a device without a network wire is needed to work or at home, more urgently take quality, expensive versions of a battery screwdriver. This will reduce the time required for charging, and will provide stable power when working even with solid materials.

If you are an amateur to make, then you probably have a screwdriver in arsenal, the price and quality of which you are satisfied. If not, then you are of those who are just going to make a profitable purchase. Without this tool, it will not be possible when repairing or during construction work. To solve any household tasks, this equipment is perfect. However, it is initially necessary to decide on the main criteria for the choice, which will be discussed below. Some consumers before buying a particular product carefully study the reviews, because they are sometimes forced to make the right acquisition. If the choice is made correctly, then parts for the screwdriver will not be purchased during the entire period of operation.

Selection of a rotational speed model and torque

It is important before visiting the store well to explore the rating. The screwdriver can be selected on the basis of feedback from experienced masters. Specialists advise you to take into account the speed of rotation and torque. The latter parameter will determine what force the tool is attached when fastening fasteners. This characteristic also indicates to what power resists the load equipment.

If you want to choose a tool for solving homework, then the torque must vary in the range from 10 to 15 Newton meters. Professionals choose equipment with a torque, limited to 135 Newton meters. As a result, the wizard get the opportunity to work with solid materials. The engine shaft of such a device in one minute will be able to make 1,300 revolutions.

If we are talking about household models, you will have to be satisfied with 500 turns per minute. It is important before visiting the store to consider the rating. The screwdriver chosen by you on the basis of consumer recommendations will meet all requirements. Depending on the torque, it should be selected and the length of the fastener, as well as its diameter. If you compare the screwdriver with other electrical instruments, then select the ability to adjust the torque, for which the limiter is used. This supplement is represented by a ring that is after clamping cartridge. As soon as the Master will overcome the effort, after which the screw will no longer enter the wall, he will hear the characteristic rattling sound. Such a restriction will save the tool from the breakdown of the slot, the wear of the bits and deep consuming fastener into the surface.

Selection of the model depending on the power supply

There is a tool running from the network. The latter has an impressive mass, and you can work with them without removing away from electrical outlet. For lovers, not depend on the charge of the battery is invited to purchase an additional extension cord, whose metrarium will determine the range of use of the tool. Instruments with batteries weigh less, but you can work with them very limited time. Consumers choosing the accumulator screwdriver value autonomy. If it is often necessary to produce construction work in the field, the battery model will be more convenient.

Recruitment model selection

Consumers who choose comfort, and not a need to recharge the tool every half an hour, relate to the choice of batteries. The latter are three varieties, nickel-metal hydride batteries are protrude as the first, the second type is lithium-ionic, while the third is nickel-cadmium devices.

When it is worth choosing a screwdriver with a nickel-metal hydride battery

The power of the screwdrivers can be made from the Ni-MH battery. They become more common in recent times, as European models are equipped with them. They are environmentally friendly, low weight and minor sizes. Spare parts for the screwdriver can be purchased in the service workshop, like the battery. As the main advantage of the above-mentioned batteries, there is no memory effect, but there are also disadvantages. It is important to remember that such batteries do not like current overloads and exposure to low temperatures. The device that feeds from this battery will cost more, but the number of recharging in this case is 1500. If you need a long storage of the battery, it should be charged, and it is unacceptable to leave in the discharged state.

When it is worth choosing a screwdriver with a nickel-cadmium charger element

If you want to choose a good accumulator screwdriver, it is important to remember that the aforementioned battery is more toxic, but it is two times more recharging. The cost of tools operating on the basis of nickel-cadmium elements are slightly lower, the frosts of the battery of this type are not afraid at all. That is why for Russian conditions they are suitable as it is impossible. But these batteries are characterized by a strong self-discharge and memory effect, which can be called significant disadvantages.

When it is worth choosing a lithium-ion battery

That consumer who wants to choose a high-quality tool, reads rating. In this case, the screwdriver will be able to purchase at an affordable cost and with outstanding characteristics. For example, it is not so often installed in the screwdrivers. They differ in the maximum sensitivity to cold, and their power is low. The master can count on 3000 recharging, there is no memory effect for such a battery. Do not be surprised that the equipment will have a high cost, which is not compensated by even an impressive capacity. Self-discharge such batteries are almost not subject to, which is why they are convenient to use at home when to use the tool often.

Rating popular models

Professionals and lovers are increasingly today choose Makita brand goods. Screwdrivers are no exception. As an excellent example, the DDF343SHE model can be distinguished, the cost of which is 8900 rubles. The tool is equipped with a quick-instepted cartridge, as well as a drill function. The master will be able to work in one of two speeds. At idle the equipment can issue 1,300 revolutions per minute. The torque of the model is 36 N · m. Choosing a screwdriver whose price should be available, you can prefer Hyundai, among its models it is worth using A1220LI, the price of which is 5,500 rubles. You can work in one mode - drills, but use one of two speeds. The maximum number of speeds at idle is 1100 per minute. Maximum torque is equivalent to 28 N · m.

Combination of good quality and affordable cost

Specialists advise to consider the rating. The screwdriver chosen by you will have the characteristics that are necessary. In the market of relevant goods, you can find the model Hammerflex ACD182. Pay for it is 4500 rubles. The device is supplied with a quick-release cartridge, and you can work in one of 2 modes, namely drilling and wrapping of screws. The maximum speed of idle speed has 1200 per minute. This accumulator screwdriver has the most torque within 22 N · m.

For today, the screwdriver (Roverter) is one of those tools, without which it is impossible to imagine not only a professional builder, but also a common man planning to make repairs in her home or fold their independently acquired furniture.

Before you purchase a screwdriver, you need to determine what kind of objectives it will be used.

Since the construction equipment market is represented by a large number of models with different characteristics to acquire a good screwdriver, you need to understand this equipment. Therefore, it will be further reviewed how to choose a screwdriver for home.

Rovertere is a manual power tool, which is used to twist the bolts, screws and self-tapping screws, as well as for drilling small holes in wooden products. The main difference of such a device from the drill is the presence of a special mechanism that protects the slot of the screw from an excessive load, which can lead to the destruction of the product.

Device screwdriver: 1. Fastening node. 2. Effort regulator. 3. Lever change direction. 4. Battery. 5. Charger.

At different manufacturers, the layout of this equipment may differ slightly, but the principle of operation and main nodes are the same for all models:

• power Supply;
• electrical engine;
• control system;
• gearbox;
• safety mechanism;
• chuck;
• case.

To perform the same tasks that you stand in front of the screw, you can use the usual drill. However, as practice shows, it is not much easier and safer to apply not a universal tool, but a special.

It is very convenient to use a screwdriver for facing works, assembling furniture, installation of windows, doors, etc. As soon as the screw will be twisted until it stops, the protective mechanism will work and rotational movements will stop entering the cartridge. In this case, specific clicks in the protective mechanism will be heard. Such a device allows you to save the slots of the screw and prevent wear of the nozzle. In different models of the instrument, use from 5 to 22 stages of the safety mechanism.

Professional or household tool?

Before choosing a good screwdriver, it is necessary to determine the scope of the work that they will be performed. To perform small and short-term work, a household option is perfectly suitable, which will have less power and, accordingly, a smaller value from its professional analogues. Household screws are well suited for performing simple construction and repair operations:

• removing and screwing fasteners;
• minting dowels and anchors;
• drilling wooden, metal and other surfaces.

Professional models are used for conducting capacitive and complex construction and repair work. They are designed for long-term and continuous use, have relatively large power, and only high-quality materials are applied in their manufacture. Therefore, the price of such equipment will be much higher.

In everyday life, screwdrivers showing themselves 10-15 nm torque. The professional tool is equipped with a torque of up to 120-130 nm. In this case, the rotational speed can reach 1200-1300 rpm, while in household appliances It is enough 350-450 rpm. If you want to carry out small volume and complexity of work, then the screwdriver is quite suitable for the house.

Rechargeable or network screwdriver?

The screwdrivers can be powered from both the source of the AC (stationary network) and the rechargeable battery. Type 1 tool has 2 disadvantages: it is heavy and has a limited area of \u200b\u200buse. Battery equipment has a smaller weight and significantly greater mobility. They are comfortable to work on both the street and in the building. In this instrument there is no wire that constantly interfered when working.

If the screwdrity is necessary for daily work, then your choice should be stopped on a professional instrument.

There are several types of batteries, so choose a good accumulator screwdriver is not so easy. Batteries for mobile screws are divided into 3 types:

• lithium-ion (Li-Ion);
• nickel-cadmium (Ni-CD);
• nickel-metal hydride (Ni-MH).

Each type has its own strengths and weaknesses. The batteries of the 2nd species are somewhat similar to each other. On average, they withstand about 1000 and 500 cycles of charge-discharge, respectively. They are not afraid of low temperatures, but have a memory effect when the battery capacity decreases due to the fact that it has not been discharged or fully charged. Therefore, before charging, they must be completely discharged.

Lithium-ion batteries are deprived of this shortage, besides, they are considered more environmentally friendly. But they are prohibited by them in low temperatures, as this will lead to their failure. Choosing a screwdriver, you should pay attention to the presence of a replaceable battery.

Selecting a device with 2 batteries is a good and correct solution, since an additional battery eliminates downtime.

If you understand the advantages and disadvantages of each of the types of surnippers and it is difficult for you to make a choice in favor of a particular option, you can purchase a combined type that can work both from the network and from the battery.

The main characteristics of the screwdrity

If the work is carried out by a screwdriver at a stationary workplace, it is better to purchase an electric tool, as it does not require recharging and its power is higher than that of a battery screwdriver.

If you contact a consultant in a construction store with the words "help choose a screwdriver", then it should be understood that they are more interested in selling more expensive goods than in helping the buyer. If you do not understand the screwdrivers, get ready for such a purchase a large amount.

So that this situation does not happen, you first need to decide what kind of work you take this equipment:

• to remove and screw the screws, screws and other fasteners;
• for drilling wood of soft or solid rocks;
• for drilling or cutting threads in metal;
• to tighten or remove dowels and anchors when conducting mounting work.

Deciding with the appointment, you can proceed to. At the same time, its main parameters should be taken into account:

• maximum torque;
• the number of revolutions;
• modes of operation;
• type of cartridge.

The maximum torque is one of the main characteristics of any screw. It determines how the maximum diameter of the screw can be spinning into wood, metal and another building material.

If you are engaged in, for example, assembling furniture, then in this case it is better to buy a battery screwdriver.

In most cases, 10-12 Nm of torque is quite enough for home use. With such a power, you can easily twist most of the screws with a diameter of up to 4 mm to a depth of 90 mm both in the wood and metal. Such a tool can also drill holes in a tree with a diameter of about 12 mm, and in the metal - up to 8 mm.

If the screwdriver is used to overlap the roof of your home, then in this case it will be necessary to work with roofing self-stakes for which it is desirable to use a tool with a power of at least 20 nm.

The maximum number of revolutions determines the quality of work. For example, for screwing the screws, it is quite enough and 500 rpm, and for drilling, this value should be increased to 1200 rpm.

Various tool modes allow it to perform various functions. Very often, the screw is used as a drill. To do this, it should be able to work in simple or shock drilling mode. To carry out work on discount, the device must be equipped with a perforation function. Roverts for home can have up to 5 modes of operation, while professional - more than 20.

Cartridges for screwdrivers are 2 species: open-time and key. For the 2nd version, you need a special toothed key. If a quick-release mechanism is used, then in this case everything is much easier: you can easily insert it into it, and the bit holder.

The key cartridge may have 1 or 2 couplings. In the first case, the product is additionally equipped with a shaft lock mechanism when replacing one nozzle to another. If the coupling 2, then instead of blocking the cartridge holds 1 coupling, and the 2nd it claps it.

Additional functions of screwdrivers

Modern equipment has a number of additional functions that allow you to significantly simplify its operation. These features include:

Very important for the operation of the screwdriver, the speed of rotation is very important, since the more turns per minute performs the tool, the smaller the load on the engine.

1. The shock mechanism is a fairly useful feature that allows you to drill holes in the stone and brick.
2. The pulse increase in torque is useful for easier drowning fasteners into the material, when unscrewing the jammed self-pressing or a bera.
3. The backlight is a relevant addition when working in hard to reach places or in places with poor lighting. The most successful option is to place the light source over the battery pack.
4. An important function of the device is the ability to control the speed of rotation. Almost all modern models are equipped with such a function. With it, you can independently set the necessary speed of rotation of the drill, which allows you to better perform the tasks.

Ergonomic tool

An important point when choosing a hand tool is a form, arrangement of the handle and controls. The greatest distribution has screws with a pistol type handle. In this case it is very important to determine the center of gravity. Therefore, before buying, you need to take a tool in your hands and understand how quickly the feeling of fatigue arises. If in a few minutes you will feel discomfort, then it is better to choose another model.

There are models with 2 handles. They are more convenient when you need to drill a hole. Many building stores have special test stands. If they are presented, you can take a few species of the tool you like and produce a test drilling that will help you choose the best option for you.

Selection of tools by manufacturer

The quality of any construction equipment directly depends on the manufacturer's company. Each company ranks 1-2 segments in the construction tools market both at cost and according to the characteristics.

To work at home, you can pay attention to the tool of such famous manufacturerslike Hitashi, Hummer or Bosch. The equipment of these companies is characterized by good performance, high reliability, modern design and great availability of additional features. Trademarks Dewait and Makita more specialize in professional equipment, although they produce riflerts for domestic use.

But buying a screwdriver only because of the brand - means overpaying to ¼ of the stated value, since in this case, in addition to the functional features of the device, you will also pay for the name. In most models of well-known world brands, many additional functions are also built-in, which you can never even use at home.

Comparing all the characteristics of the screwdriver with their requests, appreciating its design and ergonomics, you can make the right choice and not disappointed in it during work.

In order for the work to be made as high quality, it is necessary to use a good tool. Let's find out, rechargeable, which firm is better, and what kind of devices prefer professionals.

Platform - an important detail

No, even the most important. The platform is one of the most important criteria by which this manual tool is recommended. This parameter can be found if you find out the battery voltage. Today there are about 4 major platforms. Each brand that is engaged in the production of electric or works with any single platform.

Pick up the platform is to find a compromise between the real mass and the power of the device. You will understand what better to choose the accumulator screwdriver.

Available platforms

Thus, the tools operating on the voltage of 18 V are even average. The magnitude of the voltage allows you to achieve a good torque to 100 nm, and the weight will be quite easy. At this tension, most models are created for professionals, as well as some representatives of the amateur group.

The 24-to the platform is used mainly to create the most high-quality and most expensive equipment. This is a powerful engine, less sensitivity to overload, reliability and an enlarged working resource. What company is better? It all depends on the needs and work that will have to be performed.

Models designed for 12 and 14 V are many amateur devices.

Here compactness and ease have a much greater priority than high power, high performance characteristics, resource of work. It must be said that often on this tension can be distinguished by some series of tools for professionals from market leaders. If you plan often and seriously use this device, then your choice is a professional accumulator screwdriver. What better to choose from the entire available manifold of models depends on some requirements. But you should not too deception. Such "bison", as "Bosch" or "Makita", position their devices as a technique for professionals, but any representative on this platform will not be able to twist 120-mm screws into dense wood.

Batteries

These helpers lovers and professionals can eat from Ni-CD or Ni-MH batteries. Ordinary lithium-ion batteries are also often used. The first two batteries are distributed even more due to low prices, storage capabilities in the discharged state, as well as work at low temperatures.

Ni-Mh batteries slowly discharged. This is noticeable if you compare them with more capacious Ni-CDs.

But the price of such batteries is more expensive. But in the cycles of the charge-discharge, they are noticeably weaker. It is allowed to 700 cycles.

Rechargeable screwdriver - what better? Reviews It is said that the standard Li-Ion batteries practically do not have drawbacks. Here we are seeing a short charge time, there is also no charge loss with simple. Among the advantages can also be allocated more high tanks, lack of memory, work time. Prices also fully comply with high characteristics. Such a battery will cost 3 to 8 thousand.

Reducer

To select a screwdriver battery (which is best suited to you), it is useful to know some important characteristics. So, one of the important indicators is the frequency of revolutions. By the number of revolutions, all devices can be divided into two classes - drills on batteries and a screwdriver directly for installation work. The frequencies of revolutions in the screwdrivers are small - about 400-500 o, but the torque is quite high.

Drill, krepim, cut the thread

To activate drilling mode, on many devices from respected brands there is a special re-frame. It switches the modes of operation of the gearbox. On drilling mode doubles the speed of rotation. Also twice the torque will decrease. Drilling use less frequently, however, the presence of such a mode is one tool instead of two. There is a three-speed accumulator screwdriver, which is better coping with taps. It is possible to get an even lower speed of rotation, and the torque will be just huge.

Planetary gearboxes

These devices use planetary type gearboxes. Often in such structures you can detect three satellites. She drove hard to the crown, it has a smaller transfer. If the device is able to produce up to 25 nm of torque, then the gearbox is predominantly plastic. With a torque of up to 50 nm, manufacturers admit a plastic case. If this is a powerful tool designed for professional use, the gearbox consists only of metal parts. Choosing an accumulator screwdriver, what is better - it is not difficult to guess. Metal parts have much higher durability and confident work resource.

Safety clutch

This system allows you to adjust torque. To use the device in the same way as it is not possible, but the scale is only conditional. However, if manufacturers indicate these depending on the regulator's position, then this tool can be taken into account.

By its design, this item is a ratchet in the outer gear gear. It is additionally pressed by an annular spring. One end is connected to the instrument housing. The second is connected to the spinning handle in the cartridge. To select a screwdriver rechargeable, what better, reviews do not need to be excluded. So, users write about weak places - it is a wire traction and the springs itself. It is made of low-quality materials and after some time intensive use it loses its characteristics.

Ergonomics

Ease of use of a manual tool - it is more than simple comfort. Many manufacturers of these devices are constantly trying to constantly improve ergonomics. There are many different shapes of the case, materials for lining. Many devices vary by weight distribution, the location of the controls. So, the screwdriver is rechargeable, what better, you need to choose the hand of the master and the type of work that you have to perform. It is best to choose a screwdriver convenient in every sense, even if you have to pay for it with other characteristics.

One of the important ergonomic parameters is the angle between the axis of the handle and the axis of the motor. Designers, creating, in their opinion, comfortable equipment, sometimes make too much angle of tilt handle back. Because of this, it is not always possible to use the tool. The masters are registered or overwhelmed with palms, and the corn between the big and index finger appears. Switching the side of rotation is needed by one hand, it has to do quite often. which is better? Reviews will help you decide but best if you yourself hold your choice in own hands. Also, it will not be superfluous in excellent balancing the selected tool.

Choice under the specific work

It may seem that the screwdriver is a universal tool. In fact this is not true.

So, for those who collect furniture, more compact models are suitable. They are convenient to work even in the most hard-to-reach places, and the effort and torque is enough for reliable and high-quality assembly. Drilling mode here is practically not used. So, a more powerful accumulator is acquired for drilling. Which is better? Makita provides a large selection of professional tools in a very affordable price. The screwdrivers of this company have high characteristics and are very convenient.

Also, these tools are used for mounting plasterboard structures. Here manufacturers offer two-speed models with capacious battery. For this type of work, the weight of the instrument is very critical. For work on the ceiling, models with one speed without a cartridge based on Canggi are suitable.

In terms of special installation, power is important. Therefore, the accumulator screwdriver is chosen, which is better than additional functions. Consumers want the device to replace both the perforator, and drill.

Brands and models

We reviewed the design, important criteria for choosing these tools. Now let's analyze the most popular models from all that is offered today on the market.

"Interskol"

When choosing such a tool, like a rehabative screwdriver (which is better), "Interskol" is ready to offer several limies of devices. These are screwdrivers for professionals and amateur-level devices for home.

The professional ruler is distinguished by the presence of two velocities, a capacious battery, a high torque. Nickel-cadmium batteries allow the device for a very long time to work offline. Torque in various models can reach 30 nm. Devices are durable, practical and infinitely comfortable. Lightweight models will make work with them more pleasant. "Interskol" is a decent accumulator screwdriver. What better - reviews will help with the choice. In general, people talk about the technique of this manufacturer very positively.

"Bosch"

The first model on our list is an excellent purchase for home. It is located in the green, non-professional line of the entire instrument from Bosch.

German or Russian accumulator screwdriver - What is better? Reviews of the first are very good. The parameters of this device are able to cover all needs. homemade Masters And even may give odds to some professional techniques. Bosch PSR 1200 is, first of all, compact sizes. Then the strength characteristics are thrown into the eyes. The battery is able to give 12 volts, and the force is 15 nm. In addition to sizes and strength, this is a rather functional device. It is possible to adjust torque, block the device from self-inclusion. Reverse makes working with the device and is very pleasant at all. If you are looking for an accumulator screwdriver, what is better for the house, then Bosch PSR 1200 is a great choice.

Also on the market is a professional tool. This is a blue product line.

The Bosch GSR 18V \u200b\u200bmodel is a dream of those who deal with furniture, namely, its assembly and disassembly professionally. This is a reliable and powerful German-made screwdriver. It is ideal for where the space is limited. In addition to other advantages, this device has a capacious battery. The powerful planetary gearbox in this model is able to produce up to 67 nm of torque. If you choose the accumulator screwdriver, what better, Bosch GSR 18V \u200b\u200bis a choice of professionals.

Bosch GSR 1440 is a professional model for two speeds from the blue line of products.

The advantage of the model is its price. The planetary gearbox allows you to create a 30 km effort. The overload protection system allows you to increase the durability of work.

So you learned how to choose a screwdriver battery. What firm is better? Each company offers several decent linecas. Choose your model.

In this article, we would like to touch on the topic of choosing a screwdriver, more details to disassemble their types and, of course, specificationswhich is worth paying attention to when buying this type of instrument, to expand to answer the question, which has recently arises more and more often, namely how to choose a screwdriver for home, cottages or work.

Scope of applying screwdriver

Direct purpose:

• twisting / unscrewing self-tapping screws, screws, bolts and other fasteners
• drilling of holes in wood, metal and brick

"People's" Application:

• stirring construction mixtures and paints
• drilling of holes for winter treated fishing (video)

Types of screwdrivers:

The market presents a huge number of screwdrivers, various parameters and manufacturers. They are divided into professional and domestic depending on the nutrient element, the size of the cartridge, power, a number of additional functions, a set of delivery and prices. This division is, however, is inherent in almost any tool.

To begin with, we will analyze division by the nutritional element. You can select two types: rechargeable (Li-ion, Ni-CD, Ni-MH) and electric, about each of them. We will talk more about.

Li-ion batteries

The most modern and most common, today, the type of batteries, not only in the screwdrivers, but also in many other tools (as well as in the portable devices that we all use you). Modern Li-Ion batteries are calculated for three thousand cycles charge-discharge. The battery has low weight and quickly charged, and there is also no memory to charge.

The main disadvantages are: the shelf life of the battery, which is three years, the need for permanent use, to obtain the maximum return and considerable cost.

Tip: The batteries of this type are intended for permanent use, and therefore it is advisable to take them not for one-time jobs to maximize the possibilities! It is also worth noting that Li-Ion batteries are not very desirable to recharge and discharge completely, a stable discharge up to 15% and the charge up to 90% will significantly extend the life of the battery. Three cycles charge-discharge will allow calibrate battery capacity to maximum.

Ni-CD Batteries

It appeared on the market for a long time, they find use in many tools, not only in the screwdrivers. Calculated for one and a half thousand cycles charge-discharge. The shelf life of such batteries is five years, also presents the possibility of working in the cold, at temperatures up to -15 degrees and is very important for a regular buyer, the lowest price of all types of batteries.

The negative moments of this type of batteries is quite long, in time, charging process (constitutes an hour at best), the availability of memory to the charge and the considerable weight of the battery.

Tip: Since the batteries of this type have memory to charge, you should take the rule to fully charge and discharge them, thereby not reducing their service life. A complete charge will take over the charger, and the full discharge can be achieved, for example, with a flashlight, which is very often found in the delivery of the screwdrivers with Ni-CD batteries. If there is no flashlight, you can pull the button with the usual rubber band and after some time the screwdriver is discharged itself. Store this type of batteries is recommended discharged.

Ni-MH batteries

In essence, there is a cross between Li-Ion and Ni-CD batteries. They are found in the screwdrivers much less often than the above-described types of batteries. The number of cycles charge-discharge varies about a thousand. It is practically no memory to charge, and has a minimal self-discharge among all types of batteries. Of the minuses it is impossible not to mark weight.

Tip: This type of batteries is almost spilled from the effect of memory, but still, before using a screwdriver, after long-term storage, it is worth discharge, and then charge again for further use. For long-term storage, the batteries of this type should be left fully charged.

All batteries differ in the tank and battery voltage.

Capacity is measured in amperes multiplied for an hour (A * h). The greater this indicator, the greater the battery is capable of carrying the charge, respectively, the larger work will be performed on a fully charged battery.

The battery voltage is measured in (volts). This indicator depends the power that can be obtained from the screwdriver operating on these batteries. Simply put, the battery voltage directly affects the maximum possible indicators of the soft and cruel torque, which we will talk about below.

Network screwdrivers

Very similar to a drill (do not miss the article ""), the main difference is the presence of torque adjustment. Models of the screwdrivers of this type are presented only by several manufacturers of the household tool. Eminent manufacturers make focus on professional screwdrivers for plasterboard work, the cartridge of which begins to rotate the bits only after "drowning" it into the material.

Network screwdrivers are suitable for one-time work on home or for professional use in repair and construction. Based on the situation, the lack of need for charging can be considered a plus. Restrictions created by the need to have an electrical network, low mobility and firing wires, definitely, the main disadvantages of this tool.

Cartridges and gearboxes

The screwdrivers are like a quick-sample three-tech cartridge (the cutting range of the equipment from 0.5 to 13 mm) and with a hexed seat under the snap with a 1/4 inches shank. The quick-mode cartridge is more practical and allows you to use any suitable for a diameter, snap. Of course, the larger the diameter of the cartridge, the more universally the screwdriver.

The hexagon cartridge is convenient if you need a frequent change of snap and when working in hard-to-reach places. For drilling such a screwdriver, it is necessary to use drills with a hexagon shank. It is possible to install an ordinary cartridge with a hex shank.

Rotation from the engine to the cartridge is transmitted by gearbox. Gears inside the gearbox can be made of metal or plastic. Metal gears are most characteristic of powerful professional models of screwdrivers.

Power screwdriver

Reflect two parameters measured in Nm (Newtonometer), this is a soft and hard torque:

• The soft torque is an indicator of the maximum screwdriver force in the twisting / unscrewing plan, the speed of rotation in this mode in most screwdrivers varies from 0 to 350 revolutions per minute.
• The hard torque in turn reflects the maximum force in drilling mode, in this case the rotational speed is usually calculated from 0 to 1000 or more revolutions per minute.

The more these parameters, the more powerful, more productive and more practical screwdriver. For example, a screwdriver with a torque from 25 to 30 nm is easily tightened into the tree Self-up to 70 mm long. To twist the screws from 70 to 100 mm, a torque from 40 nm will be required. To twist longer self-tapping screws, a pre-severity of the hole is required.

Important! This example is not universal, since the screws and materials used are different in quality and density.

Additional features of some screwdrivers:

The presence of a shock mechanism, no doubt, is a fairly useful feature, especially when working with end heads or when drilling holes in brick and stone.

The presence of a pulse, periodically increased torque, is useful for easier drowning fasteners into the material, when unscrewed the jammed self-pressing or even a drill, if the perforator does not cope. Especially useful when there is no possibility to continue to close the screwdriver tightly.

The presence of 3 speeds will allow to fully replace the network drill at home, since the speed of rotation of the cartridge in this mode can be more than 3000 revolutions per minute, and the first speed will be given a decent torque.

The presence of backlight is very relevant when working in hard-to-reach places or with poor, or even there is no lighting. The most successful version of the backlight over the battery pack, there are models with illumination located above the launcher, which is less efficient in most cases.

Summing up under all described above, I would like to note that it is impossible to advise the universal screwdriver for all, because many components of the choice depend on your goals and tasks that you are going to carry out this tool, but finally, I will still share my opinion about the choice On some examples:

- House / cottage screwdriver: For the most part there will be a network version, due to availability, low weight and lack of need for special mobility. If you consider the battery versions, then you cost to pay attention to Ni-CD and Ni-MH, if it is planned to work not often, so you will save money and get a longer battery life.

In cases where the frequent use is planned, requiring the continuity of the workflow, without any doubt, the choice of Li-Ion batteries justifies itself 100%. Why do I not advise you to take more modern batteries for rare work? Everything is very simple, they are more expensive and designed for stable use, it's not necessary to forget that the term of their suitability is less than 2 years less, and therefore, there will be much more missed opportunities in this case.

For the home needs of the maximum torque in 25-35 nm, it will be quite enough, of course, you can take more powerful, it all depends on your desire and financial opportunities. Battery capacity is not so important for periodic use at home, because 1.5-2 Ah will be just right.

- Screwdriver for professional use: When working in hard-to-reach places it is logical to choose a more compact model. Features of frequent and long continuing use in many cases will be justified to purchase a Li-ion screwdriver with a maximum torque of 40 nm and higher, depending on the type of materials with which it remains in the future.

Li-Ion batteries, in this case, are relevant due to the continuity of the workflow provided by rapidly charging batteries, as well as they are simply lighter, which matters for your hand with long-term use.

The choice of additional possibilities of the screwdriver directly depends on your needs. Try to clearly define for what kind of needs you will use it, decide on the budget. Not in the last place and the presence of other tools, like a drill or a perforator, with rare use these moments will allow you to cut off unnecessary functions and allocate clearly necessary.

In conclusion I would like to note that the screwdriver market is saturated with various variations and choose exactly what will suit you, will not be great difficulties. We hope we managed to help you decide on the choice of a screwdriver. We wish you a maximum return from the tool and more positive emotions!
