Cordless screwdriver: which is better? Reviews. How to choose a cordless screwdriver, which firm is better? Which screwdriver is better: Bosch, Makita, Interskol?

To ensure that the work was carried out as efficiently as possible, it is necessary to use a good tool. Let's find out how to choose a cordless screwdriver , which firm is better, and what kind of devices are preferred by professionals.

Platform is an important detail

No, even the most important. The platform is one of the most important criteria by which it is recommended to select this hand tool. This parameter can be determined if the battery voltage is detected. Today, there are about 4 main platforms. Each brand that engages in the production of an electric or battery tool, works with any single platform.

To find a platform means to find a compromise between the real mass and the capacity of the device. You will understand which is better to choose a cordless screwdriver.

Available platforms

Thus, instruments operating at a voltage of 18 V, are even-average. The voltage value makes it possible to achieve a good torque of up to 100 Nm, and the weight will be quite light. This tension creates most models for professionals, as well as some representatives of the amateur group.

The 24-V platform is used primarily to create the highest quality and most expensive equipment. This is a powerful engine, less sensitivity to overload, reliability and increased working life. Screwdriver rechargeable which firm is better? Here everything depends on the needs and work to be done.

Models designed for 12 and 14 V are a lot of amateur devices.

Here, compactness and lightness have a much higher priority than high power, high performance characteristics, service life. It must be said that often on this strain, you can identify some series of tools for professionals from market leaders. If you plan to use this device frequently and seriously, then your choice is a professional cordless screwdriver. Which is better to choose from all available variety of models, depends on some requirements. But do not be too flattered. 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 into a solid wood 120-mm screw.

Accumulators

These assistant assistants and professionals can be powered by batteries such as Ni-Cd or Ni-Mh. Common lithium-ion batteries are also commonly used. The first two batteries are more common because of the low price, storage capacity in the discharged state, and also work at low temperatures.

Ni-Mh batteries are slowly discharged. This is noticeable if we compare them with a more capacious Ni-Cd.

But the price of such batteries is more expensive. But on charge-discharge cycles they are noticeably weaker. Up to 700 cycles are allowed here.

Screwdriver rechargeable - which is better? Reviews say that standard Li-ion batteries have virtually no drawbacks. Here we observe a short charging time, and there is also no loss of charge when idle. Among the advantages also can be allocated higher capacities, lack of memory, working hours. The prices also fully correspond to the high characteristics. Such a battery will cost from 3 to 8 thousand.

Reducer

To choose a cordless screwdriver (which is best for you), it's useful to know some important characteristics. So, one of the important indicators is the speed of revolutions. In terms of the number of revolutions, all devices can be divided into two classes - drills on batteries and a screwdriver directly for installation work. The speed of revolutions in screwdrivers is small - about 400-500 rev, but the torque is quite high.

Manufacturers recommend using them for spinning. However, modern mounting techniques provide not only the performance of fasteners, but also drilling.

Drill, fasten, thread

To activate the drilling mode, on many devices from respected brands there is a special flip-up frame. It switches the operating modes of the gearbox. The drilling speed doubles the drilling speed. Also, the torque will be reduced by half. Drilling is less common, but the presence of such a regime is one tool instead of two. There is also a three-speed cordless screwdriver, which is better at tapping with tapping. Here it is possible to get an even lower speed, and the torque will be simply huge.

Planetary gearboxes

In these devices, planetary-type reducers are used. Often in such designs, you can find three satellites. The driver is rigidly attached to the crown, it has a smaller gear. If the device is capable of delivering up to 25 Nm of torque, then the gear unit is predominantly plastic. At a torque of up to 50 Nm, manufacturers allow a plastic housing. If it is a powerful tool designed for professional use, the reducer consists only of metal parts. Choosing a cordless screwdriver, which is better - not difficult to guess. Metal parts have a much higher durability and a reliable service life.

Safety clutch

This system allows you to adjust the torque. Use the device in the same way as a torque wrench, it is not possible, and the scale is only conditional. However, if manufacturers indicate the data of the dependence of the forces on the position of the regulator, then this tool can be taken into account.

By its design this part is a ratchet in the outer gear of the reducer. It is additionally urged by an annular spring. One end of it is connected to the body of the device. The second is connected to the rotary handle of the cartridge. To choose a cordless screwdriver, which is better, reviews do not need to be excluded. So, users write about weak places - this wire rod and directly the spring itself. It is made of poor-quality materials and after a while of intensive use it loses its characteristics.

Ergonomics

The convenience of using a hand tool is more than simple comfort. Many manufacturers of these devices are constantly trying to constantly improve the performance of ergonomics. There are many different forms of housing, materials for lining. Many devices differ in the distribution of weight, the location of the controls. So, a cordless screwdriver, which is 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 convenient screwdriver 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 the handle angle too far back. Because of this, it is not always easy to use the tool. The masters become numb or unnecessarily overextended their palms, and a corn appears between the thumb and forefinger. Switch the direction of rotation with one hand, it has to be done quite often. Cordless screwdriver what is better? Feedback will help you decide, but it's best if you keep your choice in your own hands. Also, it is not superfluous to make sure that the selected instrument is perfectly balanced.

Choice for the specifics of the work

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

So, for those who collect furniture, more compact models will do. They are convenient because you can work even in the most inaccessible places, and effort and torque is enough for reliable and high-quality assembly. The drilling mode is practically not used here. So, for drilling a more powerful screwdriver battery is purchased. Which is better? "Makita" provides a large selection of professional tools at a very affordable price. Screwdrivers of this company have high characteristics and are very convenient.

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

In the works on special installation, power is important. Therefore, choose a cordless screwdriver, which is better for additional functions. Consumers want the device to replace both the puncher and the drill.
