With a compact size and relatively low weight (0.3 kg) the tool has a pretty decent torque of 2.8 Nm, which allows you to screw in rather long screws in materials of high hardness. The LED spotlight, reverser, and ability to quickly change tips make this cordless screwdriver one of the most popular tools for home and professional use. The elastomeric-coated rotary handle makes it very comfortable to hold, and allows you to work even in hard-to-reach places. Nickel-cadmium battery with a fairly high capacity makes the screwdriver fully self-contained. The exchangeable bits included in the set are coated with an anti-corrosion lubricant and are characterized by their better wear resistance.

Some explanations and symbols

Every screwdriver consists of a rod, handle and tip. Can be either one-piece or compound, with a variety of bit sets, greatly increasing the tool’s working range.

Screwdriver handles are most commonly made of plastic. They are easy to clean and very practical. To make the screwdriver more comfortable to use, many manufacturers make rubber inserts on the handle, which helps to avoid slipping.

Quality screwdriver rods are made of high-alloy steel and have a stainless coating. Rods, made of chrome vanadium alloy, are not afraid of corrosive liquids and oils. Shank hardness should be no less than 48 HRC (designation of hardness determined by Rockwell method).

Tip. the tip of a quality screwdriver is often magnetized, for better fixation of small fasteners. Oxidized tips last a very long time as evidenced by their dark color and roughness.

Screwdrivers are also cordless and reversible, impact, dielectric, and indicator screwdrivers. May be sold individually or in sets. From the variety of tools on the market today, we have selected the best ones based on feedback from real customers and professional users.

It is easy to get lost in the variety of screwdrivers.

Impact self-made screwdrivers

Many people wonder if it is possible to make an impact screwdriver with their own hands. You can, but it’s worth thinking about before you do it. The hammer screwdriver, or pressure screwdriver, is made from special alloy steel. It must be impact resistant, but it must not be brittle. Machining such steel at home is hardly possible, you need a special tool for that. In order to transmit the shock impulse to the rotary mechanism, the mating parts must have a certain curvature. They can only be machined on a milling machine.

In some designs, bevel gears are used for the torque transfer function. You need a self-centering chuck or something similar for interchangeable bits. Alas, you can’t make all these parts “at home”. You can make some kind of homemade impact screwdriver, using softer materials. But in this case there is a high probability that after several hits on such a device it will be destroyed and sent to scrap.

Without special materials and skills, you can probably only make a handle for a screwdriver with your own hands. Some models have a plastic handle as standard. It often cracks and craftsmen replace it with a self-made wooden handle.

This tool is an indispensable helper of a locksmith-repairman. It can be used not only for screws, bolts and self-drilling screws. By fixing a hex adapter in the chuck, you can use various sockets for unscrewing nuts as an accessory.

A rotary impact screwdriver can also be used for the reverse operation, that is, for tightening fasteners. If you do this, it will be impossible to unscrew such a connection with an ordinary hand tool.

Screwdriver reversible with a set of bits

Most manufacturers produce such screwdrivers in a set with a variety of bits.

In addition to the screwdriver itself, which can have any type of handle, such sets usually also include:

  • bit holder;
  • bits (for precise work the set includes similar bits of smaller size);
  • extensions (for precision work a flexible extension cord is needed);
  • adapters for socket heads;
  • sockets with different diameters.


This type of tool is needed when dismantling old structures, the fasteners of which are “welded” or covered with a layer of rust. This rating of screwdrivers by quality includes three of the best samples with straight and Phillips heads that can withstand the toughest loads.

Impact screwdriver technical parameters

Every manufacturer strives to make his product not only qualitative, but also multifunctional. The impact screwdriver, depending on the technical features and configuration, has the following characteristics:

  • reverser. A good tool is sure to have a reversible design. This function is not always needed, so on products from Soviet times, they are absent. The presence of reverser affects the cost of the tool, but is not always justified by the need
  • Material of production. Products of Soviet times were made of steel, and in this form went on sale. Modern models are rarely seen without a surface coating, which is polyurethane, rubber or polyethylene. The metal base coating not only provides extra protection to the tool, but also eliminates the possibility of slipping and electric shock when working with electrical devices
  • Handle. The role of the handle in an ordinary tool is to apply physical force. The impact screwdriver has a slightly different handle that is part of the impact-rotary mechanism, and is designed to hold the product during cutting operations

This is interesting! Every home handyman has encountered a situation where a fastener cannot be unscrewed. Usually such a situation is familiar to car owners, when the rusty bolt of the door hinge mount is not unscrewed. For such purposes, a special bit is put on the impact screwdriver and used to perform the corresponding actions.
