- battery type – The most durable cordless impact wrench are those that have a lithium-ion battery. This type can be successfully and actively maintained for a long time without the need to replace it;
- maximum torque – the greater the torque, the cordless impact wrench with a lower torque works well for fastenings in passenger cars, with a higher torque – in transport and trucks;
- speed of rotation – determines the speed of the screw. In practice, this parameter is not decisive – usually, we do not use its maximum, so as not to break the screw;
- additional accessories – Make sure that the cordless impact wrench is immediately equipped with a set of different overlays that will expand the scope of its use.;
- weight – Pay attention to how difficult is the cordless impact wrench. It depends on whether the work will be comfortable or it will be inconvenient to hold it for even a short period;

Externally, the impact wrench uses a very similar gun. The equipment consists of a barrel, which, in turn, consists of various elements and systems. Also in it are motor, clamp and special springs.
The construction of this equipment directly depends on the principle of its operation. So, during start-up, the engine starts to generate energy. Energy enters the gear unit, which, in turn, controls the clamping device. If the tool is equipped with a second spring, you can also unscrew threaded connections. This is how the device works and you can be sure when reading cordless impact wrench reviews.
Today, you can buy a cordless impact wrench that can be equipped with 1/2, 3/4 or 1 “clamping cartridges. A cordless impact wrench with a 1/2” cartridge is used at home, 2 others – in car repair workshops, on construction sites, and in industry.
Thanks to the peculiarities of the design of the equipment, you will not feel vibrations during use. Cordless impact wrench does not require connection to a household electrical system or battery, it has a higher torque: all depends on the number of blades and dimensions of the turbine, the pressure pumped by the compressor. It is used, for example, for home repairs, car repairs and so on. Before you buy a cordless impact wrench, find out about its basic parameters: power, torque, and engine/turbine speed.
Capacity – this equipment depends directly on the equipment. For example, a professional impact cordless impact wrench can have a power up to 1.2 kW. Such power is enough, for example, to unscrew the bolts on the wheels of trucks. Torque – this indicator is the most important, cordless impact wrench should be selected very carefully, based on the value of this parameter. So, incorrectly selected torque can lead, for example, to the fact that the equipment will twist the wheel bolts more than necessary. As a result, you will break the tools when you have to change the wheel on the road. A too high value will break the thread.
The number of revolutions – A modern cordless impact wrench has a speed of up to 3000 revolutions per minute. Equipment with such an indicator of the number of revolutions, as a rule, applies to repair services cars and various industrial enterprises. For household use, we recommend buying a cordless impact wrench with a speed of 40 to 100 revolutions per minute. The impact cordless impact wrench, in comparison with the usual, has improved performance but also costs much more. Thanks to the installed power torque control system, you can easily customize the equipment for a specific task. The main parameter to be taken into consideration before buying a shock instrument is the pulse frequency, the average value of which is approximately 3000 beats/minute. Electronic torque control systems will allow you to more comfortable use of the equipment and guarantee the quality of the task.
Buy a non-impact instrument is recommended in those cases where it is planned to perform work with heavy and dimensional structures. After all, such a tool is distinguished by the increased moment of rotation. Cordless impact wrench has a reverse, so it is used both for the tightening of nuts.
Impulse cordless impact wrench works on the principle of shock-rotation. Thus, the rotational motions are converted into impulses and come to the square on which the end head is placed. Such a tool also has a reverse. The Cordless Impact Wrench Battery is a high-end stand-alone device and is suitable for use in places where there is no fixed electricity supply and no possibility to use a generator. A cordless impact wrench is great for screwdriver nuts and bolts (including rustproof), fastening parts made of metals, wood, plastic.
Due to the ergonomics and compactness, the cordless impact wrench is used in everyday life and for professional use. In particular, it is recommended to buy a cordless impact wrench for motorists.
You can also significantly expand the functionality of the device: you can install various additional devices on the cordless impact wrench. Before you buy a device, look at its body. So, the advantage should be given to the case of metal. Well, when the handle is equipped with a rubberized pad. It is worth noting that rubberized lining minimizes the negative impact, providing the comfort of work (no unnecessary vibrations).
The cordless impact wrench can be further equipped with various options, among which:
- electronic speed control system;
- system of instantaneous stopping of the rotation of the shaft (electronic brake);
- additional handle.
A cordless impact wrench can also be used with special straps that allow you to more conveniently store your equipment.
When choosing a non-impact wrench, determine the type of work to be done and pay attention to power, torque, and speed, which are the most important parameters when choosing this type of tool.
