Suggestions for choice

Purpose.Start your search for a cordless impact wrench by setting goals for the tool. The optimal torque, spindle speed, chuck type and tooling set will depend on it.

Impact feature.Cordless wrenches use impact or nonimpact rotation mechanisms.

1. Non-impact mechanisms look preferable for tightening/unscrewing small hardware, assembly/disassembly of light structures.
2. Impact or pulse models allow you to perform maintenance on cars, unscrew oxidized bolts, nuts or self-tapping screws, professionally do construction work.

Torque. One of the main characteristics of a cordless impact wrench is its torque. It can range from 100 to 700 Newton-meters (N-m).

1. To work with self-tapping screws or small threaded fasteners, capacity of 100-300 N-m is enough.
2. For reliable tightening of wheel bolts or nuts, it is better to choose a more powerful model (400-700 Nm). But as the power goes up, so does the weight.

Pulse frequency. One more technical parameter the potential customer should pay attention to when choosing a wrench. This is the pulse (impact) frequency per minute. In some cases, it compensates for the lack of power of the machine.

1. Professional impact drivers are limited to 2,700-3,200 beats/min.
2. Household models with low-powered motors demonstrate the maximum number of blows at 3500-4000 beats per minute.

Chuck type. Since impact wrenches can work with various types of accessories, it is important to select the most convenient and reliable chuck.

1. Most models are equipped with 1/2″ square chucks. It will hold sockets securely.
2. The most powerful units may have a 3/4 or 1 inch shank.
3. And for work with self-tapping screws a chuck under bits looks optimum.

Additional options. Manufacturers equip their products with a number of modern features for safe and comfortable operation.

1. Backlit work area helps you tighten/unscrew metal fasteners in poorly lit areas.
2. The battery charging indicator visually tells us how much more you can work without recharging.
3. Electronic overload protection comes in handy for professionals who keep the wrench in their hands throughout the entire work shift.
