What’s an Impact Wrench?

An impact wrench is a power tool. It’s a socket wrench that supplies a high torque output. It’s different from the old-fashioned socket wrench where you had to do all the work of twisting and turning yourself. This impact wrench does all the work for you.

Impact wrenches have a rotating mass where they store energy. This energy can come from rechargeable batteries, or with the help of compressed air. The energy is then swiftly transported to the outer shaft.

Types of Impact Wrenches

The way experts classify impact wrenches is by the power source used to operate them. The two most common power sources are electricity and compressed air.


Corded impact wrenches must be plugged into the wall. The motor is located at the rear end of the wrench.

While corded wrenches provide improved torque control and higher speeds, they’re prone to overheating.


These depend on batteries to power their rotating units. They’re portable and lightweight. You can take them anywhere, especially in tight, narrow workspaces.

Brushless motors provide an added boost to cordless wrenches. They provide more productivity, efficiency, and prevent the tool from overheating.

Even though they’re portable, the batteries tend to die rather quickly. Plus, they’re the most expensive out of all the types of impact wrenches.

Air Impact

Air impact wrenches, or pneumatic, are powered via compressed air tanks. They’re straightforward and easy to use. They rarely malfunction or overheat, which is great in terms of safety.

Their major drawback is that they constantly need a supply of compressed air. This is easy to set up in a repair shop. But it’s not so easy when you’re doing simple jobs at home. It’ll always be a burden to walk around while carrying it, even if you use a small tank size.
