Cordless impact wrenches tighten and loosen nuts and bolts with strong rotational blows. Mechanics, tire shops, steel erectors, plant maintenance teams and heavy equipment crews use them on wheels, machinery, structural bolts and anchor bolts.
How to choose a cordless impact wrench
- Torque: compact wrenches around 200Nm to 400Nm suit cars, motorcycles and assembly. 650Nm to 1000Nm models handle trucks and machinery. The Bosch GDS 18V-1600 and Makita TW001G reach 1600Nm and 1800Nm for heavy equipment.
- Drive size: 1/2" drive is the most common. 3/4" drive models such as the Bosch GDS 18V-1050 H take larger sockets.
- 2-in-1 models: the Bosch GDX series takes both sockets and 1/4" hex bits, so it also works as an impact driver.
- Battery platform: choose a wrench that uses batteries you already own.

Use impact-rated sockets
Standard chrome sockets can crack under impact. Use impact sockets or a deep impact socket set, and check final torque with a torque wrench on wheel nuts. For shops with a compressor, compare pneumatic impact wrenches.
