Best impact wrench

An impact wrench is about matching the drive size and torque to the fasteners you actually work on.

Drive size

Smaller drives suit light automotive and assembly work. Larger drives are for heavy fasteners. Match the socket set you own or plan to buy.

Impact driver or impact wrench

An impact driver takes hex bits for screws. An impact wrench takes sockets for nuts and bolts. They are not interchangeable.

Check the real spec

Compare fastening and breakaway torque from the manufacturer, and check which battery the figure was measured with.
