Overview

The AP-001 is a cordless impact wrench with a 3/8 inch drive, powered by a 20V battery and weighing 1.8 lb, sized for tighter spaces than a full-size 1/2 inch impact.

A 3/8 inch drive puts this impact wrench a step below the more common 1/2 inch size, which generally means less torque but a smaller head that reaches into tighter engine bays or under-dash spots. The 20V battery and 1.8 lb weight point to a tool built for maneuverability over raw output.

Who it's for

Works well for auto and motorcycle work involving smaller fasteners in cramped spaces. Not the choice for large truck lug nuts or heavy equipment fasteners that call for a bigger drive and higher torque.
