Overview

The AO-DW is a 20 volt cordless impact driver, model AO-DW. It fits standard 20V battery tool lines for driving screws and fasteners without a cord.

Impact drivers in the 20V class trade the smooth chuck of a drill for rapid rotational bursts that seat screws and lag bolts without stripping heads or stalling. This listing supplies only voltage as a hard spec, so runtime, torque rating, chuck type and battery inclusion all need checking on the product page before buying.

Who it's for
