It is best suited for professional contractors needing versatile fastening capabilities.

The Craftsman V20 Cordless Brushless Impact Driver is a compact, mid-range tool designed for DIYers and light trade professionals seeking affordable power for driving large fasteners. It features a brushless motor for extended runtime, variable 3-speed settings, and a 1,700 in-lbs torque output, assembled in the USA with global materials.
