Overview

The Bosch PS21-2A is a 12 volt cordless drill driver weighing 1.4 pounds, with a 2 amp rating and a 1300 RPM top speed built for compact, one-handed driving.

The -2A designation in Bosch's naming typically points to a kit bundled with a 2.0Ah battery, and the combination of light weight and a 1300 RPM top speed positions this as a pocket driver rather than a heavy-duty drilling tool, trading raw power for portability on quick fastening jobs.

Who it's for

Fits buyers who want a small, light driver for quick screw-driving tasks around the house or jobsite where a full-size drill would be overkill. Not the right pick for anyone needing to bore large holes or drive long lag screws.
