Overview
Cordless and running on Milwaukee's 12 volt platform, the 2438-22 spins up to 8300 RPM and weighs 5.3 pounds as a kit, built for speed rather than heavy torque.
Milwaukee files this one under specialty tools rather than a mainstream drill or driver category, and the spec sheet backs that up: a 12 volt cordless platform running at a brisk 8300 RPM. That combination points to a tool built for speed on smaller fasteners or fittings rather than heavy demolition work.
