Overview

The Milwaukee 2656-20 is an 18 volt cordless impact driver that runs on Milwaukee's M18 battery platform, weighing 1.5 pounds and spinning up to 2750 RPM. The dash-20 model number indicates a bare tool sold without battery or charger.

This is Milwaukee's compact M18 impact driver body, built for driving screws and fasteners rather than high torque bolt removal. Since it ships bare, buyers already invested in M18 batteries get the best value, while first time buyers need to budget separately for a battery and charger.
