Overview
The Milwaukee 2904-20 is a battery powered drill/driver with a top speed of 1800 RPM and a listed weight of 3 pounds, sold as the bare tool since the -20 suffix in Milwaukee's numbering typically denotes tool only, without battery or charger.
The listed dimensions of 3 inches on every side do not match a usable drill footprint and likely reflect packaging rather than the tool itself, so that figure is left out of the specs below. Milwaukee's M18 platform this tool draws from is a widely stocked cordless system, which matters mainly for battery compatibility.
- Battery powered M18 platform
- 1800 RPM top speed
- 3 pound listed weight
- Milwaukee 2904-20 bare tool model
Who it's for
Fits anyone already holding Milwaukee M18 batteries who wants a bare tool add on rather than a full kit, since no battery or charger appears to be included based on the model suffix.
Pros and cons
- Compatible with Milwaukee's widely used M18 battery platform
- Light at 3 pounds for extended handheld use
- Likely bare tool only, battery and charger not included
- Listed dimensions appear to reflect packaging, not the tool
Performance notes
A 1800 RPM top speed is typical for a general purpose drill/driver rather than a high speed impact tool, suited to driving screws and drilling smaller diameter holes rather than heavy demolition work.
