Overview
The Milwaukee 2904-20 is a cordless drill/driver built on the M18 FUEL brushless platform, sold as a bare tool for users already invested in Milwaukee's battery system. It weighs about 16 ounces and is aimed at drilling and driving tasks across trades.
As a bare tool, the 2904-20 is priced and packaged for anyone replacing a worn out drill body or building a mixed M18 kit rather than starting from scratch. Brushless motors like this one typically run cooler and last longer under repeated use than brushed equivalents.
- M18 FUEL brushless platform
- 16 ounce tool weight
- 18 volt battery compatibility
Who it's for
Works well for tradespeople with existing M18 batteries who want a lighter drill/driver for daily use. Not a fit for someone without any M18 batteries or chargers already on hand, since none are included.
Pros and cons
- Very light at about 16 ounces
- Brushless motor for durability
- Compact dimensions for tight spaces
- Sold bare with no battery or charger
- Speed rating in the listing appears limited to one setting
Performance notes
At roughly 16 ounces this is one of the lighter tools in its class, which reduces wrist fatigue on overhead or repetitive drilling. The listed 650 RPM speed rating sits at the lower end for a drill/driver, suggesting this spec reflects one gear or setting rather than the tool's full range.
