Overview
The Milwaukee 2486-20 is a cordless die grinder running at 24500 RPM, weighing 1.2 pounds and measuring about 11 x 4 x 4 inches. It holds a 4.6 star rating from 686 reviews, with 200 units bought in the past month.
Listed under Tools and Grinders, the 2486-20 is built for close quarters grinding, deburring and polishing where a full size angle grinder will not fit. Its light 1.2 pound weight and compact body point toward one handed use, though the listing captured here has no seller description confirming included accessories or whether a battery ships with the tool.

Who it's for
Fits metalworkers, fabricators and hobbyists who need a small cordless grinder for detail work, deburring welds or reaching tight spots. Less suited to anyone needing heavy stock removal, since a 1.2 pound tool at this size is built for precision work rather than bulk grinding.
Strengths and trade-offs
Drawn from this product's published specifications.
- Compact and light at 1.2 pounds
- 24500 RPM suits deburring and detail grinding
- 4.6 star rating across 686 reviews
- 200 units bought in the past month
- No confirmation a battery ships with it
- Not sized for heavy stock removal
Performance notes
At 24500 RPM the motor spins fast enough for deburring and light polishing work rather than aggressive material removal, and the 1.2 pound weight keeps the tool maneuverable in one hand for extended use. Cordless die grinders of this size typically run off a separate battery pack, so runtime depends on which battery is paired with the tool.
