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.

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.

  • 24500 RPM cordless motor
  • 1.2 pound item weight
  • About 11 x 4 x 4 inch dimensions

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.

Pros and cons

Pros
  • Compact and light at 1.2 pounds
  • 24500 RPM suits deburring and detail grinding
Cons
  • 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.
