Overview

Milwaukee's 2485-20 is a 12-volt battery powered grinder spinning at 24,500 RPM and weighing 1.6 pounds. Measuring 4.4 x 2 x 8.7 inches, it's sized for one-handed use in tight spaces.

The RPM here, 24,500, runs well above typical corded angle grinders, pointing to a compact cutting or grinding tool built for speed over material removal capacity. At 1.6 pounds and under 9 inches long, it's built for reach into confined spots rather than heavy surface grinding. It draws from Milwaukee's 12V battery platform, so it shares batteries with other tools in that line.

Who it's for

Users already invested in Milwaukee's M12 battery platform who need a compact, high-speed grinder for tight or overhead spots. Not for heavy-duty surface grinding, where a larger corded or higher-voltage tool suits better.

Strengths and trade-offs

Drawn from this product's published specifications.

What stands out
  • Compact 1.6 pound body for tight spaces
  • High 24,500 RPM speed
  • Shares batteries with Milwaukee's M12 line
What to check first
  • 12V platform limits power versus larger grinders
  • Not suited to heavy material removal

Performance notes

At 24,500 RPM, it spins faster than most full-size angle grinders, which suits fine cutting and grinding work more than heavy material removal. The 1.6 pound weight and compact 4.4 x 2 x 8.7 inch body make it easier to hold one-handed or work overhead than a full-size grinder.
