## Summary

The M18 FSAG125XB is a 125 mm grinder with a slide lock-on switch for long grinding passes. Milwaukee compares it to a 1,200 W corded grinder; RAPIDSTOP brakes the disc in under two seconds.

## Why this one

- **RAPIDSTOP**: Disc stops in under two seconds.
- **1,200 W class**: Corded-class grinding on an 18V pack.
- **Slide lock-on switch**: Comfortable for long grinding passes.
- **FIXTEC**: Tool-free disc changes.

## The story

### For long passes

Metalworkers and installers who grind welds, clean steel or cut long runs of tile prefer a slide switch they can lock on. This grinder cuts 33 mm deep with 125 mm discs and runs at 8,500 rpm, which Milwaukee rates as matching a 1,200 W mains grinder.

### Protection built in

RAPIDSTOP brakes the disc in under two seconds, anti-kickback cuts power if the disc catches, soft start avoids a jolt and line lock-out stops a restart after a pack change. A smaller gear head and lower battery angle improve balance over earlier models.

### Discs and packs

FIXTEC lets you change discs without a spanner, and the keyless guard adjusts by hand. The kit includes two 5.0 Ah batteries in an HD Box. Keep grinding discs, flap discs and a diamond blade for concrete in the box and one grinder covers most jobs.
