Where it sits among 125mm angle grinders

Scaled against the 59 angle grinders with a 125mm disc we list, so other sizes aren't in the mix. Not a score: bigger isn't always better for your job.

The verdictOur take

The specialist of the family. Its flat gear head sits far lower than a normal grinder, working into acute angles of around 42 degrees and tight corners a standard head can't reach, which makes it a genuine fabrication and access tool. It's also the smoothest of Milwaukee's M18 125s at 4.32 m/s², on a paddle deadman switch with the usual RAPIDSTOP brake and Anti-Kickback Protection. For weld dressing, prep and grinding in confined spaces it earns its place; for general use the standard 125s stay more flexible.
