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 GWX 18V-15 P is Bosch's BITURBO 125mm grinder, rated like a 1,500W corded tool, with X-LOCK, X-Brake, KickBack Control and soft start. Bosch recommends a 5.5Ah ProCORE pack or bigger.
