Where it sits among 230mm angle grinders

Scaled against the 26 angle grinders with a 230mm 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

Milwaukee's headline act, billed as the first 9in grinder to run on a single 18V battery, with Milwaukee quoting up to 68 cuts per charge in 42mm stainless pipe. At 230mm and 6,600 rpm it's made for heavy cutting and chasing you'd normally reach for a corded 9in to do, and the RAPIDSTOP brake and Anti-Kickback Protection matter even more at this size. The trade-off is weight: 4.3kg with a 4.0Ah battery, so it suits bursts of serious cutting more than all-day handheld work. Milwaukee's declared vibration is 5.5 m/s² for surface grinding. If you've been waiting to cut the cord on a 9in, this is what makes it viable.

Tool weight worked out by adding each pack's weight to the bare tool, using the makers' figures. The maker's own with-battery figure can differ slightly. We may earn a commission on retailer links.
