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

DeWalt's long-running 18V XR 125mm grinder, and on the numbers one of the smoothest in the range: its declared 4.4 m/s² vibration is the lowest of the DeWalt 125mm models we list and among the lowest of any. The slide switch with lock-on favours sustained grinding, and it carries the full Perform & Protect safety set (Kickback Brake, E-Clutch, soft start, Power-Off overload). A dependable pick for anyone already on 18V XR who wants the safety kit without moving to FlexVolt power.
