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 flat-head version of the DCG405, with a slimmer flush gear case that gets the disc closer into corners and under obstructions where a standard head will not fit. Same 18V XR brushless platform, slide switch and full Perform & Protect safety set (Kickback Brake, E-Clutch, soft start, Power-Off overload). Worth the small weight penalty over the standard 405 if you regularly grind in tight or awkward spots.
