Where it sits among 305mm mitre saws

Scaled against the 14 mitre saws with a 305mm blade 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 GCM 340-305 D is a 305mm dual-bevel slider with a huge 340 × 105mm crosscut and an LED cut-line light. 21.4kg, so it's one for the workshop or a stand.
