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

This is the 110V transformer version of the benchmark DWS780 for sites that require reduced-voltage tools, with the same 305mm blade, 303 × 110mm capacity at 90°, dual bevel and XPS shadow-line guide. Like the 240V model it uses conventional rear sliding rails, so it needs clearance behind and is a 25.5kg fixed-shop saw. We rate it the default 305mm site saw on 110V supply; for a flush-to-wall alternative look at the Makita LS1219L/1.
