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 DCS781 is DeWalt's single-battery 54V FlexVolt 305mm dual-bevel slide, cutting 310 × 90mm at 90° with an electronic brake, the XPS shadow line and wireless extractor starting through DeWalt's built-in Wireless Tool Control. It brings near-full 305mm capacity off one FlexVolt battery, where the older DHS780 needs two. We rate it the cordless 305mm pick for FlexVolt sites wanting single-battery convenience; the twin-battery DHS780 edges it on vertical capacity (110mm) for tall stock cut on edge.
