Where it sits among 165mm circular saws

Scaled against the 19 circular saws with a 165mm 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 DCS391 is DeWalt's long-running 18V XR 165mm saw: 55mm at 90° is enough for 45mm timber and sheet work, with a bevel to 50°. It's the brushed, simpler option; the brushless DCS570 is the upgrade.
