The DeWalt DCS391B is a bare-tool 6-1/2-inch cordless circular saw that runs on the brand's 20V Max batteries. It spins at 5,150 rpm and has a bevel adjustment for angled cuts, which makes it a light, one-handed saw for framing, decking and sheet goods. It ships without a battery or charger, so it only makes sense if you already own DeWalt 20V packs. The best new price is $135.45 at JB Tools as of November 7, 2026, and only one store lists it new, so there is little price competition to wait for.

Owners of the DCS391B generally treat it as a dependable cordless saw for framing and general cutting, with power that surprises people coming from older 18V tools. Complaints center on the bare-tool packaging, the modest cut depth and the lack of a brake.
