The DeWalt DCS438B is a 20V MAX XR brushless 3 in. cut-off tool sold as a bare tool. It spins a 3 in. wheel at 20,000 rpm and cuts up to 0.8 in. deep through metal, tile and multi-material stock. Three wheels, a dust shroud with AirLock extraction and tool-free depth and guard adjustment come in the box. It suits tradespeople already on the 20V MAX battery platform who want a compact, spark-controlled cutter; rivals like the Milwaukee M12 cut-off saw trade battery size for a smaller body, while this tool leans on the larger 20V packs and DeWalt's extractor ecosystem.

Rated 4.7 out of 5 from 51 ratings. Owners like the compact size, the included wheel selection and the dust shroud; the main gripes are that it ships without a battery and that the depth of cut is limited.
