Overview
Twenty volts, 3000 strokes a minute, and an 8 inch cut capacity define the DEWALT DCS380B reciprocating saw. At 2.41 kilograms it stays maneuverable for demolition and remodeling cuts near ceilings or wall cavities.
DeWalt's 20V MAX platform runs this saw, so it shares batteries with the rest of that cordless lineup rather than needing a dedicated charger. The 8 inch capacity and high speed steel blade material point to general demolition and framing cuts rather than fine finish work. No seller copy or reviews are attached to this listing, so this page relies on the spec sheet alone.
