Overview
The DeWalt DCS389B is a 60 volt cordless reciprocating saw sold as a bare tool, with an 8 inch cutting capacity and a high speed steel blade material spec, weighing 7.4 pounds without a battery.
This is DeWalt's FLEXVOLT class recip saw, built for demolition and remodeling cuts rather than fine work. The DCS389B designation with a B suffix means the tool ships without a battery or charger, so budget for a compatible 60 volt or FLEXVOLT pack separately.

Who it's for
