The DCM848B is a cordless random-orbit polisher that runs on DEWALT's 20V MAX batteries. It spins a 5-inch backing plate at 2,000 to 5,500 orbits per minute, set by a variable-speed trigger plus a separate speed dial, with a 2.1-inch orbit for swirl-free paint correction. It suits detailers and car owners who want polisher performance without a cord and already own DEWALT 20V packs. Against corded dual-action polishers it trades unlimited runtime for portability, and it is heavier and pricier than entry-level corded units. It ships as a bare tool, so batteries and a charger are extra.
