The DeWalt DCH133B is a cordless 1-inch SDS-Plus rotary hammer built on the 20V MAX XR battery platform. Its brushless motor and German-engineered hammer mechanism deliver 2.6 joules of impact energy, which DeWalt rates as faster than comparable corded hammers. A mechanical clutch limits torque kickback if the bit binds, and the tool accepts the D25301D dust extractor. It suits remodelers, electricians and concrete crews who want corded-class drilling without a cord, though it is sold as a bare tool with no battery or charger.

Owners treat the DCH133B as a corded replacement for light concrete work, praising its power-to-weight ratio and smooth drilling. Complaints center on runtime with small batteries and the lack of a chisel mode.
The DeWalt DCH133B is a cordless 20V MAX XR brushless 1" D-handle rotary hammer. It uses a German-engineered mechanism that delivers 2.6 joules of impact energy. The tool is compact and light, with a balanced design.
A brushless motor drives the hammer mechanism. The electronics let the tool keep its speed through the whole application, even with the largest bits. A mechanical clutch gives the user more control if the bit binds and can help minimize sudden torque reaction.
It is dust extraction ready for the D25301D. The compact size allows access to space-restricted areas.
