The digital, brushless motor provides the power needed to quickly hammer through tough materials like brick, stucco, and concrete with 0-1400 RPM and 0-4500 IPM. Seamless transitions between hammer drill, drill, chisel, and chisel alignment modes reduce time and increase efficiency, while the PWRCore 20 Lithium Battery and Automatic PWRJump Charger keep your SDS hammer drill powered up longer.
