The 20V MAX* XR Brushless 1-inch Rotary Hammer is a high-performance drill powered by a DEWALT brushless motor and a durable German engineered mechanism, delivering 2.1 Joules of impact energy. The light weight design makes this tool ideal for overhead 1/2-inch dropin drilling. This drill is also part of the PERFORM & PROTECT product line with the SHOCKS ACTIVE VIBRATION CONTROL System. This DEWALT cordless hammer drill kit provides OSHA Table 1 Compliance by pairing the rotary hammer with the DWH303DH On Board Extractor. The 2-second power-off delay ensures that dust extraction continues after the drill is switched off. The extractor also features a durable, clear high-capacity dust box, a replaceable dust nozzle, a replaceable HEPA filter, and quick release for easy attachment and disassembly.
