This cordless 20V rotary hammer from Dual Power features a brushless motor that can handle any task. You can drill, hammer drill, chisel, and break through wood, stone, steel, or brick with up to 4750 blows per minute. The efficient brushless motor not only extends the machine's lifespan but also delivers an impact force of 3 joules, providing enough power for heavier jobs. Additionally, the machine can be used for lighter chisel work. To ensure comfortable operation at all times, the rotary hammer produces less vibration and fits well in your hand with its soft-grip handle. The practical work light allows you to work easily in dark areas, and the dust protection cap captures a significant amount of dust, enabling you to work in a dust-free environment.
