Battery revolution: The Dewalt 54 Volt XR Flexvolt range of machines offers power for the toughest applications without cables. Brushless motor technology provides higher performance, more compact dimensions, and longer service life. This powerful SDS-max cordless combi hammer delivers 19.4 joules of single impact energy. Perfectly coordinated rotation and impact speed, along with constant speed electronics, guarantee consistently high drilling progress. The mechanical safety clutch ensures trouble-free, safe use even with larger drilling diameters. Cooling air ducting in the percussion components extends service life. Perform & Protect: Safe and fatigue-free work with low vibrations is achieved through the spring-loaded handle that is decoupled from the machine. Electronic rotation and impact speed regulation via the throttle switch allows perfect adaptation to the material being processed. The rotation stop enables medium-heavy chisel work in masonry, stone, and concrete. Wireless Tool Control (WTC) allows for automatic, wireless switching on of a suction cup when starting the machine.
