The FLEXVOLT 60V MAX Brushless 1-9/16" SDS Max Combination Hammer is a light weight high-performance hammer that is powered by a DEWALT brushless motor and durable German engineered mechanism. The DCH481 delivers 6.1 joules of impact energy for fast drilling, even in the hardest concrete. The lightweight design makes it ideally suited for horizontal serial drilling for #4 - #8 rebar, dry coring and chipping in any mid to upper wall and ceiling application. The patented E-Clutch system provides enhanced control to the user in a bind up situation and can help minimize sudden torque reaction compared to standard clutches. The Active Vibration Control technology employed delivers reduced user vibration for less user fatigue and greater productivity. With its balanced design, SHOCKS Active Vibration Control technology and Extreme Run Time, this hammer is ideally suited for all day use, even in the hardest concrete.
