The D25651K 1-3/4" Spline Combination Hammer, with its durable and hard hitting German engineered mechanism, delivers 8 joules of impact energy. The patented two-stage clutch and 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 light weight design makes it ideally suited for horizontal serial drilling for #5 - #8 rebar, coring and chipping in any mid to upper wall and ceiling application. The Active Vibration Control® technology employed delivers reduced user vibration for less user fatigue and greater productivity.
