The DHR281ZJ rotary hammer, including quick-change chuck, is powered by 2x18V LXT batteries that power the 3 operating functions: rotation only/rotation and hammer/hammer only.
This unit comes equipped with an LED joblight and variable speed trigger, as well as an electric break to stop the tool near-instantly in order to keep you safer at work; a soft-no load system that eases any excessive forces when idling to allow you to properly control the unit when it's not in use, which saves stress and strain on your joints; plus a brushless motor, which reduces friction and increases the efficiency of energy transfer, meaning that your tool will be able to do more on a single charge! It's also torque limited and included anti-vibration technology to reduce the risk to you.
