18V SDS Rotary Hammer Drill with Brushless Motor Technology25% more power – Brushless motors have fewer moving parts results in a quiet motor that never needs maintenance. The reduced friction enables a better use of available energy from the battery pack as there is no resistance from brushes50% more run time – Brushless motor technology means the carbon brush resistance is eliminated, so less battery energy is wasted. The efficiency of a brushless motor results in a greater run time from each chargePowerful 4-function Brushless SDS Rotary Hammer Drill is ideal for drilling into concrete, brick and masonry.Incorporates a rotary stop mode for light chiselling in tiles, render and plaster.Slide function SDS chuckMulti-positional side handle for operational convenience
