Power Tools Makita Rotary Hammers | Makita Grh05Z 40V Max Xgt Brushless Lithium-Ion 1-9/16 In. Cordless Avt Rotary Hammer (Tool Only)

The 40V Max Xgt Brushless 1-9/16 In. Avt Rotary Hammer (Grh05Z, Tool Only) Is A Cordless Concrete Solution Designed For Heavy-Load Applications. It Delivers The Power, Speed, And Run-Time For Corded Demands, Without The Cord. The Grh05Z Features Active Feedback-Sensing Technology (Aft), Which Electronically Turns Off The Motor If Rotation Of Bit Is Suddenly Forced To Stop, And Anti-Vibration Technology (Avt) For Reduced Vibration. More Than Just A Padded Handle, Avt Is An Internal Counterbalance That Uses Air Pressure To Move Counterweight Pistons In The Opposite Direction Of The Drive Piston To Actively Reduce Vibration. In Addition, The Vibration-Absorbing Back Handle And Side Handle Further Reduce Vibration. For Added Durability In Harsh Job Site Conditions, Extreme Protection Technology (Xpt) Is Engineered For Improved Dust And Water Resistance.
