Makita 1100W SDS+ Rotary Hammer Drill 110V HR4011C

Two unique Makita features contribute to the super-safe, low vibration benefits of this advanced machine, the patented Makita, AVT Anti Vibration Technology system uses the pneumatic pressure generated in the hammer piston chamber to move a counter balance in the opposite direction to dampen out the impact vibrations at the steel point. This dramatically reduces machine produced vibrations and in addition to the advanced AVT system, this new Makita 5kg hammer features the 2-Mass fulcrum hinged rear grip handle and the vibration damping side handle to further limit HAV risks.
