Makita HR4511C SDS Max Rotary Demolition Hammer Drill with AVT, complete with 2 side handles, depth stop, bit grease and carrying case This Demolition Hammer features Makita's Anti Vibration Technology which dramatically cuts down the amount of vibration being transferred to the operator resulting in much less user fatigue. This works with an internal balancer which is moved by the air pressure created inside the drill housing by the hammer action. The balancer moves in the oposite direction thus acting as a perfectly timed counterbalance. This technology coupled with the padded, spring loaded, hinged rubberised grip means the HR4511C is unleashing all it's power in a forward motion, enabling it to be used for long periods of time with little vibration transferral to hands and arms.
