Makita is continuing to expand their line of concrete hammers with Anti-Vibration Technology and that includes the new 1-9/16-inch HR4013C AVT Rotary Hammer. They say is has 45% less vibration and 20% more impact energy than their own previous model, and that it is the leader of its class.
Similar to what we saw with the smaller 1-inch HR26 model, Makita uses a counterbalance to help cancel out the forces that cause vibrations. In this model the counterbalance system is an air actuated cylinder. They also use a damper spring at the base of the impact bolt, and a spring loaded handle; both of which also absorb and isolate vibrations.
Features include a constant speed control that keeps the tool running at speed even under load, a soft start function, 2-mode hammering/rotation + hammering operation, and 24 bit angle settings.
With an 11amp motor offering 11.4 Joules (8.4 ft. lbs.) of impact energy, Makita says the HR4013C is suited for a range of applications including: drilling/coring through-holes for pipes, setting larger anchors, securing tilt-wall supports, small chipping applications, and more. - Amazon
