The 70 lb. AVT Breaker Hammer (HM1812) is engineered to hit like an air hammer, but with less noise and vibration. It has a powerful 15 amp motor that delivers a full 53.9 ft. lbs. (73.8 Joules) of impact energy. Users benefit from less noise and lower vibration than an air hammer, and zero hassle with an air hose and compressor. The HM1812 features the latest advanced AVT technology, a synchronized three-component system that more effectively reduces vibration. The internal mechanical counterbalance system, vibration-absorbing housing, and fixed movement handles are engineered for significantly less vibration during concrete breaking applications.
