Makita Hex Advanced AVT Breaker Hammer Product Image

Makita Hex Advanced AVT Breaker Hammer Handles the Most Demanding Applications

The new 70 lb. AVT Breaker Hammer 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, so contractors get hard-hitting performance. Users also 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. Model HM1812X3 is a kit and also includes a Premium Hammer Cart, as well as two 1-1/8 in. x 20-1/2 in. Flat Chisels (1-1/8 in. Hex) and two 16 in. Self-Sharpening Bull Point bits (1-1/8 in. Hex).
