Anti-Vibration Technology (AVT®) is a counterbalance system inside the tool that significantly reduces vibration. The AVT® counterbalance design is based on seismic engineering, which developed this damping science to absorb shocks and protect buildings from earthquakes. AVT® uses a mechanical damper, effectively a counterbalance weight inside the tool, that provides an equal and opposite force that puts a mass directly opposite the point where the striker bolt delivers the impact. As vibration is eliminated, power is efficiently increased which allows more of the generated energy in the motor to be delivered to the tool bit. Makita also has an AVT® counterbalance system in select recipro saws. For users, AVT® means significantly less vibration with no compromise in power and performance. [Learn More]
The Makita 45 lb. Demolition Hammer (HM1512) has a powerful 15 AMP motor that delivers 35.7 ft.lb. of impact energy to handle demanding concrete applications. This demolition hammer features Anti-Vibration Technology (AVT®), an internal counterbalance system along with vibration-absorbing handles that work together to reduce vibration. The in-line body design is better adapted for working in narrow spaces and provides improved balance for maneuverability. The Soft Start feature suppresses start-up reaction for smoother starts and better accuracy. The demolition hammer has dust extraction capability with the optional dust extraction kit (sold separately). The hex-style chuck accepts 1-1/18 in. steel bits.
