Makita’s hard-hitting HM1317CB 42 lb. Breaker Hammer is engineered for heavy chipping, demolition and breaking applications, but with less vibration for increased user comfort. The HM1317CB is equipped with Anti-Vibration Technology (AVT®), an internal counterbalance system that is engineered into the tool for more effective vibration reduction. It is an ideal solution for heavy structural demolition like breaking up driveways and sidewalks, as well as for landscape and trenchwork, asphalt removal, driving ground rods, and more.
The HM1317CB has a 14 AMP motor that delivers 730-1,450 BPM and 34.9 joules of impact energy. It features Makita's electronic controller so users will benefit from the soft start, as well as a variable speed control dial, an L.E.D. service light that notifies users before brushes need to be replaced, and constant speed control that automatically applies additional power to the motor to maintain speed under load for the most challenging jobs. For added convenience, the HM1317CB has a 16.4 ft. cord and accepts the popular 1-1/8” Hex bit type.
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.
FEATURES
