This Makita HM1500B demolition hammer rental has an innovative pneumatic compression system which automatically adjusts air in the cylinder to minimize power loss and deliver an unmatched power-to-weight ratio. It has a special idling mechanism (patented) which reduces hammering while idling. The side handle swivels 360 degrees for operator comfort and control and the anti-vibration system in the main handle markedly reduced operator fatigue. And, of course, it has a powerful 13.5 AMP electric motor. Also known as jack hammer or concrete breaker or power chisel or braker or handheld concrete chipper.
