Background and Identification
The Makita model HM0870C is a breaker hammer produced by Makita. A jackhammer or demolition hammer is a pneumatic or electro-mechanical tool that combines a hammer directly with a chisel. Jackhammers are typically used to break up concrete, pavement, and rock. Hand-held jackhammers are generally powered by compressed air or electric motors.
The Makita Breaker Hammer HM0870C features anti-vibration technology (AVT) and a counterbalance system to reduce vibration. It includes a 10-Amp motor that provides 1,100 to 2,650 blows per minute and 8.4 foot-pounds of impact energy per blow. It features constant speed control that automatically applies additional power to the motor to maintain a constant speed under loads. A soft-start feature suppresses start-up reactions for more user control, and 12 bit-angle settings allow the user to change the angle for various applications. It accepts SDS-MAX bits with a 3/4-inch chuck size.
The demolition hammer includes one handle with a rubberized grip. The HM0870C model includes a variable speed control dial that allows the user to match the speed of the hammer to the application. An LED service light notifies users approximately eight hours before the hammer’s brushes need to be replaced. An LED power light indicates switch failure or cord damage. The HM0870C model is part of Makita’s line of teal power tools and can be identified by its teal body and black details. The name “Makita” is printed in white capital letters on the side of the breaker hammer.
