Makita Demolition Hammer HM1307C The Demolition Hammer Makita HM1307C is powered by a 1,510W motor that provides 730 ~ 1,450 ipm to increase efficiency. This Demolition Hammer features an electrical speed control that maximizes performance, and the LED lamp indicates when it's time to replace the carbon brush. Additionally, This Jack Hammer Double Insulation protects the user, the variable speed allows the user to control the speed, the Constant speed to the motor to maintain speed under load, the Soft start to ensure smooth starting, and Dust Collecting reduces the amount of dust produced during cutting. Powerful Features: Double insulation: Double or reinforced insulation is another method of protection against electric shock, consisting of an extra layer of supplementary insulation over the basic insulation, or the live parts. Double insulation devices protect the user through two independent isolation systems. These systems protect electric motor components from the outer motor housing and tool holding areas. Variable speed: Variable speed control allows the user to match the speed to the application they are working on. Constant Speed: Constant speed control automatically applies additional power to the motor to maintain speed under load. Soft Start: Soft start prevents start-up reaction to ensure smooth starting, longer gear life, and better accuracy when starting work. Dust Collecting: The dust collector is designed to reduce the amount of dust produced during cutting and concrete dust generated during drilling on the job site, allowing you to work efficiently and comfortably.
