This Rotary Hammer is suitable for drilling into concrete, wood, and steel. 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. Reversing: After drilling, setting the bit direction to reverse spins it counterclockwise to help it come out of the hole cleanly and easily. You'll also use reverse mode to quickly remove screws and other fasteners. Torque Limiter: A torque limiter is a built-in clutch that reduces gear damage by disengaging gears if the bit binds. Makita Rotary Hammer Drill Features: Operation mode change lever positioned on the bottom of gear housing for reduced possibility of breakage. Adapted for SDS-PLUS bits.
