Model: Makita HR5212C
52mm ( 2-1/16") SDS Max, AVT Rotary Hammer 1510W
FEATURES:
- Powerful 1,510 W motor delivers 20 J of impact energy to handle the most demanding applications
- Anti-Vibration Technology (AVT) is a synchronized, three-component system that more effectively reduces vibration resulting in a low 9 m/s²
- Air actuated counterbalance directs air pressure from the crank and barrel room into the counterbalance cylinders to move counterweight pistons in the opposite direction of the drive piston actively reducing vibration
- Vibration absorbing housing features a spring loaded main handle and upper housing that move independently of the motor and drive mechanism effectively isolating most of the vibration away from the user both at the rear handle and side handle
- Integrated damper spring at the base of the impact bolt is engineered to absorb impact vibrations from the drill bit
- Lock-on or trigger activation in “Chipping Only” mode with a push button start/stop control
- Constant speed control automatically applies additional power to the motor to maintain speed under load to complete the most challenging jobs
- Soft start suppresses start-up reaction for more control and better accuracy
- LED service light notifies the user approximately 8 hours before the brushes need to be replaced
- LED power light indicates switch failure or cord damage
- Variable speed control dial enables user to match the speed to the application for greater versatility
- Torque limiting clutch engineered to minimize gear damage by automatically disengaging gears if the bit binds
- Sequential impact timing delivers timed hammering during rotation to minimize overlapping bit impacts for up to 50% faster drilling
- Depth gauge for increased drilling consistency
- Double insulated
