The Rotary Hammer ensures less vibration while you work with its Anti-Vibration Technology, a synchronized 3-component system. This versatile tool is great for a wide range of applications including masonry, concrete, demolition, plumbing and electrical jobs. Its 15-Amp motor delivers 19.1-Joules of impact energy to handle the toughest jobs, from drilling and coring through-holes in pipes to setting large anchors. In the "chipping only" mode, choose between lock-on or trigger-activated with push button start/stop control for ease of operation.
Powerful 15 Amp motor delivers 14 ft. lbs. of impact energy to handle the most demanding applications
Anti-vibration technology (AVT) is a synchronized, 3-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 for more convenient operation
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 prevent 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
Automatic brush cut-off protects commentator from damage for longer tool life
2-mode operation for chipping only or hammering with rotation
24 bit angle settings allow the bit to be set at different positions for operating convenience

I have drilled hundreds of deep 1-1/2" holes in granite with my HR5212C is the best drill that I have used by far I have used 4 other manufacturers 2" class SDS MAX drills it has drilled more holes than all of my other drills combined it dose not over heat and it hits harder than my other drills.
