Powerful 11 AMP motor delivers 8.4 ft.lbs. 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 5m/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

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

L.E.D. service light notifies the user approximately 8 hours before the brushes need to be replaced

L.E.D. 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 commutator 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

One-touch sliding chuck for quick bit changes
