The SDS-Max concrete bit is designed specifically for larger hammer drills that use the quick disconnect chuck that accepts the SDS-Max style shank.The longer SDS-Max concrete bits are used to drill through holes for running electrical conduit or other type of pipes.



Automatic brush cut-off protects commutator from damage for longer tool life.service light notifies the user approximately 8 hours before the brushes need to be replaced power light indicates switch failure or cord damage Sequential impact timing delivers timed hammering during rotation to minimize overlapping bit impacts for up to 50% faster drilling.Torque limiting clutch engineered to prevent gear damage by automatically disengaging gears if the bit binds.Variable speed control dial enables user to match the speed to the application for greater versatility."Soft no-load" function automatically reduces the speed of the motor when idling to help increase tool life and performance.Soft start suppresses start-up reaction for more precision and better accuracy.Constant speed control automatically applies additional power to the motor to maintain speed under load to complete the most challenging jobs.Advanced AVT® includes an integrated damper spring at the base of the impact bolt engineered to absorb impact vibrations from the drill bit.Advanced AVT® includes a vibration absorbing housing with a spring loaded back handle and housing which moves independently of the motor and hammer mechanism effectively isolating more vibration away from the user.Advanced AVT® includes an air actuated counterbalance that directs air pressure from the crank and barrel room into the counterbalance cylinders to move counterweight pistons in the opposite direction of the hammer mechanism to effectively reduce vibration.

Advanced Anti-Vibration Technology (AVT®) is a synchronized, three-component system that more effectively reduces vibration resulting in a low 5m/s2.of impact energy to handle the most demanding applications Powerful 15 AMP motor delivers 14 ft.lbs.
