Article Number:
  • $ 77999

Powerful 13.5-Amp motor delivers 9.2 ft. lbs. of impact energy to handle the most demanding applications . 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 lights indicate switch failure or cord damage . Anti-vibration technology is an internal counterbalance system that greatly reduces vibration and directs more impact energy to the work surface for increased user comfort and greater productivity . 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 . Extended life brushes are longer for more work between service intervals and less downtime . Automatic brush cut-off protects commutator from damage for longer tool life . 2-mode operation for "hammering only" or "hammering with rotation" for multiple applications . 16 bit angle settings allow the bit to be set at different positions for operating convenience . 1-touch sliding chuck for quick bit changes . Lock-on switch for continuous operation ("hammering only" mode) . Rubberized ergonomic soft grip provides more comfort and control . 1 year warranty . Includes: side handle (151769-0), D-handle (417003-1), depth gauge (321248-4), bit grease (194683-7), tool case (158275-6) . High Quality Protection Plan:

Tough on concrete, not on you: Makita’s hard-hitting HR4510C 1-3/4 in. SDS-MAX Rotary Hammer is equipped with Anti-Vibration Technology (AVT), an exclusive counterbalance system that reduces vibration. The result is more efficient hitting on the concrete and less vibration in the tool – and the tool user. The HR4510C with AVT is engineered with a 13.5-Amp motor that delivers a no load speed of 130 to 280 RPM and 1,250 to 2,750 BPM. The synchronized RPM and BPM prevent overlapping impacts for up to 50% more efficient drilling. The hammer features 2-mode operation: “hammering with rotation” and “hammering only”, with a built-in torque limiter that ensures stable torque control and disengages the motor should the bit bind or hit reinforcements. In addition, the electronic speed control reduces speed loss when working in heavy applications to ensure maximum productivity.
