1-3/4" AVT® Rotary Hammer, accepts SDS-MAX bits
Model HR4510C
Anti-Vibration Technology for 2X Less Vibration
  • 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 increased accuracy
  • L.E.D. service light notifies the user approximately 8 hours before the brushes need to be replaced
  • L.E.D. 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
  • One-touch sliding chuck for quick bit changes
  • Lock-on switch for continuous operation ("Hammering Only" mode)
  • Rubberized ergonomic soft grip provides added comfort
  • Makita Motor Advantage engineered with field core interlocking steel laminations, dual ball bearing armature and more copper commutator bars, increasing energy transfer efficiency for more power and longer tool life
