1-9/16" Rotary Hammer, accepts SDS-MAX bits
Model HR4001C
Increased Power with Reduced Vibration
  • Powerful 11.0 AMP motor; 1,350-2,750 BPM 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
  • Variable speed control dial enables user to match the speed to the application for greater versatility
  • 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
  • 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, resulting in up to 50% more drilling efficiency
  • 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
  • Automatic brush cut-off protects commutator from damage for longer tool life
  • 2-mode operation for "Hammering Only" or "Hammering with Rotation"
  • Lock-on slide switch for continuous operation ("Hammering Only" mode)
