MAKITA HR4003C 40 mm 8.3 J Rotary Hammer SDS-MAX Bits

MAKITA HR4003C 40 mm 8.3 J Rotary Hammer SDS-MAX Bits,

• Powerful 1,100 W motor delivers 8.3 J of impact energy to handle the most demanding applications
• Lock-on or trigger activation in “Chipping Only” mode with a push button start/stop control
• 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 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
• Depth gauge for increased drilling consistency
