- Powerful 850 W motor delivers 5.1 J (EPTA-Procedure 05/2009) 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
- Variable speed control dial enables the user to match the speed to the application for greater versatility
- LED 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 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
- 3-Mode operation for “Rotation Only”, “Hammering with Rotation” or “Hammering Only” for multiple applications
- 24 Bit angle settings allow the bit to be set at different positions for operating convenience
- One-touch sliding chuck allows for quick bit changes
- Lock-on switch for continuous operation (“Hammering Only” mode)
- Ergonomically designed handle with rubberized soft grip provides more control and 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
- Depth gauge for increased drilling consistency
- Double insulated
