Model: Makita HR3011FCJ
30mm (1-3/16") AVT Combination Hammer SDS Plus 1050W
FEATURES:
- Drilling efficiency drastically increased by redesigned hammering mechanism
- Anti-Vibration Technology (AVT) for low vibration
- Powerful yet with low vibration due to 2 Counterweights, Anti-vibration rear handle and Anti-vibration side grip yet maintaining high power
- Anti-vibration side grip absorbs excess vibration beyond the canceling capacity of the two counterweights
- Anti-vibration rear handle; Vibration absorbing performance is increased by two cushion rings added to connecting parts
- Less bit wobbling achieved by making bit guide portion 8 mm longer than that of HR2811F series
- Powerful 1,050 W motor delivers 3.9 J (EPTA-Procedure 05/2009) of impact energy to handle the most demanding applications
- LED light illuminates drilling surface for more productivity in low light applications
- 3-mode operation for “Rotation Only”, “Hammering with Rotation” or “Hammering Only”
- “No hammering when idling” function helps increase tool life
- Torque limiting clutch engineered to minimize gear damage by automatically disengaging gears if the bit binds
- Ergonomic “D-shaped” handle with rubberized soft grip for increased comfort
- Variable speed control dial allows operator to adjust speed based on materials or application
- Constant speed control automatically applies additional power to the motor to maintain speed under load
- Recessed lock-on button for continuous operation
- Depth gauge for increased drilling consistency
- Double insulated
INCLUDES:
