Makita HR3011FCJ SDS-Plus Rotary Hammer / Combination Hammer

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
