30 mm (1-3/16″) 3.9 J Combination Hammer, SDS-PLUS Bits

• Drilling efficiency drastically increased by redesigned hammering mechanism
• 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
• 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
