MAKITA HR2810 28 mm (1-1/8″) 2.8 J Combination Hammer SDS-PLUS Bits

MAKITA HR2810 28 mm (1-1/8″) 2.8 J Combination Hammer SDS-PLUS Bits,

• Torque Limiting Clutch Engineered to Prevent Gear Damage
• Powerful 800 W motor delivers 2.9 J (EPTA-Procedure 05/2009) of impact energy to handle the most demanding applications
• 3 operation modes – hammering, hammering with rotation, rotation
• “No hammering when idling” function helps increase tool life
• Sequential impact timing delivers timed hammering during rotation to minimize overlapping bit impacts for up to 50% faster drilling
• Torque limiting clutch engineered to prevent gear damage by automatically disengaging gears if the bit binds
• Ergonomic “D-shaped” handle with rubberized soft grip for increased comfort
• Recessed lock-on button for continuous operation
• Extended life brushes for more work between service intervals and less downtime
