Description
Features: Powered by an 850watt motor and generating 6.4 joules of impact energy and with up to 3,300 blows per minute available, the new Makita HR3210C AVT will punch a 32mm hole into concrete and drive a 90mm CT core cutter This 3-function machine provides rotary-only operation for drilling with a no-load speed of between 315 and 630rpm Rotary action with hammer support can be selected as can pure hammer-only action for heavy-duty breaking and demolition work The HR3210C has variable speed control and is fitted with a torque limiter device that instantly disengages the drive should the drill bit or core snag during operation This action protects both the operator from physical injury and the machine from mechanical and electrical overload Two unique Makita features contribute to the super-safe, low vibration benefits of this new, advanced machine The patented Makita, AVT Anti Vibration Technology system uses the pneumatic pressure generated in the hammer piston chamber to move a counterbalance in the opposite direction to dampen out the impact vibrations at the steel point This dramatically reduces machine produced vibrations. In addition to the advanced AVT system, this new Makita 5kg hammer features the 2-Mass fulcrum hinged rear grip handle and the vibration-damping side handle to further limit HAV risks Torque limiter: The drill stops when the bit hits against reinforcements. Soft start Constant speed under load Built-in job light Comes with: Side handle Depth stop Bit grease Carry case Specification: Impact energy: 5.0 J Max in concrete: 32 mm Impacts per minute: 1650 - 3300 ipm Input Wattage: 850 w Max core diameter (TCT): 90 mm Vibration K factor: 1.5 m/sec² Net weight: 5.2 - 5.6 kg No Load Speed: 315 - 630 rpm Vibration: Drilling: 2.5 m/sec² Vibration: Chiselling: 7 m/sec² Vibration: Hammer Drilling: 10 m/sec² Noise sound pressure: 89 dB(A) Noise K factor: 3 dB(A) Noise sound power: 100 dB(A)
