Tough on concrete, not on you: Makita’s hard-hitting HR4510C 1-3/4” SDS-MAX Rotary Hammer is equipped with Anti-Vibration Technology (AVT), an exclusive counterbalance system that reduces vibration. The result is more efficient hitting on the concrete and less vibration in the tool – and the tool user.
13.5 AMP Power with 2-Mode Operation
The HR4510C with AVT® is engineered with a 13.5 AMP motor that delivers a no load speed of 130 to 280 RPM and 1,250 to 2,750 BPM. The synchronized RPM and BPM prevent overlapping impacts for up to 50% more efficient drilling. The hammer features 2-mode operation: “hammering with rotation” and “hammering only,” with a built-in torque limiter that ensures stable torque control and disengages the motor should the bit bind or hit reinforcements. In addition, the electronic speed control reduces speed loss when working in heavy applications to ensure maximum productivity.
The HR4510C also has a variable speed dial with 5 settings to match the bit speed to the application. An L.E.D. power light indicates switch failure or cord breakage, and an L.E.D. service light indicates when carbon brushes need to be replaced. The HR4510C is built with large size carbon brushes that have up to twice the life of competitor models.
More Work, Less Vibration
The HR4510C is equipped with AVT, Makita’s exclusive counterbalance system that reduces vibration for more efficient hitting power. The HR4510C weighs 20.1 lbs. and has two options of side handles available (straight and D-shaped, both with rubberized grips), and a large rubberized rear handle, all of which contribute to the overall comfort of the tool. The recessed operation mode switch helps prevent it from being damaged, while the one-touch sliding chuck allows for quick bit changes.
Versatile Design for a Range of Applications
The HR4510C is a versatile, hard-hitting rotary hammer for masons, remodelers, electricians, plumbers, demolition contractors, and general contractors seeking a best-in-class industrial quality rotary hammer. The tool is built for drilling large anchor holes and breaking concrete and other masonry materials.
Anti-Vibration Technology (AVT®) is a counterbalance system inside the tool that significantly reduces vibration. The AVT® counterbalance design is based on seismic engineering, which developed this damping science to absorb shocks and protect buildings from earthquakes. AVT® uses a mechanical damper, effectively a counterbalance weight inside the tool, that provides an equal and opposite force that puts a mass directly opposite the point where the striker bolt delivers the impact. As vibration is eliminated, power is efficiently increased which allows more of the generated energy in the motor to be delivered to the tool bit. Makita also has an AVT® counterbalance system in select recipro saws. For users, AVT® means significantly less vibration with no compromise in power and performance. [Learn More]
