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]
The Makita 1” AVT® Rotary Hammer with HEPA Dust Extractor (model HR2661, with D-Handle) is a total solution that combines efficient drilling and chipping with reduced vibration and improved dust extraction. The HR2661 is engineered with Anti-Vibration Technology (AVT®), an internal counterbalance system for significantly less vibration. It has a built-on dust extractor that captures concrete dust during drilling. The HR2661 combines these performance features in a compact size. It is ideal for a range of applications including overhead drilling into concrete, wood and metal, removing tile, and more.
The HR2661 has an 8 AMP motor that delivers 2.2 Joules (1.6 ft.lbs.) of impact energy to handle the most demanding applications. The 3-mode operation offers “rotation only”, “hammering with rotation” or “chipping only” for multiple applications. Modes can be easily changed with a recessed hammer-function selector, which is located below the gear housing for improved durability. The ergonomic D-shaped handle with a rubberized soft grip provides increased operator comfort, as well as a retractable tool hook to secure the tool to studs, ladders, and rails when not in use.
The dust extractor is activated by the tool for operator convenience and is equipped with an efficient HEPA filtration system that captures 99.97% of particulates .3 microns and larger. It has a transparent dust container with an accurate level indicator of collected material for added convenience.
