The 1" AVT rotary hammer (model HR2641, with D-Handle) is engineered with Anti-Vibration Technology (AVT), an internal counterbalance system for significantly less vibration. The HR2641 combines performance and power with less vibration in a compact size, and is ideal for a range of applications including overhead drilling.
The HR2641 has an 8 AMP motor that delivers 2.9 Joules (2.1 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 HR2641 is engineered for a range of applications including overhead drilling into concrete, wood and metal, removing tile, and more. It is ideal for a range of trades including masons, plumbers, electricians, sprinkler installers, city maintenance crews, and general contractors seeking a best-in-class 1" rotary hammer.
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.
Features:
• Powerful 8 AMP motor delivers 2.1 ft.lbs./2.9 J. of impact energy to handle the most demanding applications
• Anti-Vibration Technology (AVT) is an internal counterbalance system that greatly reduces vibration by moving a counterweight in the opposite direction of the drive piston
• Integrated damper spring at the base of the impact bolt is engineered to absorb impact vibrations from the drill bit
• Recessed hammer function selector located below gear housing for improved durability
• Torque limiting clutch engineered to prevent gear damage by automatically disengaging gears if the bit binds
• Variable speed trigger enables user to match the speed to the application for greater versatility
• 3-mode operation for "Rotation Only", "Hammering with Rotation" or "Chipping" for multiple applications
• 40 bit angle settings allow the bit to be set at different positions for operating convenience
• Ergonomic "D-shaped" handle with rubberized soft grip for increased comfort
• Retractable hook allows tool to remain close by but never in the way
• Sequential impact timing delivers timed hammering during rotation to minimize overlapping bit impacts for up to 50% faster drilling
Includes:
• (1) Side Handle (451749-9)
• (1) Depth Gauge (331886-4)
• (1) Tool Case (824695-3)
