Vibration Takes Another Hit as Makita 2 Inch AVT Rotary Hammer Enters the Market
Makita continues its assault on vibration with the new Makita 2 Inch AVT Rotary Hammer. The latest tool in the AVT lineup features Makita’s enhanced Anti-Vibration Technology. This consists of three components working together to reduce vibration by as much as 89% compared to the previous model. The air-actuated counterbalance redirects air to move the counterbalance in the opposite direction of the piston. The Vibration Absorbing Housing allows the handles to move independently of the motor, isolating vibration away from the user. An Integrated Damper Spring helps to reduce the vibration transmitted from the bit itself.
According to Adam Livingston, Product Manager, Commercial Products, Makita USA, “Many rotary hammers have a detached, spring-loaded handle as their primary means of reducing vibration, which appears to be just an update to an existing tool having limited effect on vibration reduction. Compare this to our three-component AVT system, which utilizes advanced technology as part of the overall engineering of the tool, isolating vibration not only at the rear handle but also at the side handle, an industry first. The result is industrial performance with significantly less vibration.”
Even with reducing the vibration to 9 m/s², it still packs a punch by delivering 14 foot pounds (19 joules) of impact energy to the bit. There is also a soft start to improve control, as well as an optional lock on while in chipping mode. One feature that I really like on the Makita 2 Inch AVT Rotary Hammer is the constant speed control. This feature provides additional power during operation to maintain the selected speed. Two modes are available on the new AVT Rotary Hammer: Chipping Only and Hammering with Rotation. You’ll also find 24-bit angle settings and a one-touch sliding chuck.
