MAKITA® AVT® Rotary Hammer Has Lowest Vibration in Its Class
Press release date: March 10, 2014
New HR4013C with enhanced AVT® delivers faster drilling with less vibration
La Mirada, CA — Makita has expanded its line-up of concrete hammers with a new 1-9/16” AVT® Rotary Hammer that has 45% less vibration and 20% more impact energy than the previous model. The new HR4013C is engineered with enhanced Anti-Vibration Technology (AVT®), a synchronized three-component system for significantly less vibration. The result of the enhanced AVT® is a category-leading vibration rating of 5m/s².
“In the development of new tools, Makita engineers focus not only on power and specs, but also on the end-user’s comfort when using the tools,” said Adam Livingston, Product Manager, Commercial Products, Makita USA. “The new HR4013C with enhanced Anti-Vibration Technology gives concrete contractors the lowest vibration in the 1-9/16” category, while at the same time delivering 20% more impact energy for all-day industrial applications. This is a remarkable engineering achievement, and a great solution for contractors.”
Enhanced Anti-Vibration Technology
Makita AVT® is an internal counterbalance system that greatly reduces vibration for increased user comfort and greater efficiency. The HR4013C features an enhancement to this already innovative technology with a new synchronized three-component system:
• An Air Actuated Counterbalance directs air pressure from the crank and barrel room into the counterbalance cylinders to move counterweight pistons in the opposite direction of the drive piston, which actively reduces vibration.
• A Vibration-Absorbing Housing features a spring-loaded main handle and upper housing that move independently of the motor and drive mechanism, engineered to isolate vibration away from the user.
• An Integrated Damper Spring at the base of the impact bolt is engineered to absorb impact vibrations from the drill bit.
"Many rotary hammers have a spring-loaded handle as their primary means of reducing vibration,” said Livingston. “This enhanced three-component AVT® system is advanced technology that is engineered inside the tool. This new AVT® is superior to simple one-component systems, so users get substantial vibration reduction.”
More Power, Less Vibration
The new HR4013C 1-9/16” AVT® Rotary Hammer has the lowest vibration in its class at only 5m/s². The powerful 11 AMP motor delivers 11.4 Joules (8.4 ft. lbs.) of impact energy, 20% more than the previous model for faster drilling. An added feature is the option of lock-on or trigger-activated in the “chipping only” mode, with a push button start/stop control for more convenient operation.
Additional features include constant speed control that automatically applies additional power to the motor to maintain speed under load, soft start for more control and greater accuracy, and a torque-limiting clutch. The HR4013C offers 2-mode operation for “chipping only” or “hammering with rotation”, as well as 24 bit angle settings and a one-touch sliding chuck for quick bit changes.
Ideal for Range of Concrete Applications
The new HR4013C is engineered for a range of concrete applications including drilling/coring through-holes for pipes, setting larger anchors, securing tilt-wall supports, small chipping applications, and more. It is ideal for a range of trades including masons, concrete contractors, demolition contractors, plumbers, electricians, sprinkler installers, and general contractors seeking a best-in-class rotary hammer.
