Friday, October 31, 2014

The new The new HR5212C delivers a full 19 Joules of impact energy for industrial applications.

The vibration-absorbing housing is engineered to isolate the rear handle and side handle – an industry first.

This cut-away view clearly shows that Makita’s Anti-Vibration Technology is engineered inside the tool. The result is more effective vibration reduction, without compromising tool performance.

MAKITA EXPANDS AVT LINE-UP WITH NEW 2-INCH ROTARY HAMMER

HR5212C with enhanced AVT delivers faster drilling with significantly less vibration

La Mirada, CA – La Mirada, CA – Makita® has expanded its line-up of concrete hammers with a new 2″ AVT® Rotary Hammer that has up to 89% less vibration than the previous model, but with no compromise in impact energy. The new HR5212C is engineered with enhanced Anti-Vibration Technology (AVT®), a synchronized three-component system for significantly less vibration that results in a vibration rating of only 9m/s².

Greater Comfort and Standard-Setting Performance
“In the development of new hammers, Makita engineers focus on user comfort first in both design and functionality. Amazingly, they continue to set new standards in power and performance, as well,” said Adam Livingston, Product Manager, Commercial Products, Makita USA. “The recently-released HR4013C with the same enhanced Anti-Vibration Technology gave contractors the lowest vibration 1-9/16″ rotary hammer, and now the new HR5212C has one of the lowest vibration ratings in the 2″ concrete drilling category.”
Enhanced Anti-Vibration Technology
Makita AVT® is an internal counterbalance system that greatly reduces vibration for increased user comfort and greater efficiency. The HR5212C features an enhancement to this already innovative technology with the new synchronized three-component system:
  • 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.
  • 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. This vibration-absorbing housing effectively isolates the rear handle and side handle – an industry first.
  • 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 detached, spring-loaded handle as their primary means of reducing vibration, which appear to be just updates to an existing tool having limited effect on vibration reduction,” said Livingston. “Compare this to our three-component AVT® system, which is advanced technology that is part of the overall engineering of the tool, isolating vibration not only at the rear handle but also at the side handle as well, an industry first. The result is industrial performance with significantly less vibration.”
More Power, Less Vibration
The new HR5212C 2″ AVT® Rotary Hammer has one the lowest vibration ratings in its class at only 9m/s². The powerful 5 AMP motor delivers 19 Joules (14 ft. lbs.) of impact energy 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 right in front of the rear handle for more convenient operation.
Additional features include soft start for more control and greater accuracy, a torque-limiting clutch, and constant speed control that automatically applies additional power to the motor to maintain speed under load. The HR5212C 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 HR5212C 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.
