Makita is adding the new HR4013C AVT Rotary Hammer to its Anti-Vibration Technology lineup. This 1-9/16″ rotary hammer boasts up to 45% less vibration while delivering up to 20% more impact energy than previous models. Makita AVT technology reduces vibration by utilizing a counterweight that counteracts the force of each hammer blow. It’s a solution that has been utilized for years in other tools, but larger demo hammers are now coming online that feel significantly smoother than anything previously used by professionals.
Build Quality and Features
We checked out the new Makita 2-inch AVT Rotary Hammer, which utilizes AVT technology, and this seems like something we’ll see more of in the future. Makita’s Anti-Vibration Technology (AVT) has been enhanced in the HR4013C to create a three-part system. The air-actuated counterbalance utilizes the air pressure generated by the tool to move the counterbalance pistons in the opposite direction of the drive pistons. The Vibration Absorbing Housing is designed to utilize a spring-loaded handle and upper housing that move independently of the gearing and motor to absorb vibration. Finally, the Integrated Damper Spring, located at the base of the impact bolt, absorbs vibration from the drill bit. To check out AVT on a large scale, look no further than the company’s 17 lb. AVT Demolition Hammer (HM1111C)
The AVT Rotary Hammer features an 11-amp motor that delivers 11.4 J of impact energy and a range of 1450-2900 blows per minute, controlled by the variable speed trigger. It accepts Makita’s SDS-Max bits and has been engineered for a variety of concrete applications.
