The vibration absorbing housing offers unrivalled low level of vibration. In hammering mode, the on/off switch is switchable between two switches to meet your application, for Continuous or Intermittent chiselling applications. Advanced Anti-Vibration Technology (AVT®) is a synchronized, three-component system that more effectively reduces vibration resulting in a low 5m/s2 Soft no load" function automatically reduces the motor speed during idling to suppress the vibration of the machine body The soft no load function automatically reduces the motor speed during idling to suppress the vibration of the machine body. There is a handy LED service light indicating when to replace carbon brush, preventing additional damage to the gearings.

The 1-9/16” AVT® Rotary Hammer (model HR4013C) has 45% less vibration and 20% more impact energy than the previous model. It 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.The Makita HR4013C’s 11-amp motor has up to 8.4 foot-pounds of impact energy. Weighing just over fifteen pounds, it sports a maximum concrete drilling capacity of 1-9/16 inch. The new Makita HR4013C SDS max rotary hammer will punch a 40mm hole in concrete and with a 1,000 watt motor that will run up to 500rpm without load, this machine will generate up to 2,900 blows per minute for 7.6 Joules of impact energy. This represents a 25% increase over the popular HR4011C model that it supersedes. As mentioned above, the AVT, or anti-vibration technology, helps reduce user fatigue when you’re working on very difficult tasks for long periods of time. Easy to operate operation-mode change lever, located on the top of the motor housing for reduced possibility of breakage In hammering mode, on/off switch is switchable between two switches to meet your application, for continuous or intermittent chiselling applications

Variable speed control dial enables user to match the speed to the application for greater versatility Constant speed control automatically applies additional power to the motor to maintain speed under load to complete the most challenging jobs Vibration absorbing housing features a spring loaded main handle and upper housing that move independently of the motor and drive mechanism efffectively isolating most of the vibration away from the user Because Makita is a well-known tool brand, they are reliable when it comes to warranty policies and unit care. So you might want to try this rotary hammer if you’ve gone through cheaper hammers that didn’t live to your expectations in terms of power. Makita's Latest AVT 40mm SDS MAX Rotary Hammer Allows 8-Hour Working The latest version of Makita’s popular 40mm AVT rotary hammer drill delivers a massive 25% increase in impact power with an even larger 30% reduction in vibration rating. Impact energy of the new Makita HR4013C is increased to 7.6 Joules whilst the vibration rating in hammer-only action is ultra-low at 4.5m/sec² and in rotary hammer drilling mode an equally impressive 5.0m/sec².

Support

The tool weighs 15.1 pounds, but it should be noted that the majority of the heavy-duty and standard-sized rotary hammers out there weigh about the same. However, if you are a beginner or one who prefers lightweight tools, this might be on the heavier side for you. Without proper ventilation, you may sense a factory-like smell.
