Description of Makita HR4013C 1 9 Rotary Hammer

Powerful 11 AMP motor delivers 8.4 ft.lbs. / 11.4 J. of impact energy to handle the most demanding applications. Advanced Anti-Vibration Technology (AVT) is a synchronized, three-component system that more effectively reduces vibration resulting in a low 5m/s2. Advanced AVT includes an air actuated counterbalance that directs air pressure from the crank and barrel room into the counterbalance cylinders to move counterweight pistons in the opposite direction of the hammer mechanism to effectively reduce vibratio. Advanced AVT includes a vibration absorbing housing with a spring loaded back handle and housing which moves independently of the motor and hammer mechanism effectively isolating more vibration away from the user. Advanced AVT includes an integrated damper spring at the base of the impact bolt engineered to absorb impact vibrations from the drill bit. Anti-Vibration Technology (AVT) is a Synchronized, Three-Component System that more Effectively Reduces Vibration Resulting in a Low 5m/s2. Anti-Vibration Technology (AVT) is an Internal Counterbalance System that Greatly Reduces Vibration. Vibration Absorbing Housing Features a Spring Loaded Main Handle and Upper Housing that Move Independently of the Motor and Drive Mechanism. Integrated Damper Spring at the Base of the Impact Bolt is Engineered to Absorb Impact Vibrations from the Drill Bit. Powerful 11 AMP Motor Delivers 8.4 ft. lbs. of Impact Energy to Handle the Most Demanding Applications.

Surprisingly disappointed

I received this rock drill and used it for less than 15 minutes before it stopped working. This stopped the hammer blows and made the motor sound like an old cordless tool when it ran out of power. It didn't smoke or give off a strong odor, so I left the tool on for about an hour and it started working again. After about 30 seconds of running, he did the same thing again. I wasn't leaning heavily on the tool or trying to make it work. This is one of the Makita tools made in Japan and I expected

Pros
  • Anti-Vibration Technology (AVT) - an internal balancing system that greatly reduces vibration
Cons
  • Doubtful

Professional quality at a very reasonable price

UPDATE AUGUST 2020: I'll probably smooth it out, but this machine still works. I use it for almost everything, a few times a month, floor cleaning, concrete drilling, chiseling, all types of demolition work where a heavier machine wouldn't fit, and even digging. I couldn't have dreamed of a better car. It's the perfect combination of weight and performance, at least for digging. I used it to dig over 200 linear feet of a 24" deep, 24" wide trench in medium density clay/disintegrated granite…

Pros
  • Built-in dampening spring at the base of the firing pin is designed to absorb impact vibration from the drill
Cons
  • Crumpled

Excellent performance; very poor outgassing

I bought it mainly as a demo hammer. It is very comfortable to use and has a good power to weight ratio. I am very happy with the performance. I've owned five different demo and/or rock drill bits and this one is by far my favorite. The only thing I complain about is the outgassing. I've had this hammer drill for about six months and it still reeks of an awkward chemical odor when I open the case. Upon closer inspection, it turns out that the smell comes from softer plastics - cord, handle…

Pros
  • Anti-Vibration Technology (AVT) is a synchronized 3 piece system that reduces vibration more effectively resulting in speed reductions of up to 5m/s2
Cons
  • Questionable purchase for the elderly
