Makita 1-9/16" Advanced AVT Rotary Hammer, accepts SDS-MAX bits, 2-mode, var. spd., case. Manufacturer's Product Number: MK-HR4013C.

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 powerful 11 AMP motor delivers 8.4 ft. lbs. (11.4 Joules) 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.

Features

• 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 vibration
• 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
• Constant speed control automatically applies additional power to the motor to maintain speed under load to complete the most challenging jobs
• Soft start suppresses start-up reaction for more precision and better accuracy
• "Soft no-load" function automatically reduces the speed of the motor when idling to help increase tool life and performance
• Variable speed control dial enables user to match the speed to the application for greater versatility
• Torque limiting clutch engineered to prevent gear damage by automatically disengaging gears if the bit binds

WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.
