Product Information:

The HR4511C Rotary Hammer Machine, 45mm, Powered by a Powerful 1,350W Motor, provides 2,750 rpm. This Rotary Hammer Machine features 2-operation modes, which can be used as a rotary hammer or a hammer only. An Ergonomically designed handle with a rubberized soft grip provides more control and comfort. In addition, double insulated to protect the user, Variable speed allows the user to control the speed. With a 70% vibration reduction technology, Soft Start ensures smooth starting and constant speed control, and the dust collecting system helps provide a cleaner work environment and ensures reliability and long life. Powerful Features: Anti-Vibration Technology: Anti-vibration technology is an internal counterbalance system that greatly reduces vibration with 70% vibration reduction technology, we know from experience that the larger the power tool, the harder it is to control it while working. Now, thanks to the AVT system, working with a hammer or demolition hammer has become much easier and does not require such a strong hand of the user. Double insulation: Double or reinforced insulation is another method of protection against electric shock, consisting of an extra layer of supplementary insulation over the basic insulation, or the live parts. Double insulation devices protect the user through two independent isolation systems. These systems protect electric motor components from the outer motor housing and tool holding areas. Variable speed: Variable speed control allows the user to match the speed to the application they are working on. Torque Limiter: Torque limiter is a built-in clutch reduces gear damage by disengaging gears if the bit binds. Constant Speed: Constant speed control automatically applies additional power to the motor to maintain speed under load. Soft Start: Soft start prevents start-up reaction to ensure smooth starting, longer gear life and better accuracy when starting work. Dust Collecting: The dust collector is designed to reduce the amount of dust produced during cutting and concrete dust generated during drilling on the job site, allowing you to work efficiently and comfortably. Makita Rotary Hammer Machine Features: High performance and low vibration. (with Vibration absorbing grip) 2 operation modes - hammering and hammering with rotation. AVT (Anti-Vibration Technology) Active Dynamic Vibration Absorber ensures extra-low vibration performance. One-Touch Sliding Chuck enables easy bit change.
