POWERFUL MOTOR: 1200W industrial motor with 4.5J impact energy is designed to complete heavy duty concrete and metal working projects with ease and precision. Heat resistant copper wire motor allows long working time without burning the machine. Anti-dust bottom structure extend the hammer's use life.
HUMANIZATION DESIGN: Safety clutch protection designed to guarantee your wrist When the hammer is subjected to high torque force. 360° adjustable handle applies to different work and the upgraded double layer anti-vibration system designed to decrease the vibration effectively, and reduce fatigue. The PU soft grip handle effectively prevents sliding and brings a better and comfortable holding during use.
THREE FUNCTIONS: Three different functions of drilling(suitable for wood, steel , etc.), chiseling(suitable for concrete or brick) and hammer drilling(suitable for heavy duty work) function adapt to variety of work scenarios which are easy to switch. You can quickly switch the functions by two different switches. Compared with single function switch design, the double function switch design can extend 100% service life.
DRILLING CAPACITY: The max drilling diameter for concrete is 28mm and for metal is 13mm. This rotary hammer drill can reach 900 r/min no-load speed and 4300bpm max impact frequency.
