Feature●1-9/16-in Rotary Hammer Drill●MOTOR: 11. 3 Amp motor and 1150 watts of input power for increased productivity●LOW VIBRATION: UVP (User Vibration Protection) technology greatly reduces vibration for comfortable extended use and fewer vibration related injuries via the use of internal counterweights and springs, as well as low vibration handles●BODY: AHB (Aluminum Housing Body) construction significantly enhances the internal and external durability of the tool●SPEED SELECTOR: Four power levels of impact and rotation speed to match the application●TRIGGER: Large trigger switch for easy grip and better control●CHANGE LEVER: Located on top of tool for easy access - rotates for hammer drilling or hammer only with a neutral position for transitionsDescription The Rotary Hammer (DH40MEY) with AC Brushless Motor, UVP (User Vibration Protection) and AHB (Aluminum Housing Body) is the perfect combination of performance and comfort. With top class drilling speed along with UVP, this hammer is made for hard work. It features the AHB construction that provides significant durability and extended tool life. The Brushless Motor allows the tool to operate over an extra long extension cord with reduced power loss, and also eliminates maintenance of armatures or carbon brushes. This rotary hammer delivers superior performance when powered by a generator due to an internal inverter circuit that regulates uneven power supply for ultimate jobsite convenience.
