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.
