The hr007g is a brushless rotary hammer, adapted for sds plus bits, powered by a 40v max li-ion xgt slide type battery. It features variable speed controlled by trigger to enable the user to match the speed to the application and constant speed control to automatically apply additional power to the motor to maintain constant speed under load. Features & benefits 3 mode operation: rotation only, rotation hammering, hammering only active feedback sensing technology shuts down tool if rotation speed suddenly slows down anti vibration housing and avt for reduced operator fatigue auto start wireless system connects to compatible dust extractors with bluetooth brushless motor constant speed control electric brake electric brake led job light reversing switch the dust extractor automatically runs while the switch is on torque limiter trigger lock variable speed specifications battery voltage: 40v max battery type: xgt lithium ion blows per minute: 0-5,000bpm impact energy: 3.0J max.
