Constant speed control automatically applies additional power to the motor to maintain speed under load to complete the most challenging jobs. Twin LED lights with preglow and afterglow functions for better illumination. Powered by 2 x 40v Batteries Active feedback sensing technology (AFT) turns the motor off it bit rotation is suddenly forced to stop Anti-vibration technology (AVT) is a synchronised, three-component system that more effectively reduces vibration Auto-start wireless system (AWS) connects to compatible vacuum cleaners with Bluetooth Twin LED lights with pre-glow and afterglow functions for better illumination and more accurate work Extreme protection technology (XPT) is engineered for improved dust and water resistance for operation in harsh conditions Depth gauge for increased drilling consistency Torque limiting clutch engineered to minimise gear damage by automatically disengaging gears if the bit binds Battery protection No load speed 150 - 310 min Impacts per
