Extremely powerful battery-powered three-speed impact drill from the Flexvolt Advantage series: For a double advantage when using XR Flexvolt instead of common 18 Volt XR batteries: 1.) Due to the lower internal resistance of the battery cells, the current flow to the motor is faster, so that even when using an XR Flexvolt battery with 6 Ah, the motor delivers over 54% more output power and thus a correspondingly stronger pulling force. 2.) Much longer running time due to the provision of very high battery capacities of up to 12 Ah. Over 50% longer runtime per battery charge as well as longer service life due to innovative, brushless motor technology. Robust 13 mm full metal quick-action drill chuck and automatic spindle lock. Very high work progress due to optimally matched 3-speed full metal gearbox. Innovative, electronic torque clutch as well as precise 11-stage torque module with reliable cut-off torque. Innovative three-stage LED light with very high luminosity of up to 77 lumens and optimally aligned light cone. Electronic rotation and impact speed regulation as well as clockwise / anticlockwise rotation. Standard in T STAK box and as basic type (without batteries and charger) optimally suitable for already existing 18 Volt XR or XR Flexvolt batteries or for the Dewalt 'Akku Plus' system.
