TECHNICAL DATA: Mounting type: 1/2" square Max. idle speed: 0 - 2000 rpm, Speed at 1st idle speed: 0-600 rpm, Speed at 2nd idle speed: 0-1200 rpm, Speed at 3rd idle speed: 0-2000 rpm, Max. impact rate at idle speed: 0 - 3250 bpm Impact rate at 1st idle speed: 0 - 975 bpm Impact rate at 2nd idle speed: 0 - 1950 bpm Impact rate at 3rd idle speed: 0 - 3250 bpm Maximum torque: 812 Nm Torque at 1st gear: 136 Nm, Torque at 1st gear: 405 Nm, Torque in 1st gear: 812 Nm, Maximum breakaway torque: 1084 Nm, Overall length with head: 175 mm. Weight (EPTA): 1.67 kg CORDLESS 1/2' XR 18V 0 AH IMPACT WRENCH TSTAK Equipped with a high-power brushless motor with up to 812 Nm of torque, 1084 Nm of breakaway torque, Brushless motor thanks to less friction, it has less energy loss - it can work longer on one battery charge and has a much longer service life, The DCF891 wrench offers 4 operating modes, and the force is adjusted using the trigger: "screw symbol" is a mode for precise tightening/loosening of screws, the wrench tightens at maximum speed until it encounters resistance, stops for a short moment and starts tightening sequentially (several strokes / pause) for better control of the tightening force, when loosening, the wrench works with full force until it is unscrewed, and after loosening it reduces the speed to prevent uncontrolled shedding of the nut / bolt, "1" is the first gear, at which the wrench tightens at low speed to 600 rpm (136Nm), unscrews at full speed 2000 rpm, "2" is the second gear, at which the wrench tightens at medium speed to 1200 rpm (406Nm), unscrews at full speed 2000 rpm, "3" is the third gear, at which the wrench tightens at high speed to 2000 rpm (812Nm), unscrews at full speed 2000 rpm, A powerful LED in the foot with a dimming function ensures very good visibility of the work field, It has a rubberized, non-slip handle, A special hook allows you to attach the key to your belt.
