Hilti SF 8M-22 Cordless impact wrench

Cordless drill/driver with interchangeable chucks, increased torque, higher RPM and adjustable speed Maximum torque (soft/hard clutch): 55 Nm (soft clutch), 75 Nm (hard clutch) No-load speed, revolutions per minute: speed 1: 365 rpm; speed 2: 625 rpm; speed 3: 1440 rpm; speed 4: 2460 rpm Spindle opening range: 2–13 mm Features Greater flexibility and productivity thanks to interchangeable chucks: the innovative chuck design allows chucks (M3–M16 taps, self-locking chucks, universal chucks) to be changed quickly in a matter of seconds Improved performance on metal: the high RPM of 2,460, combined with the smooth torque (60 Nm) and four speeds, enables this cordless drill/driver to handle complex cordless metal drilling and screwdriving applications with ease Greater peace of mind: a special chuck with an ‘auto-lock’ function, designed to prevent the bit from slipping during metal drilling applications Safer working environment: Hilti’s Active Torque Control (ATC) system prevents the tool body from rotating uncontrollably should the bit become jammed, whilst the LED light in the base provides a clear view of the work area Enhanced performance: the powerful battery and brushless motor offer greater runtime and longer drilling and screwdriving times at high, constant speeds Applications Drilling into metal with HSS drill bits up to 20 mm in diameter Drilling metal sheets up to 3 mm thick with step drill bits up to 40 mm in diameter Drilling holes in metal using hole saws up to 102 mm Tapping up to M16 (suitable for square-shank taps with threaded chucks) Countersinking in metal with diameters up to 31 mm
