What it is
The M18 FUEL ONE-KEY impact wrench with ½″ square P drive is intended for professional use in the following contexts:
An impact driver or wrench is a cordless, corded or pneumatic tool that drives and removes screws and bolts with rotary impacts, with a hex drive for bits or a square drive for sockets.
What it is for
Used for repetitive screwdriving into wood, metal and plasterboard, where torque and consistency matter, for vehicle maintenance, in the workshop and on the road and for tightening nuts and bolts where torque must be accurate and repeatable.
How to use it
Fit an impact-rated bit or socket suited to the drive and select the mode or power setting. Start the screw or nut, hold the tool in line and release the trigger when the part is seated, to avoid damaging threads and heads. For tightening to a specified torque, finish with a torque wrench; pneumatic models must be supplied with filtered, lubricated air.
