What it is
Impact driver 18V - Unita' Without battery (FMC645B) (FMC645B) Stanley. Key specifications: charging time (min) 40, chuck capacity (mm) 6,35, blows per minute 3100.
A hex-drive impact driver is a cordless driver that, under load, delivers rotary impacts to drive long screws and bolts without twisting the wrist.
What it is for
Used for repetitive screwdriving into wood, metal and plasterboard, where torque and consistency matter and for tightening nuts and bolts where torque must be accurate and repeatable.
How to use it
Insert an impact-rated bit, tougher than standard bits, into the drive and select the mode or speed suited to the job. Hold the tool in line with the screw and release the trigger as soon as the head is seated, to avoid stripping or snapping the screw. Where a precise torque is required, complete the tightening with a torque wrench.
