What it is
The DeWalt DCF850P2T-QW compact impact driver from the XR 18 V range with a 1/4" hex drive offers 3 speed modes to match power to the type of fastening. It delivers a maximum torque of 205 Nm and an output power of 475 W, with a speed of up to 3250 rpm and an impact frequency of up to 3800 blows/min. At only 101 mm long and weighing 0.9 Kg, it is compact and powerful; the kit includes two 5 Ah batteries, an LED light and CE marking.
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, for assembly work 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.
