Wera 851/855/1 PH 21 Piece Impaktor Phillips and Pozi Screwdriver Bit Set
The Wera 851/855/1 PH 21 Piece Impaktor Phillips and Pozi Screwdriver Bit Set is a professional-grade impact bit set designed for contractors and tradespeople who rely on impact drivers for high-volume screwdriving tasks.
The set features Wera's Impaktor technology, which is engineered to withstand the extreme impulse peaks generated by impact drivers — dramatically extending bit service life compared to standard screwdriver bits. A rough diamond-particle coating on each bit tip bites into the screw head to enhance friction and prevent cam-out, keeping work moving efficiently even under demanding site conditions.
The included Wera 897/4IMP R Impaktor holder adds further versatility, incorporating a double-torsion spring to absorb shock and a retaining magnet to hold long or heavy screws securely in position. This makes it particularly practical for overhead work or awkward fixing angles. Should the magnet be unwanted — for example when working with metal — it can be repositioned away from the screwdriving zone and neutralised.
All bits feature a 1/4" hexagon shank, compatible with standard power screwdrivers and impact drivers with a 1/4" drive as per DIN ISO 1173.
