Wera 855/1 PZ 21 Piece Impaktor Pozi Screwdriver Bit Set

The Wera 855/1 PZ 21 Piece Impaktor Pozi Screwdriver Bit Set is a professional-grade bit set designed for use with impact drivers, offering exceptional durability and cam-out resistance for Pozidriv screwdriving applications.

At the heart of this set is Wera's Impaktor technology, which delivers above-average service life even under the extreme conditions generated by impact drivers. The diamond-particle coating on each bit tip creates a rough surface that bites firmly into the screw head, significantly reducing the risk of slipping and cam-out — a common frustration when driving screws at pace on site.

The included Wera 897/4IMP R Impaktor holder is purpose-built to absorb extreme impulse peaks through a double-torsion spring mechanism. It holds long and heavy screws securely in position, making it particularly practical for overhead work or any situation where precise, one-handed screw placement is needed.

The holder's magnetic retaining ring can be removed from the screwdriving zone when working with metal, giving the user full control over magnetic engagement. Compatible with standard 1/4" hexagon power screwdrivers, this set is well suited to carpenters, joiners, site workers, and contractors who rely on impact drivers for high-volume fastening work.
