Wera 855/4 11 Piece Impaktor Pozi Screwdriver Bit Set

The Wera 855/4 11 Piece Impaktor Pozi Screwdriver Bit Set is a professional-grade bit set designed for use with impact drivers, combining durable Impaktor bits with a purpose-built magnetic holder.

At the heart of this set is Wera's Impaktor technology, which extends bit service life significantly even under the extreme stresses of impact driving. The rough diamond-particle coating on each bit tip creates enhanced friction between the bit and screw head, biting into the Pozidriv recess to prevent cam-out and reduce operator effort. The bits feature a 1/4" hexagon shank compatible with holders to DIN ISO 1173-F 6.3.

The included Wera 897/4IMP R Impaktor Ring Magnet Holder is engineered to absorb extreme impulse peaks through a double-torsion spring mechanism. This torsion effect protects both bit and driver during heavy-use applications. The magnetic retaining ring holds long and heavy screws securely in position, making it particularly useful for overhead work or awkward access. Where magnetism is undesirable — such as when working with certain metals — the magnet can be repositioned away from the screwdriving zone.

This set is well suited to carpenters, joiners, and general contractors who rely on impact drivers for repetitive fastening tasks. The ten PZ2 bits cover the most commonly used Pozidriv size across timber fixing and construction work.
