Wera 10 Piece Bit-Check BiTorsion Screwdriver Bit and Holder Set

The Wera 10 Piece Bit-Check BiTorsion Screwdriver Bit and Holder Set is a compact, professional-grade screwdriver bit set designed for tradespeople who need a reliable, organised selection of bits close to hand on site. At the heart of this set is Wera's BiTorsion technology, which incorporates a dedicated torsion zone into each bit. This zone absorbs and redirects the kinetic energy generated during peak loads, significantly extending service life compared to standard screwdriver bits. The result is a more durable bit that holds up under the demands of regular professional use. The included 897/4 R Rapidaptor holder makes bit changes fast and simple. Bits are attached without the need to actuate the sleeve and removed by a single forward push — allowing one-handed operation that keeps workflow efficient on the job. The holder accepts 1/4" hexagon shank bits to DIN ISO 1173-C 6.3 and E 6.3, making it compatible with power screwdrivers and electric drill chucks alike. The Bit-Check casing keeps the full set organised and portable, standing upright on the workbench or fitting easily into a shirt pocket. Colour coding by profile and size makes it straightforward to identify the right bit at a glance, reducing time spent searching. This set is well suited to electricians, joiners, and general contractors working across a range of fastener types, covering Phillips, Pozidriv, and slotted profiles in multiple sizes.
