Wera 30 Piece Bit-Check Bitorsion Screwdriver Bit and Holder Set

The Wera 30 Piece Bit-Check BiTorsion Screwdriver Bit and Holder Set is a professional-grade bit assortment designed for tradespeople who demand durability and fast bit changes during demanding screwdriving work. At the heart of this set is Wera's BiTorsion technology, which incorporates a torsion zone that absorbs and diverts kinetic energy away from peak load points. This significantly reduces stress on the bit tip, extending service life compared to standard screwdriver bits — making this set well suited to electricians, joiners, and contractors using power screwdrivers or drill drivers throughout the working day. The included 889/4/1 K Rapidaptor Universal Bit Holder accepts bits without the need to actuate the sleeve, and releases them with a single forward push — enabling one-handed bit changes that keep work moving. The holder accepts 1/4" hexagon shank bits to DIN ISO 1173-C 6.3 and E 6.3, compatible with power screwdrivers and power drill chucks. The 30-piece set covers the most commonly used profiles on site — Phillips, Pozidriv, and TORX® — with multiple quantities of the most frequently used sizes. All 29 bits are housed in a compact, lightweight multi-component Bit-Check case. The soft lower section grips bits securely while allowing easy removal, and Wera's colour-coded Take it Easy Tool Finder system makes identifying the correct bit profile and size quick at a glance.
