This professional bit set features Wera's innovative BiTorsion technology, combining an elastic torsion zone that diverts kinetic energy during peak loads with a softer zone that prevents tip twisting, significantly extending service life compared to standard bits. Designed specifically for Pozidriv screws, these extra hard bits are particularly suited to semi-hard materials where conventional bits may struggle. The 1/4" hexagon drive conforms to DIN ISO 1173-D 6.3 standards, ensuring compatibility with standard bit holders across Wera's connecting series 1 system. The practical Bit-Box storage solution keeps your bits organised and protected on site, whilst the "Take it easy" Toolfinder system uses colour coding and size stamps for quick profile identification. Ideal for carpenters, electricians and maintenance professionals working with Pozidriv fixings in timber, plastics and composite materials, this 20-piece set provides excellent value for tradespeople who demand reliability from their fastening tools.
