Wera Bit-Safe comprehensive torsion bits and Rapidaptor holder set is designed for users on the move needing a broad selection of drive profiles with multiples of the same bit. Utilising a combination of special materials, hardening and precision manufacture, BiTorsion bits are designed to prevent premature wear and dramatically extend service life. Torsion zone absorbs peak stress loads that normally destroy bits. Diamond-Coated (BDC) bits ensure safe working, especially driving screws into delicate materials or high-quality surfaces, preventing slip. Additionally, where screws are driven into resistant materials such as hard woods, concrete screws and ABS plastics diamond-coated bits ‘bite’ into the fastener ensuring a secure fit and reducing cam-out effect. Extra-Tough (BTZ) bits are suited to metal joiting, threaded fasteners and general use. Gold Extra Hard (BTH) bits are designed for driving screws into normal construction timbers and materials. The holder, with quick-release chuck, offers press-in auto-lock and rapid one-handed bit changes for insert and power bits. The holder spin sleeve allows steady screwdriving. Wera Bit-Safes feature a compact design to safely store bits and bit holders in a handy structured fabric case where the tools are easily accessed.
