Robust Bit-Check by Wera. Bit-Checks provide a quick overview of the tools available. Bits not needed are simply reinserted into the set and do not get lost. Simple transportation e.g. in the shirt pocket. Tough viscous bits for universal use. BiTorsion bits with Torsion zone – where kinetic energy is diverted from peak loads. This greatly extends the product service life. This provides the best possible durability together with the matching holder. Comes with Rapidaptor technology, which allows bits to be attached without any need to actuate the sleeve. The removal of the bit is simple, just by pushing the sleeve forward – for rapid bit change with just one hand. For the take-up of bits with ¼” hexagon head drive as per DIN ISO 1173-C 6.3 and E 6.3. Can be inserted in the power screwdriver or for use in the chuck of the electric drill.
- At the workplace: The Bit-Checks can be positioned upright at the workplace so the tool is always quickly to hand.
- BiTorsion Bits: With BiTorsion zone to cushion peak loads.
- BiTorsion Rapidaptor: BiTorsion holders from Wera have a torsion spring design that absorbs smaller peak loads during screwdriving. The combined use with BiTorsion bits with their torsion zone distinctly extends the service life of the tool. Conveniently, BiTorsion holders from Wera can also be used with conventional bits.
- Above-average service life: Even the service life of conventional bits is enhanced with the use of the BiTorsion holder and the BiTorsion bit also functions in a normal holder.
- BiTorsion phase 1: The torsion spring integrated into the unique BiTorsion holder absorbs lower levels of peak loads (Phase 1). Any overloading of this spring is effectively prevented by means of a supporting mechanism.
- BiTorsion phase 2: Higher peak loads are minimised through the torsion effect of the bit shaft (Phase 2).
- BiTorsion and conventional tools: The BiTorsion holder and the BiTorsion bit can, of course, be used independently of one another.
- Rapid-in and self-lock: The bit can be pushed into the adaptor without moving the sleeve. The lock is activated automatically as soon as the bit is applied to the screw. Bits are held securely and wobble-free
