Tough-absorbing bits for universal use. BiTorsion bits with an elastic torsion zone - where kinetic energy is diverted from peak loads - and softer BiTorsion zone to prevent the bit tip from twisting under high strain. This greatly extends the product service life. Offer the best possible service life with the appropriate holder.

The multi-component Bit-Check is convincing on account of its low weight and the maximum possible degree of compactness. In this respect, the soft material in the lower section of the Bit-Check ensures that the bits are securely held whilst being simple to remove at the same time.
