High-quality bits with a Torsion zone - where kinetic energy is diverted from peak loads. This greatly extends the product service life. Tough viscous, for universal use. ¼" hexagon, suitable for holders as per DIN ISO 1173-F 6.3.

TZ-Bits are tough bits with a torsion zone. Torsion bits absorb the damaging peak torque loads in the torsion zone. This prevents premature wear and enhances the service life of the bits.

Tough-absorbing Wera bits (Z) prevent any premature breakage of the drive tip.
