BiTorsion Tips

In mechanical screwdriving, bits and bit holders are exposed to extremely high torque peaks, which frequently leads to significant bit wear or even screw failure. Minimizing these torque peaks makes screwdriving more productive and safer. Wera's BiTorsion system prevents premature wear, extending tool life and significantly increasing mechanical screwdriving productivity.

The effect of the BiTorsion system

The BiTorsion system's effect is based on the combination of two spring elements capable of absorbing shocks. Both the tips and the tip holder have a damping torsion zone that, in the case of torque peaks, transfers the kinetic energy away from the tip end.

BiTorsion phase 1

The torsion zone integrated into the BiTorsion bit holder dampens minor torque peaks (phase 1). A support mechanism effectively protects the torsion zone from overload.

BiTorsion phase 2

The larger peaks are minimized through the torsional effect of the tip stem (phase 2).

Increased tool life

By using the BiTorsion bit holder, the lifespan of conventional bits increases, and - on the other hand - a BiTorsion bit also works with a regular bit holder.

Item description

BiTorsion bits for hexagonal screws with an elastic torsion zone that transfers kinetic energy during peak loads. A softer BiTorsion zone prevents the shank end from bending under very high loads, significantly increasing tool life. Extra-hard version. 1/4" hexagon, suitable for bit holders according to DIN ISO 1173-D 6.3.
