BiTorsion system - for longer service life
A special tempering process reduces the hardness of the shaft of BiTorsion bits by approx. 20% compared to the drive end. The torsion zone cushions higher impacts. An integrated torsion spring in the BiTorsion holder absorbs smaller impacts.
From Wera Werkzeuge
1: Smaller impacts are absorbed by the holder
2: ...higher impacts are cushioned in the torsion zone of the bit
3: No premature wear caused by impacts
