System BiTorsion

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.

Two-stage cushioning:

Smaller impacts are absorbed by the holder... 

...higher impacts are cushioned

in the torsion zone of the bit

No premature wear caused by impacts
