The effectiveness of the BiTorsion system comes from a combination of two shock-absorbing spring elements. Both, bits as well as holders have a cushioning torsion zone that diverts the kinetic energy away from the drive tip during peak loads.
Smaller impacts are absorbed by the holder
The torsion spring integrated into the unique BiTorsion holder absorbs lower levels of peak loads (Phase 1). Any overloading of this spring is effectively prevented by means of a supporting mechanism.
...higher impacts are cushioned
in the torsion zone of the bit
Higher peak loads are minimised through the torsion effect of the bit shaft (Phase 2).
