The BiTorsion bit system

Distinct extension of service life

Peak forces that occur in power tool applications often result in premature wear of bits or
damage to the screw head. This usually occurs during initial power-up and the when the
screw comes to a standstill.
Screwdriving could become more productive and safer if these peak loads could be

minimised. The Wera BiTorsion system prevents premature wear. The service life of the tool
is extended and the productivity of power tool applications signifi cantly increased.

• The BiTorsion tools can also be used individually.
• The BiTorsion holder and the BiTorsion bit can, of course, be used independently
of one another.
• Even the service life of conventional bits is enhanced with the use of the BiTorsion
holder and the BiTorsion bit also functions in a normal holder.
The optimally coordinated features of
the torsion zones on the bit and holder
permit a phased yield when under
strain. The two-phase system prevents
premature wear. Moreover, a long tool
service life is also ensured by the
hardness of the bits that matches the
respective application.
