Wiha Torsion bit.

Patented torsion zone for longer service life.

The main cause ofwearwithsoft
fasteningapplicationssuch as in
wood for example isthewearofthe
profile edges because the bit rattles
through. A hard bit needs to be used
here: Wiha HOT.

With hard fastening jobs such as
hitting metal surfaces the main
reason for wear is breakage of the
bits. These usually occur with torque
peaks near to the end of the fastening
process.A tough-but-flexible bit is
the answer: Wiha ZOT.

The special assortment of Wiha
torsion bits with torsion zones offers
optimal products for both soft and
hard fastening tasks.

concerning elasticity are used
to optimise performance and
resistance to wear and tear
(blue line)

• For trade and DIY

The red line indicates the steep
increase in torque with hard
applications, e.g. in metal.

The blue line shows a steady
torque increase in soft applications,
e.g. in wood working.
