Wiha Standard bit, hex, style C 8.
Optimal heat treatment
Wiha Professional Bits are fundamentally
through hardened
Heat treatment is carried out in hardening
systems with computer-controlled
monitoring of hardening
parameters (time, temperature, atmosphere).
This enables constant
hardening results. Wiha Professional
Bits gain their functional fine
finishing with the final annealing
process, a second heat treatment
following hardening that gives bits
a specific characteristic. According
to profile and application area, a
differentiation is made between
extra hard wear-resistant, tough
and extra tough.
