The secret of
long blade life is here!
Impulse Hardening tempers only the surface leaving the core of the tooth flexible
|What is Impulse Hardening?|
hardening is the modern method of creating a saw
blade with a long working life.
The cutting edge is heated for 0.003~0.005 seconds by applying
a electrical current at 27.12MHz.
This creates a shock wave on the surface of the each tooh
that hardens it to Hv900~1200.
For comparison , sharpening files are only hardened to Hv800~850.
do saws from
other manufacturers fail?
manufacturers use a process that applies hardening
several times or two more than one tooth.
This causes uneven hardening and cracks will occur which
can cause the tooth to easily break.
