The following illustration compares a HPC cutter with irregular
pitch to a HPC2 end mill additionally characterised by a varia-
ble helix angle and core diameter. It shows the 'linear' length of
the cutting edge or length of the helical flutes of the tools. This
points out the difference of the variable helix angle of a HPC2
W4420 end mill when compared with a solid carbide milling
cutter commonly used on the market, one that has a constant
helix angle over the entire length of the groove.

Resulting forces
Compared to competitor tools, the HPC2 tool exhibits notably
lower forces generated by the tool (see chart). Improvements
in tool life of up to 45% are achieved when the cutting forces
are equal.
