Applying High-Feed Tools
The high-feed concept bases its strategy on small depth of cut
and higher fz values, which results in a higher MRR and productivity
with low radial forces.

Small Ap1 values and higher feed
rates generate lower cutting forces
versus traditional milling strategies.
For CAM programming, the tools
can be programmed as a toroidal
tool type by using the Rt value as
the insert radius.
Recommended when long
overhang is nece ssary due to
lower radial forces. Maximum
L/D ratio of 10 x D.
