Copy Mills M370 Series Additional Application Advice W0.J0804. Widia 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. Ap1 max 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. i Recommended when long overhang is necessary due to lower radial forces. Maximum L/D ratio of 10 x D.
