do tego kwestia mikrogeometrii samej płytkiDepth of cut and cutting forces
The relationship between nose radius and depth of cut affects vibration tendencies. The radial forces that push the insert away from the cutting surface become more axial as the depth of cut increases.
It is preferable to have more axial forces than radial. High radial forces can have a negative effect on the cutting action which can lead to vibration and bad surface finish.
As a general rule of thumb, choose a nose radius that is equal or smaller than the depth of cut.

Pry tak małej ap promienia praktycznie nie powinno być wcale, ale to z kolei osłabia wierzchołek ostrza.
