* For the cuts that are not strictly tip-cutting, but will use both the tips and sides of the SBN insert, pick an effective cutting diameter in between the ECD in the chart and the actual diameter of the insert. For example: If the ECD comes out to .210" with a .750" diameter insert, use .480" as your ECD when calculating RPM.
These feed rate multipliers are for applications involving tip-cutting only. For applications including side-cutting or slight/draft angles, lower the multiplier by 20-50%.
Use multiple above to calculate adjusted feed rate.
