Recommended cutting data

Starting values for stable conditions with good coolant supply. Adjust for your machine, set-up and workholding. For diameters between the listed values, interpolate between the neighbouring rows.
Spindle speed n = Vc × 1000 / (π × D)  ·  Feed rate vf = n × fz × z (drills: vf = n × fn).
