On drill bits the fastest cutting rate is at the circumference and its rate of travel is equal to the RPM (Revolutions Per Minute) of the bit times the circumference (pi Diameter). So the translation between SFM and the RPM speed of a drill bit is Rotation Speed (RPMs) = (3.82) SFM / Dia. SFM = (.26) RPM dia. Some considerations for

Ball nosed cutters slow nose speed. The biggest challenge with ball nosed end mills of various kinds is slow nose speed. As you get closer to the tip the diameter on the ball gets smaller and smaller finally going to zero. As a result the cutter must perform over a wide range of surface speeds and chip loads at different depths in the cut.
