2.Measure the diameter of your cutting tool in inches.

3.Use the following formula to determine the needed RPM for your operation:

Note: You will only be able to get an approxi- mate RPM value with the gearbox range and reduction levers.

4.Move the mill gearbox levers to the nearest milling speed RPM.

NOTICE

Failure to follow RPM and Feed Rate Guidelines will shorten cutter life and give poor workpiece results and may threaten operator safety from ejected parts or broken tools.
