Cutting Speeds

This calculator gives guideline cutting speeds for a specified diameter. Slide the diameter back and forth and the table will update for the various materials. You can also enter a custom surface speed in metres per minute and see the cutting speed in RPM for the specified diameter.

The table at the bottom shows the values of surface speed (in metres per minute) that are used for the calculation of the values (in RPM) in the top table.
