• ### Cutting Speeds RPM Calculations

Spindle speed settings on the drill press are done in RPMs. To calculate the proper RPM for the tool we must use the following formula Cutting speed (CS) X 4 Diameter of cutter (D) This simplified version of the RPM formula is the most common formula used in machine shops. This RPM formula can be used for other machining operations as well.
