Frequently Asked Questions
Surface Feet per Minute (SFM) is the linear speed of the cutting tool relative to the workpiece. It depends on the material being cut.
Inches per Tooth (IPT) is the amount of material removed by each cutting edge per revolution. It affects surface finish and tool life.
RPM = (Cutting Speed (SFM) * 3.82) / Tool Diameter (inches). The constant 3.82 converts SFM to RPM.
