Feed & Speed Charts for Solid Carbide Spirals


Feed Rate = RPM x Number of Flutes x Chip Load
RPM = Feed Rate / (Number of Flutes x Chip Load)
Chip Load = Feed Rate (Inches Per Minute) / (RPM x Number of Flutes)

Feed Rate Chart Using Solid Carbide Routers in Wood

*Based on 1/2" Diameter Tool, Cutting 3/4" Stock at 18,000 RPM
All Figures Are Shown As IPM (Inches Per Minute)


Note: For smaller diameters than reference in the charts - Reduce feed rate
For larger diameters - Increase feed rate
