Frequently Asked Questions

RPM formula
RPM = (SFM × 12) / (π × D), where SFM = surface feet per minute, D = tool diameter in inches. Metric: RPM = (Vc × 1000) / (π × D_mm).
Why SFM matters
Every material has optimal cutting speed. Too fast burns tools. Too slow causes work hardening. Target SFM = best balance.
