Getting your feeds and speeds right is one of the best things you can do for cut quality and tool life — and the math is simpler than you might think.

Our latest guide breaks it down step by step: RPM, chipload, and flute count, with a real example cutting aluminum with the Onsrud 63-620. We've also included a troubleshooting section to help you dial things in when the cut isn't looking quite right.
