For appropriate speeds, please consult the following tables:

Aluminium/Brass 2500 1880 1370 1370 900 900

A blank space means that theres no suitable speed available for cutting that size hole. Italics means that the speed listed is close, but not actually in the recommended range.

Notes from an experienced machinist:

  • base formula for mild steel is 9000/diameter (in mm)
  • Prefer a slower speed than faster
  • This is for general high speed (HSS) drill bits and end mills.
  • Four times faster if using carbide heads, you lucky bastard.
