Basic Cutting Flute Designators
NOTE: When ordering tool, be sure and list basic cutting flute designators first and over cut designators become the second letter.
Milling Cut (RM)This style of fluting facilitates easy chip flow and effective stock removal with minimal loading. This cut achieves smooth, polished surfaces on softer metals, and is designed for reinforced plastics and nonferrous metals. Not recommended for use with flex shank burs.
Standard CutA general purpose cut, maintains aggressive stock removal, but allows for some blending and finish work.
Foundry Cut (O)Designed for general hogging usage on ferrous metals.
Coarse Cut (C)Rapid and aggressive stock removal from most metals. Used when finish is not important. Softer metals.
Stainless Cut (T)Special fluting for stainless steel and other exotic metals.
Fine Cut (F)Minimal stock removal. Used to achieve a blended and smooth finish.
