Why Flute Count Matters

Sep 26, 2017· Material Considerations. Traditionally, end mills came in either a 2 flute or 4 flute option. The widely accepted rule of thumb was to use 2 flutes for machining aluminum and non-ferrous materials, and 4 flutes for machining steel and harder alloys. As aluminum and non-ferrous alloys are typically much softer than steels, a tool's strength is less of a concern, a tool can be fed faster, and
