Apr 09, 2019 The 2 flute have a larger gullet so chip clearance. For smaller mills (below 1 2 inch) a 2 flute is a better roughing mill. For finish work or in hard materials, you need cutting edges so use a 4 flute. If you're going to be working in aluminum, you'll want to get some high Helix end mills. The same principle applies between 2 and 4.
