  • End mills- 2 flute or 4 flute Practical Machinist

    Apr 09 2019 · The 2 flute have a larger gullet so more 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 more 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
