Why Flute Count Matters In The Loupe Machinist Blog

While adding a 5 th flute to a 4 flute tool theoretically gives you 25% more material removal per revolution with an appropriately increased feed rate, feeding the tool that much faster may overload the tool. The 25% increase in material removal is more likely closer to 1015%, given the tool is exactly the same in all other specifications.
