Could anybody also give me some advice on the differences between the 2 and 4 flute cutters. I bought a center cutting end mill kit which has both types, two flute and four flute.
Currently, I'm under the impression that a two flute end mill will allow the user to IPM around quicker but leave a poor finish behind, which is where the four flute mills come into play for the finish pass right? Now assuming that this is indeed the case, Could a guy instead just start with the four flute mill and just go a little slower in order to avoid a tool change? What strategy will minimize the number of tool changes for a guy who doesn't have an ATC mill but still leave a nice finish behind on aluminum?
