This is a dumb question, but what are the relative advantages of
4-Flute vs. 2-Flute end mills, and on what applications should one type

2 flute can plunge cut, 4 flute cannot.


Not true. Center cutting 4 flute end mills are available. See above
comments on clearances for aluminum versus steel cutters. That, and chip
clearance, are the real issues.
