As for end mills? Get cheap two flute ones since they're going to be broken by the students most likely  |
I think the gears in the head/ belt will die before the end mills do if you crash. Those Grizzly mills have problems with that.
We use two flute end mills for aluminum because they can remove more metal due to the large flutes (according to my teacher). However, for such a small/ low HP mill four flute may be better for removal of metal. 4 flute is not that much more expensive than 2 flute.
