| I cut 6061 that deep. It really is painful. When i can, I've had better luck using a c-cutting end mil like a drill. We have a 1"mill 8"L - it isn't pretty and we need to polish after cutting, but it works and if you control your rapid Z moves, its much faster (and ALOT less noisy) then side cutting. You may break mills only 1/2" - never tried them that small. Good Luck, I'd like to hear if you find a better solution. |
