Hey Hu, can you use 4 flute EMs on aluminum? I usually see the 2 flute guys being used and I notice that all of the aluminum EMs advertised are 2-3 flute, but if I could move faster that would be nice. Does a 4 flute give a finish on aluminum? Don't know why I never tried one.
I used a 3 flute EM once but it was a long 1/4 " one that chattered so bad I never tried it again. Prob. just did not have the feeds / speeds right. |
