Hard to find them, and until the other day I put 3 flute endmills out of my mind. Way back when, my instructor always pimped them up to us students. My 3/4" 2-flute is approaching a nubbin and I need to replace it before it's gone. Looking through a catalog it all came back to me when I saw one -- a 3 flute single end from a local supplier, for $20.
I sharpen them by hand on a bench grinder; 4 flutes are a tad fussy, 2 flutes are a piece of cake. I'm hoping a 3 flute won't be too tough to do when the time comes.
Slotting and finishing. What say you guys? Boo, hiss, or whistles and applause for the things?
