I just got a 1 inch R8 end mill holder because I have a drawer full of end mills with that shank size that I used to usein my lathe before I got a mill. They all fit the new holder but one. As (bad) luck would have it, the end mill that doesn't fit is one of my favorites. By the seat of my pants I don't think it's even a thou oversize. What's the tolerance on a one inch EM shank?
