Jimmy, the old burke is 3c collets, max shank size is 1/2" I am trying to find a collet closer for my south bend lathe, it will accept 5c collets and I could turn down the shanks of hss end mills to 1/2" with carbide cutters on the lathe I think.
No Jimmy, I don't have anything for ceramics and I have never used them.turning hss with carbide is a chore, it will knock the edge off pretty quick, better off using ceramic, do you have a holder for the ceramic disks? i think they are about 3/4" round x 3/16"-1/4" thick? if so i will send along a ceramic puck as well.
