Back to the original point of my post, I should have actually titled it, What should the proper cutting tool form be if... In this case, I've not yet cut the taper, and since I don't have a tool post grinder to do it, I'll be using HSS tool bits. What shape would be best suited for cutting an internal taper in 1018 crs.
For this last phase I'll be doing a 2º taper to fit the ECO 25 collets I have. Its a fairly short run, just under 2" deep. My compound will barely manage a full pass with that depth without having to reset.
