Tom,

Yes, it is one of the few pieces of stock in my stash that I bought in person from a reputable local supply house. I tried a couple of different types of cutting oil but found that no cutting oil gave me the best finish. It seemed very gummy and would gouge rather than cut.

I'll use those dull end mills for side cutting only since just the bottom .015" or so is dull.

Nothing wrong with taking that .015 off with the bench grinder.  When it's close, put the endmill in the mill, and with a scrap of paper under each point use a stone on the high one to bring them all level with each other. I use these as "roughers"..

It's somewhat like sharpening drill bits - the big ones are easy, the small ones not so much.
