I have an R-8 milling arbor that had a large unruly head that I don't want to use but I have one I want to use but has 800 thou hole the arbor is 1 inch. Using ccmt cheap carbide and slow feed and 500 rpm or so. I know that is slow but there not much to turn .anyway the chips are blue coils and stringy blue and hot as hell it sounds like a rock crusher turning it. Should I make one using 1 inch bar stock with a pin pressed in it? Or change feeds an speeds?
