I'm just making a fly cutter for the mill from a chunk of 35mm SS that I had, I was going to use drill rod for the cutter, I have some 3/16" and some 1/4" but then I found a piece of 8mm HSS, does anyone think that 8mm is too big for the cutter? ,I am going to drill in at 45° and does anyone have any thoughts for the best shape for the cutter?
