Selecting A Parting Tool

That's just beautiful Ed! I'm not sure where you were at for feed rate, though I believe you could use up to twice that feed without any issues. You could also use more speed if desired, and that would put more heat into the chips. Anytime you can get the chips running straw to blue color, you're carrying most of the heat out of the cut with the chips and saving the workpiece and stock from getting hot.

I really don't know all that much, just know how to put on a good show. I'm in sales, remember?
