A perfect cut will look like a music CD. Lathes will start to cut to a mirror finish when the bits are starting to get dull. Then its not cutting as much as its pushing the metal around.

For years the standard cutting lube has been a plain old Sharpie marker. It lubricates just right and help minimize the amounts of copper you cut off..
