Tools that work well for parting are .060″ to .100″ (1.524 to 2.54 mm) wide with a 20 to 30 degree front rake and no top rake. A small 3/64″ radius is ground into the top of the tool. Starting on the cutting edge, some side clearance is helpful. Three to five degrees is all that is usually needed.

The proper tool, feed and speed allow the chip to exit the cut with little resistance and heat buildup. Parting yields a good surface finish and is a useful variation for facing certain urethane parts.
