    Keep a low cut width (or cut depth if you’re talking the floor of a pocket or surfacing with a Face Mill) and do a separate finish pass. The depth of cut has to be larger than the chip load, or you can get rubbing. Usually something like 2-3x chip load will be right for the finish pass. I do a lot of finish passes in the 0.015″ neighborhood.
