Anything that would be called a sanding bit or grinding bit is too coarse.  The type marflow references is probably fine though—a rubber material impregnated with a fine abrasive.  Another good approach is using a round head brass screw slathered with a fine compound like J-B bore paste.  It’s slow but purposely so to ensure no burr remains.
