How to polish drilled holes?

 A properly drilled hole has a smooth semi-matte finish that can be brought to a high polish.

  • A wood or metal rod approximately 1/8 inch smaller in diameter than the drilled hole is split to a depth equal to the depth of the hole plus 1/2 inch and mounted in a drill press.
  • If the inner surface of the hole is rough, steel wool or strips of emery cloth or sandpaper are wound around rod and gripped in the slot.  
  • When the inner surface is smooth, a good grade of flannel is wound around the rod and the compounds for buffing are applied.
