A spot facing tool is mounted on a work table with an arbor located beneath the work table and movable upwardly through an opening in the work table. A cutter holder is mounted on the surface of the work table with a cutter receptacle positioned in alignment with the arbor. A cutter is releasably retained in the receptacle. The arbor is movable upwardly through the opening of a work piece and into the cutter, and connected to the cutter. The cutter and arbor are moved downwardly until the cutter engages the work piece and rotation of the cutter and arbor causes spot facing of the work piece about its opening.
