摘要： A reverse spot-facing tool for cutting a reverse spot-face in a workpiece using a reverse spot-facing cutter configured to engage a pilot shaft having a first end and a second end is disclosed. The workpiece comprises a through hole having a central axis. The reverse spot-facing tool comprises a stop configured to be located between the first end and the second end of the pilot shaft; a biasing assembly that generates a first thrust force and an equal and opposite second thrust force when the reverse spot-facing cutter is cutting the reverse spot face; and a thrust bearing configured to be positioned between the biasing assembly and the stop. When the reverse spot-facing cutter is cutting the reverse spot-face, the thrust bearing transmits the second thrust force from the biasing assembly to the stop, and the biasing assembly transmits the first thrust force to the workpiece.
