Abstract
A refacing tool includes a feed assembly that holds a first set of cutters positioned for refacing the inner shoulder of a pin or box end of a tubular and a second set of cutters positioned for refacing the outer shoulder of the pin or box end. The axial spacing between the first set of cutters and the second set of cutters is fixed and determined by the geometry of the feed assembly. The refacing tool can simultaneously reface the inner shoulder and the outer shoulder, as well as chamfers.
