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.

Tools and methods for refacing tubular ends forming a threaded connection

A portable and field-adjustable milling machine comprises: a base; a milling assembly coupled to the base and that includes a milling tool rotatable by a driver; a roller bed coupled to the base and configured to support a tubular member thereon; and a vice assembly that is coupled to the base. Each vice member of the vice assembly is configured to be moved towards the other of the pair and includes camming surfaces configured to lift the tubular member off of the roller bed in response to the vice members being moved toward one another. The vice member may have a v-shaped notch defined by a pair of angled surfaces. The vice assembly lifts the tubular member and retains it in the notch at a position that is a predetermined distance away from the roller bed.
