ABSTRACT:
A cutting element and chamfering tool for pipe preparation is disclosed. The cutting element is formed from a ring having a split defining ends of the ring. One of the ends has a cutting edge. The one end is offset from the other to present the cutting edge to the pipe end. The ring has an inwardly facing angularly oriented surface that receives and centers the pipe end. The chamfer is cut when the ring and pipe end are rotated relatively to one another. The tool has a housing that holds the cutting element. The ends of the ring are offset when the ring engages a helical seat within the housing and/or when a radial set screw engaging the one end is tightened.
