ABSTRACT:
A tool for cutting tubular members has a rotatable cutting assembly adapted for mounting on the end of a tool body. The cutting assembly includes a rotatable base member having two support elements which support two cutting heads on the base member. The support elements are each pivotally mounted on the base member such that rotation of the base member causes each support element to pivot around an independent axis. Each support element has one or more weights located on one side of the axis and a cutting head located on the other side of the axis. Centrifugal force developed during rotation of the base member cause the weights of each support element to swing radially outwardly while the cutting heads pivot radially inwardly into cutting contact with the tubular member and cutting same.
