  • External refacing indicator for a tool joint
    Patent number: 6896300
    Abstract: Makeup plates on the abutting surfaces of a tool joint pin and a tool joint box are provided. The makeup plates are recessed in a short distance from the outer diameter of the tool joint elements, such that when the joint is made up, the makeup plate develops an easily visible gap between the tool elements. In this way, a quick determination may be made, without measurement, as to whether the joint can be refaced, or require re-machining.
