  • Cutting tip reseater
    Patent number: 4001982
    Abstract: Apparatus for reseating the two or more sealing surfaces of a cutting tool tip is disclosed. The sealing surfaces of such a cutting tool tip are conformed to a common conical shape. The apparatus of the present invention includes a support member which has a conical interior cavity conformed to the common conical shape of the sealing surfaces. A slit is provided in the support member which communicates with the cavity so that a sheet of emery paper can be inserted through the slit to circumscribe and conform to the interior surface of the cavity. As a result, a damaged cutting tool tip can be inserted in the cavity with the sealing surfaces thereof flush with the emery paper and rotated to reseat the seaing surfaces in the common conical shape.
