  • Patent number: 4071141
    Abstract: A plurality of individual, pre-formed cutting tips attached to one another in an adjoining series to form an elongate stick of tips for sequential attachment to the teeth or cutting portions of cutting tools. Each tip in the stick has a commonly oriented contact surface for attachment to the cutting tool, and a separate pre-formed cutting edge that forms the cutting edge of the tool once the tip has been attached. Attachment of a tip to a cutting tool is accomplished by positioning the contact surface of the lead tip in a stick proximate the tool, and severing the connection between the tip and the remainder of the stick. The tips forming the stick are preferably attached to one another by a meltable adhesive spread over their respective contact surfaces, such adhesive having a melting point lower than that of the tips. The respective tips in the stick are operatively connected to separate teeth or tools by the same adhesive.
