Abstract: A trepanning tool that is characterized by the provision of a cylindrical cutting head projecting coextensively from a shank that has an axis of rotation. Consumable cutting elements are releasably attached to the cutting head in axially projecting relationship therewith and these elements are also releasably secured against movement radially, circumferentially and axially of the cutting head. The tool also has a relieved wall section in the cutting head extending axially and circumferentially so as to provide a means of chip egress during the cutting operation.

Abstract: A CUROFF OR GROOVING TOOL THAT INCLUDES A HOLDER AND A REPLACEABLE CUTTING INSERT WITH THE HOLDER INCLUDING A MAIN BODY PORTION, A SUPPORT BLADE, AND A CLAMPING ARM AND WITH THE INSERT BEING AN ELONGATE, RELATIVELY PENCILLIKE COMPONENT ADAPTED TO BE SEATED ON THE BLADE OF THE HOLDER AND CLAMPED IN PLACE THEREON BY THE CLAMPING ARM WITH A BACKUP ELEMENT SERVING TO DETERMING THE EXTENT OF LONGITUDINAL PROJECTION OF THE CUTTING INSERT ON THE SUPPORT BLADE. THE INSERT AND HOLDER ARE CHARACTERIZED BY COMPLEMENTARILY ENGAGED V-SHAPED SURFACES OF THE TYPE SET FORTH IN NOVKOV U.S. PAT. 2,964,833. THE SHANK PORTION OF THE INSERT GENERALLY HAS A LESSER HEIGHT THAN THE SHANK PORTION OF THE INSERT SHOWN IN NOVKOV PAT. 2,964,833 WHILE THE CUTTING TIP PORTION THEREOF HAS A PROPORTIONATELY GREATER HEIGHT THAN THAT OF THE INSERT SHOWN IN NOVKOV U.S. PAT. 2,964,833. USE OF THE BACKUP COMPONENT REARWARDLY OF THE INSERT PERMITS USE OF A SERIES OF SUCH MEMBERS SO AS TO INSURE CORRECT POSITIONING OF INSERTS HAVING SHANK PORTIONS OF DIFFERENT LENGTH.

Abstract: A cut-off or grooving tool that includes a holder and a replaceable cutting insert with the holder including a main body portion, a support blade, and a clamping arm and with the insert being an elongate, relatively pencil-like component adapted to be seated on the blade of the holder and clamped in place thereon by the clamping arm with a backup element serving to determine the extent of longitudinal projection of the cutting insert on the support blade. The insert and holder are characterized by complementarily engaged V-shaped surfaces of the type set forth in Novkov U.S. Pat. No. 2,964,833. The shank portion of the insert generally has a lesser height than the shank portion of the insert shown in Novkov U.S. Pat. No. 2,964,833 while the cutting tip portion thereof has a proportionately greater heighth than that of the insert shown in Novkov U.S. Pat. No. 2,964,833. Use of the backup component rearwardly of the insert permits use of a series of such members so as to insure correct positioning of inserts having shank portions of different length.
