Abstract: A reverse chamfering and countersink stop tool allows the required diameter of a countersink in a workpiece to be maintained in areas that have limited accessibility for the user assembling a fastener to the workpiece. The tool controls the dimension required for proper installation of fasteners under such conditions. The tool can also be used for other applications that require control of the diameter of a chamfer, and allows the diameter of the chamfer/countersink to be set outside the point of use for maintaining proper tolerances. The tool utilizes a modified reverse countersink cutter that is captured inside an externally threaded adjustable stop housing. The captured cutter is movable both axially and rotationally, and is driven by a drill equipped with a pilot. The stop position of the cutter is controlled by a series of nuts that are located and threaded on the exterior of the housing.

Abstract: Adjacent one end thereof the shank of a back spotfacing tool has therein a transverse slot, and a cutter mounting pin which extends between opposite sides of the slot parallel to the shank axis. A cutter has in one end thereof a U-shaped slot which is inserted removably over the pin to support the cutter for limited pivotal movement about the pin into and out of an operative position in which a flat, external, limit surface formed on the side of the cutter remote from the open end of its U-shaped slot engages the bottom of the slot in the shank to support the cutter for a cutting operation, and to prevent removal of the cutter from the pin. The cutter may be swung manually to an inoperative position in which the open end of its slot is positioned to permit removal of the cutter from the pin, or the replacement thereof over the pin.

Abstract: A bearing may consist of one or more components where relative motion can take place between the bearing surface and a mating surface and where the mating surface may be a component of the bearing. Many bearings are circular and may be installed and secured in a housing by swaging an annular outer lip into an annular chamfer of the housing. A tool is provided for facilitating the removal of the bearing. The tool employs one or more cutter teeth which engage the swaged lip of the bearing. Axial force applied to the cutter while it is rotated effectively cuts away the annular lip thereby allowing the bearing to be pressed out of the housing. The cutter may be used in conjunction with other tool components which include (a) a bolt which extends through the center of the circular bearing, (b) centering rings which correctly orient the bolt relative to the annular lip of the bearing, (c) a nut and (d) Belleville washers which are disposed between the nut and the cutter.

Abstract: A cutting tool for finishing a back surface of a workpiece having a hole is proposed. A blade having an equilateral triangular shape is attached to a shaft of the cutting tool. One of cutting edges formed along the sides of the blade projects transversely of the shaft. The tip of the projecting cutting edge comes to contact the workpiece's back surface. When the workpiece is rotated and the shaft is moved in the diametrical direction relative to the hole, the cutting edge tip grinds the back surface. At this time, if the shaft moves in the longitudinal direction of the workpiece, the blade creates a notch in communication with the hole on the workpiece's back surface, resulting in a stepped borehole.
