    摘要： A finish reamer adapted to finish ream bronze-based valve guides and valve inserts is disclosed. The reamer includes a body section having a plurality of spiral flutes formed therein. The flutes define a plurality of cutting blades. Each cutting blade has an axially extending radial relief formed therein, and a land with a margin having a non-uniform width that is smaller near its leading end and larger near its trailing end.

    摘要： The present invention discloses a reamer (20) and a method for reaming, for enlarging a pre-existing hole in a workpiece by rotational and axial cutting. The reamer (20) includes a body (24) extending from a shank (22). The body (24) has a first flute (30) providing a first flute cutting edge (32) at a distal end (34) of the body (24) for imparting a first cutting operation to the workpiece. The body (24) has a helical flute (42) providing a helical flute cutting edge (46) in the body distal end (34), radially spaced apart from the first flute cutting edge (32) for imparting a helical cutting operation to the workpiece. The first flute and helical flute cutting edges (32, 46) concurrently and collectively perform the first and helical cutting operations to a sculpture surface of the workpiece, thereby improving tolerances of the cutting operations, varying loads imparted to the workpiece and the reamer (20), and reducing heat generated therebetween.

    摘要： A method and component for repairing broken conduit ends extending from concrete foundations is disclosed. The method and component for repairing broken conduit ends of this invention eliminates the need to break up the concrete foundation around the broken conduit end. The specialized repair components include a reaming bit for milling out and turning down the inside wall of the broken conduit end and repair coupling for joining a new section of conduit to the broken conduit end. The reaming bit is designed to be used with any conventional handheld power drill. The reaming bit mills out the inside of the broken conduit end so that the repair coupling can be inserted into the broken conduit end. With the coupling fitted into the broken conduit end, a new section of conduit can be connected completing the repair. Because the coupling is inserted into the broken end of the conduit instead of over it, the concrete foundation around the conduit does not have to be disturbed providing a structurally more secure repair.

    摘要： When inserting a finishing tool 41 into a bearing hole 13A3, firstly, by inserting an insertion guide portion 41c formed on the leading end side of the finishing tool 41 into the bearing hole 13A3, the finishing tool 41 is inserted into the bearing hole 13A3 in such a manner that the angle and parallelism of the axis of a pressure contact working portion 41b, which is situated on the rear side of the finishing tool 41 and continues with the insertion guide portion 41c, can be gradually aligned with the axis of the bearing hole through a floating holder mechanism 42. In a state where the axis of the pressure contact working portion 41b is automatically aligned with the axis of the bearing hole with high precision, the working of the bearing hole using the pressure contact working portion 41b is started. After then, due to the pressure-contact plastic deformation of the bearing hole by the pressure contact working portion 41b, the inner peripheral surface of the bearing hole of the bearing member is finish worked with high precision.
