    摘要： A saw blade having improved metal cutting characteristics in which the tip of each tooth is formed to provide a primary rake face extending from the tip of the tooth for a distance of 0.007 to 0.020 inch and having a positive rake angle of 12.degree. to 25.degree., a secondary rake face extending from the primary rake face to the gullet of the tooth and having a positive rake angle less than 12.degree., a primary end relief surface extending from the tip of the tooth for a distance of 0.007 to 0.030 inch and forming a relief angle of 10.degree. to 25.degree., and a secondary end relief surface extending from the primary end relief surface to the gullet of the next successive tooth and forming a relief angle greater than the relief angle of the primary end relief surface. The blade can be made by applying a deforming force to the tips of the teeth of a precursor saw blade.

    摘要： A tool includes first and second elongated members, each member having a handle portion at one end and a jaw portion at an opposite end. Intermediate portions of the members are movably coupled to one another. Movement of the handle portions opens and closes the jaw portions. Each jaw portion includes a gripping surface configured to grip a workpiece. A pair of blade members are rigidly secured to the jaw portions, each blade member having a cutting edge.

    摘要： The present invention provides a method and apparatus for forming a plurality of parts, such as spade-type boring bits, from a continuous stock material. Thus, the various steps of the forming method of the present invention can be performed to predetermined portions of the continuous stock material prior to separating the continuous stock material into discrete parts, thereby enhancing the efficiency of the forming process. The present invention also provides an improved forge for forming portions of the continuous stock material into parts having a predetermined shape. The forge can be designed to provide a clearance region proximate the forward end of the ram to permit slight flexing of the forward end of the ram in a radially outward direction during forging operations. The forge can also include a lubrication system for lubricating its various components. In addition, the forge can incrementally rotate the ram after one or more parts have been forged. By repeating the incremental rotation of the ram, the forge will eventually rotate the ram a full 360°. An improved forging die is also provided which includes a back surface having a conical medial section and a pair of conical lateral sections that are recessed relative to the medial section such that forces will principally be applied to the medial section during forging operations.

    摘要： A cutting tool (200, 202) has a longitudinally extending shaft portion (208) with a chucking part (204) and a cutting head (206). A cutting edge (220) is formed on the cutting head (206). The cutting edge (220) includes at least one cutting portion. A rake surface (224) is formed adjacent to at least one of the cutting portions (220) with the rake face being at a rake angle in the range from about −10° to about 10°. A clearance face (226) is formed adjacent to the at least one cutting portion opposite the rake face (224). The clearance face (226) is at a clearance angle in the range from about 10° to about 50°. An edge radius between the rake face and the clearance face is at a radius of from about 0.0003 to about 0.0040 inch.
