    摘要： A high-speed tap (1) for cutting a female screw by cutting edges (E) of a screw portion (2) fed in synchronous with the rotation of a machine tool. The high-speed tap is characterized in that chamfers (CF) are provided at a leading portion (2a) of the screw portion (2). The chamfers (CF) start at a cutting edge (E) and are located along ridges (R) between a crest surface (2e) and flanks, or a following flank (2c) and a leading flank (2d). This structure enables the shape of the edges of the tap leading portion to be stably maintained and high-speed, smooth female screw cutting with high accuracy, and provides a tap with long life.

    摘要： A precision cemented carbide threading tap is designed for use in precision tool holders in synchronous high speed tapping. The precision tap includes a fully cylindrical shank without the aid of squares, flats or other notches. The precision tap further includes a threaded body portion and a threaded cutting chamfer portion. The threaded body portion and the threaded cutting chamfer portion of the precision tap are concentric to the cylindrical shank of the tap within a runout of 10 microns. The precision cemented carbide threading tap improves the accuracy, life and speed by which internal screw threads are produced.

    摘要： A coated carbide tap comprises a substrate consisting of tungsten carbide cemented with 12 to 16% by weight cobalt with additions of small amounts of transition metal carbides added to restrain grain growth, and may also contain low levels of impurities that might be picked up during processing. The substrate is coated with a layer of metal nitrides, carbides, carbonitrides, borides and/or oxides, the metal being chosen from one or more of the following: aluminum, silicon and the transition metals from Groups IVa, Va, and VIa of the Periodic Chart. The coating may comprise a monolayer and/or alternating layers optionally with varying chemical composition. To reduce friction, a top outer layer comprised of molybdenum disulphide; molybdenum disulphide and transition metals, or any combination thereof; carbon; carbon and transition metal carbides, or any combination thereof; carbon and a transition metal, or any combination thereof; and/or carbon nitride may be either co-deposited as a single layer or deposited in multiple or alternating layers to the coating. The coated carbide tap of the invention can be used at cutting speeds at least three times faster than conventional taps without chipping or breaking the tap.
