摘要： A low torque tap includes a shank portion with a driving square and a thread cutting portion. The thread cutting portion includes a threaded body with one or more asymmetrical straight flutes that run essentially parallel to a longitudinal axis of the tap. The thread cutting portion also includes one or more short angular flutes or spiral points and a tapered chamfer. For tapping steel alloys, the cutting edges of the straight flutes and the spiral points have a rake or chordal hook angle of between about 5 and 15 degrees. For tapping ferrous materials, the tap is made from molybdenum-enriched high-speed steel and may be coated with a wear-resistant, friction-reducing layer. A second, outer layer, such as molybdenum disulfide, may be applied over the wear-reducing layer for further reduction in friction. For tapping non-ferrous materials, the tap may be coated with a layer of material containing carbon.

摘要： A cutting tap includes a body having an axial forward end and an axial rearward end. The body has a threaded body portion with spiral flutes adjacent the axial forward end, a cylindrical shank portion adjacent the axial rearward end. The threaded body portion includes a chamfered fluted section and a constant diameter section. The threads have a chamfer relief extending radially inward from the cutting edge to a heel of a land. The amount of chamfer relief reaches a maximum value at a point between the cutting edge and the heel, and then becomes smaller between the point of maximum relief and the heel of the land to provide a clearance that reduces the propensity of the tap to chip.
摘要翻译：切割龙头包括具有轴向前端和轴向后端的主体。主体具有螺纹主体部分，其具有与轴向前端相邻的螺旋形凹槽，与轴向后端相邻的圆柱形柄部分。螺纹体部分包括倒角的槽纹部分和恒定的直径部分。螺纹具有从切割边缘径向向内延伸到台阶的后跟的倒角浮雕。倒角减轻量在切削刃和跟部之间的点处达到最大值，然后在最大浮雕点和焊脚的跟部之间变得更小，以提供减小接头对芯片倾向的间隙。

摘要： A cutting tap includes a body having an axial forward end and an axial rearward end and a central longitudinal axis. The body has a fluted section at the axial forward end. The fluted section includes a chamfered fluted section extending from the axial forward end of the body and terminating at a first full cutting thread. The chamfered fluted section includes a first cutting thread located a first distance from the axial forward end of the body, and a second cutting thread located a second distance from the axial forward end of the body. The second distance is greater than the first distance. The chamfered fluted section is shaped such that a thickness of a section of material removed by the second cutting thread is smaller than a thickness of a section of material removed by the first cutting thread. A method of making the cutting tap is also disclosed.

摘要： A cutting tap that has an elongate tap body with a fluted section at the axial forward end thereof wherein the fluted section includes a chamfered fluted section and a finishing fluted section. Each cutting thread in the chamfered fluted section has a cutting face disposed at a cutting face angle that becomes more negative the more axially rearward the cutting thread is from the axial forward end of the chamfered fluted section. Each cutting thread in the finishing fluted section has a cutting face disposed at a finishing cutting face angle that is essentially equal. The finishing cutting face angle is more negative than the cutting face angle for the cutting thread at the axial rearward termination of the chamfered fluted section.

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.
