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 high durability taper tap for pipe threads which can cut threads in a pipe made of hard materials having hardness of approximately 50 HRC. The sum &Sgr;&ggr; of the width angle of cutters is large, approximately 130°, thereby achieving high strength and rigidity are achieved. Since rake angle of the cutting edge &agr; is approximately −20°, cutter angle &bgr; defined by the rake face and the peripheral relief becomes more than 90° so that the strength and rigidity of a cutting edge are enhanced. In addition, since a taper of the bottom of flutes is in a ratio of 1/16, approximately equal to that of the thread portion, the rake angle &agr; of all of the cutting edges 6 is uniform so that all of the cutting edges can equally cut the threads. Further, the diameter Df of the bottom of the flutes of the top end portion is approximately 60% of the smaller end of the thread portion, which is larger than that of the common tapping tool. Owing to this configuration, the taper tap for pipe threads having high strength, rigidity and hard wearing property can be achieved.

摘要翻译： 用于管螺纹的高耐久性锥形龙头，其可以在具有约50HRC的硬度的硬质材料制成的管中切割螺纹。 刀具宽度角度的总和大约为130°，从而实现了高强度和刚性。 由于切削刃α的前角约为-20°，由前刀面和周边凸起限定的刀具角度β大于90°，​​从而提高切削刃的强度和刚度。 此外，由于凹槽底部的锥度与螺纹部分的大小相等的1/16，所以所有切削刃6的前角α均匀，使得所有切削刃可以 同样切线。 此外，顶端部分的凹槽的底部的直径Df约为螺纹部分的较小端部的大约60％，大于普通攻丝工具的直径。 由于这种构造，可以实现具有高强度，刚性和耐磨损性的管螺纹锥形螺纹。

摘要： A pivoting split thread chasing die for rethreading and cleaning damaged or inhibited studs or bolts; and a method of manufacturing the die. The identical main body halves of the pivoting split die, when assembled together with an assembly pin form a pivoting split die with opposing front and rear faces and a hexagonal outside periphery. Threads are formed on the inside periphery of the pivoting split die allowing for engagement with the threads of a stud or bolt. One or more material reliefs are formed on the inside periphery of the pivoting split die to enhance the cleaning and rethreading ability of the pivoting split die threads. These reliefs also serve as points for which debris can escape while performing a rethreading procedure. To rethread or clean a damaged or inhibited bolt or stud, apply an appropriate lubricant to the area to be rethreaded or cleaned. Open up the pivoting split die and install around existing good threads of the stud or bolt and close pivoting split die until minimal closure gap exists. Select the appropriate wrenching tool and work the pivoting split die back and forth (counter-clockwise and clockwise) over the damaged or inhibited threads until the pivoting split die begins to move about the threads freely.

摘要： A tap having a main body having a crest, a heel, and an outer circumference is disclosed. The tap main body has a male screw part at the crest side. At this male screw part, a plurality of grooves opening to the crest and the outer circumference of tap main body is formed. A tap main body has a cutting edge at each ridge part defined by a wall of said plurality of grooves and an outer circumference of a male screw part. These cutting edges each have a crest part and a heel part. The crest part of at least one cutting edge has an axial rake angle which differs from an axial rake angle of the crest part of another cutting edge.

摘要： A tool for reconditioning or restoring the threads of externally threaded members, such as bolts, studs, and the like, includes, in one embodiment, a collet having a bore formed therethrough with a portion of the bore defining a guide surface, and a threading insert that includes thread cutting means. In order to recondition threads, the threading insert is selectively positioned along the longitudinal axis of the threaded member with the thread cutting means engaging the threads of the member. The collet is placed over the end of the member and positioned such that the threading insert is received within a socket formed in the collet thereby retaining the threading insert in place against the externally threaded member. Rotation of the tool relative to the threaded member causes the cutting means to recondition the threads. In one alternate embodiment, the cutting means are associated with the collet rather than with the threading insert.
