    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.

    摘要翻译： 切割龙头包括具有轴向前端和轴向后端以及中心纵向轴线的主体。 主体在轴向前端有一个槽纹部分。 槽纹部分包括从主体的轴向前端延伸并且终止于第一全切割螺纹的倒角的槽纹部分。 倒角的槽纹部分包括位于距离主体的轴向前端的第一距离的第一切割螺纹和位于距离主体的轴向前端的第二距离的第二切割螺纹。 第二距离大于第一距离。 倒角的槽纹部分的形状使得由第二切割螺纹去除的部分材料的厚度小于由第一切割螺纹去除的部分的厚度。 还公开了一种制造切割龙头的方法。

    摘要： A method of making a cutting tap includes the steps of: grinding a blank to form a threaded body portion at an axially forward end of the cutting tap, grinding one or more flutes in the threaded body portion to form cutting edges; grinding the threaded body portion to form a first cutting thread and a second cutting thread, the first cutting thread at a first distance from the axially forward end of the cutting tap, and the second cutting thread at a second distance from the axially forward end of the cutting tap; and grinding a chamfer in the threaded body portion such that a thickness of a section of material removed from the second cutting thread is smaller than a thickness of a section of material removed from the first cutting thread during a tapping operation.

    摘要： A drill-reamer tool comprises a shank portion and a cutting portion coaxial with the shank portion, the cutting portion having an operational portion comprising at least one twist drill spiral roughing cutting edge associated with a land margin, a land clearance and a flute. The cutting portion further comprises at least one spiral finishing edge interlaced with the spiral roughing cutting edge and having associated therewith only a land margin and a flute. The land margin of said finishing edge being provided with a plurality of reamer cutting edges spiraling in an opposite direction to that of the roughing cutting edge. The reamer cutting edges being configured to cut a larger hole than said roughing edge. The operational portion being dimensioned such that during operation, both the roughing cutting edge and the reamer cutting edge are simultaneously operative.
