摘要： A method for producing a tapped bore in a workpiece with a tap drill bit, which, at its drill bit tip, has a primary cutting edge and a thread profile trailing in a tap drilling direction. The method has a tap drilling stroke, in which the tap drill bit is driven into the workpiece with a tap drilling advance in the tap drilling direction and at a tap drilling rotational speed synchronized therewith, and the tool-primary cutting edge produces a core-hole bore, and the thread profile of the tool bit forms an inner thread at the inner wall of the core-hole bore. In the tap drilling stroke, shavings are produced, which are conveyed in a shavings discharge direction, which is oppositely directed to the tap drilling direction, out from the tapped bore and collide here with thread flanks of the inner thread that face the shavings that are discharged.

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.
