摘要： A self-aligning tap is used to produce correctly aligned new threads in an existing smooth bore hole. The design of the tap's shank, flutes, and cutting surfaces is that of commonly used existing taps. The flat end of the tap—the end that enters the existing bore hole—contains a threaded bore. A removable pilot that aligns the tap to the axis of the existing bore consists of a cylindrical body with a diameter slightly smaller than the existing bore hole, and a length no greater than the diameter of the major diameter of the tap. The upper end of the cylindrical pilot—the end that shoulders against the tap—comprises a threaded stem whose thread pitch matches that of the tap end's bore, and whose length is slightly less than the tap end bore's depth. Once the cylindrical pilot's stem is threaded into the tap end's bore and the resulting assembly is placed into the existing bore hole, it serves to align the tap so that its cutting teeth produce pilot threads which are accurately aligned to the existing bore hole's axis. Once the pilot threads have been produced by rotation of the tap, the tap may be removed from the existing bore hole, the pilot detached by unscrewing it, and the tap reinserted into the newly formed pilot threads. Further rotation of the tap completes the tapping operation of the existing bore hole to the desired depth.

摘要： A cutting tool that includes an elongate body that has a forward end and a rearward end. The elongate body has a fluted portion that beginning near and extends in a rearward direction from the forward end. The fluted portion has a flute that defines a cutting edge. The flute presents a concave cutting face wherein the concave cutting face is defined by a first radius. The flute further presents a concave core surface adjacent to the concave cutting face wherein the concave core surface is defined by a second radius. The flute presents a convex heel surface adjacent to the concave core surface wherein the convex heel surface is defined by a fourth radius.

摘要： The present invention relates to a thread cutting tool with a shank and a cutting part, the cutting part having several cutting lands (3) with interjacent flutes and the cutting lands (3) having a starting taper (3a) and a guide part adjoining same. In order to produce a thread cutting tool with the features named at the outset which experiences less wear and must be reground less often than conventional threadd cutting tools of the type described previously, it is proposed according to the invention that the cutting teeth (5) have a chamfer (6) or rounded area (7) at their corners.
