摘要： It is an object of the invention to provide a thread-forming tap to which a chamfer can easily be mounted, and a general threading method. The thread forming tap of the invention has a threaded portion comprising a tapered chamfer and a parallel threaded portion which is formed continuously with the chamfer. A depth of root of the chamfer is set equal to that of a root of the parallel threaded portion constantly.

摘要： A tap having a reamer edge which is provided at a chamfer part, so that when the thread forming tap is pulled out after the internal thread is formed, a seam portion present at the crest of the internal thread is cut off, whereby even in a blind hole, formation of internal thread and cutting of the seam portion are performed in a single process, and formation of an internal thread and processing of an inside diameter portion are achieved in a single process to obtain concentricity in line with each other. Further, even if there is a deviation in diameter of the hole before threading, the inside of the internal thread is processed to a constant value.

摘要： A cutting tap comprises a threaded portion including a lead whose thread diameter gradually decreases toward a front end of the lead, a complete thread portion continued from the lead, and four flutes arranged at equal intervals in a circumferential direction. In the cutting tap, a first cutting edge portion for processing a prepared hole is formed at a front end surface of the lead, and a second cutting edge portion for finishing a minor diameter of an internal thread is formed in a part of an outer periphery of the complete thread portion, the second cutting edge portion being one or more pitches long. The cutting tap can perform processing of a prepared hole, tapping, and finishing of a minor diameter by a single step, and can also perform tapping even if a prepared hole for an internal thread is a blind hole or the like and does not have enough space.
摘要翻译：切割龙头包括螺纹部分，其包括引线，螺纹直径朝向引线的前端逐渐减小，从引线延续的完整螺纹部分和沿圆周方向等间隔布置的四个凹槽。在切割龙头中，在引线的前端面上形成有用于加工预定孔的第一切削刃部分，并且在外周的一部分中形成用于完成内螺纹的小直径的第二切削刃部分的整个螺纹部分，第二切削刃部分是一个或多个间距长的。切割龙头可以通过一步进行预制孔的加工，轻敲和小直径的加工，并且即使内螺纹的预定孔是盲孔等并且没有足够的，也可以进行攻丝空间。
