Abstract
Since the chip-breaking grooveis cut in the inner peripheral surface of the prepared holeby compressing the chip-breaking toolinto the prepared holeprior to the tapping process (the cutting process of the female thread) by the cut tap, the chip can be securely broken by the chip-breaking grooveand well discharged even in the case that the workis made of the material having the high ductility. Accordingly, for example, as shown in FIG., it is possible to prevent a lot of long connected chips from entwining the tap, it is unnecessary to monitor the tapping work, and it is possible to achieve a complete automation (an unmanned work). Further, it is possible to inhibit the cut tap from being broken due to the pinching of the chip, and it is easy to execute a treatment such as a chip cleaning or the like.
