摘要： A method for creating an inner thread in an opening of a body, using a thread cutter, including the following steps: a) the thread cutter having an axial lengthwise cutout adjacent to which there are blades that project radially outwards and that have cutting edges, is inserted into the opening, whereby several cutting edges arranged one after the other in the longitudinal direction are provided on the lengthwise cutout, which are offset with respect to each other in the circumferential direction, and which are pushed into the groove when the thread cutter is being inserted, b) the cutting tool is rotated by a maximum of 360° in order to create the entire inner thread in at least one projection next to the groove, whereby the cutting edges penetrate into the projection one after the other as the thread cutter turns, and c) the thread cutter is moved axially out of the opening.
