Abstract
A tool for producing a thread such as an internal thread, can include at least one cutting region having at least one cutting edge and at least one thread-forming region. In general, the cutting region(s) and the thread-forming region(s) are coupled or connected to one another in such a way that they are rotatable or rotate together about a tool axis. In addition, at least one cutting region is at least partly formed on a front-face tool end and/or adjacent to a front-face tool end. Furthermore, a front-face recess that is configured for receiving chips is formed on the front-face tool end.
