EMUGE Taptor ® is a new internal threading technology developed jointly by EMUGE and AUDI AG. The threading tool combines a twist drill with a tap and results in a significant saving in machining time.

Taptor was developed to help achieve significant time savings in the production of internal threads in blind holes and through-holes. While the EMUGE Punch Tap and Speedsynchro® technologies generate time savings via shorter tool paths or higher cutting speeds, Taptor® achieves savings by reducing one working step.

With Taptor, the core hole and thread are produced simultaneously in one operation. The process is divided into two steps. In the first step, the movement of the tool corresponds to synchronous tapping. The drill feed per revolution therefore matches the thread pitch. In the second step, the tool cuts free at the drilling depth. And the thread teeth create a circumferential undercut.  Last, Taptor is retracted through the generated thread. The process can be used on any machine that is suitable for synchronous tapping, has a spindle with torque support and a suitable tool magazine for holding the Speedsynchro Taptor .
