German term or phrase:Wendelgang
In a patent relating to a rock drill bit the following sentence occurs:
"Im wesentlichen verbreitet sich bei einem Wendelbohrer für Gestein längs der Drechachse die Breite des Rückens des WENDELGANGES in Richtung des Werkzeugkopfes."
I'm having trouble with Wendelgang and the Rücken part. Any ideas re: Wendelgang and Rücken would be very gratefully appreciated ...
