Werkzeug zur Bearbeitung von Bohrungswandungen, insbesondere Durchgangsbohrungen mit hoher Oberflaechenguete

The invention relates to a process and a tool for the production of drill holes, whereby, during a feed movement of the tool with the first cutting parameters, the general production and a rough grinding preparation of the drill hole are performed by a first cutting facility provided at the front end of the tool and, during a return movement of the tool, a finish grinding machining of the drill hole takes place by a radially adjustable second cutting facility provided at the circumference of the tool with the second cutting parameters different from the first cutting parameters. The two cutting facilities can have a geometrically undefined cutting geometry.
