Abstract

Bei vorliegender Erfindung handelt es sich das um, einen Schraubendrehereinsatz (1) mit einem Antriebsende (2), einem Schraubendreherende (4) und einem dazwischen angeordneten Torsionsschaft (6) so weiterzubilden, dass er mit einfachen Mitteln eine Andruckverstärkung in Folge von auftretenden Drehmomentspitzen unterstützt und es, wird vorgeschlagen, dass sich um den Torsionsschaft (6) eine helixförmige Drillzone (9) herumwinden soll, in welcher der Torsionsschaft (6) torsionsweicher ist als außerhalb der Drillzone (9).
