Abstract

The bit has a shaft extended conically and with sharp edges (like a milling cutter) over the screwdriving sector so that it can be used for countersinking a screw aperture without any other tool being needed. The shaft is extended over the insertion tip of the bit. Its edges are sharpened. It can thus be used as a countersinking tool to make a countersink to take the screw head.

Description

Die Erfindung bezieht sich nach dem Patentanspruch auf eine Erweiterung des herkömmlichen Schrauberbits, (Ein­ satz in Schraubenmaschinen und Handschraubendreher zum Eindrehen von Schrauben mit unterschiedlichen Kopf­ ausbildungen) indem, über der Einsatzspitze des Bit der Schaft erweitert wird, dessen Kanten geschärft werden und somit gleichzeitig als Senkwerkzeug für den Schraubenkopf dient.The invention relates to the claim an extension of the conventional screwdriver bit, (a set in screw machines and hand screwdrivers for Screwing in screws with different heads training) by, over the bit's tip the shaft is expanded, the edges of which are sharpened be and at the same time as a sinking tool for the screw head serves.

Ausgegangen von dem derzeitigen Stand der Technik wird dabei von:Based on the current state of the art from:

  • 1. Herkömmlicher Schrauberbit mit unterschiedlicher Ausbildung der Adapterspitze.1. Conventional screwdriver bit with different Formation of the adapter tip.
  • 2. Senkwerkzeug um ein Bohrloch in alle möglichen Ma­ terialien im oberen Bereich konisch zur Aufnahme des Schraubenkopfes zu vergrößern.2. Countersinking tool around a borehole in all possible dimensions materials in the upper area tapered for admission to enlarge the screw head.
