Description

Das Vierkant an Steckschlüsseln;, die beim Festspannen von Bohrern, in Bohrköpfen benutzt werden, um die Spannbacken mittels einer Schraube anzuziehen, wird leicht beschädigt. Dann ist ein Abfeilen des Grates nötig, falls· das Vierkant gut eingepaßt war. Dadurch, nutzt sich, das Vierkant schnell ab. Das nicht oder nicht mehr gut passen.dje Vierkant wird aber stets das Vierkantloch inThe square on socket wrenches; used when clamping drills in drill heads to tighten the jaws with a screw is easily damaged. The burr must then be filed down if the square was fitted well. As a result, the square wears off quickly. That doesn't or doesn't fit well any more But square is always the square hole in

Die vorliegende Erfindung stellt sich die Aufgabe, durch, eine Vereinigung hier Abhilfe zu schaffen und die Lebensdauer des Schlüssels und der Schraube zu erhöhen.ίο widen the screw mentioned in the drill head. The present invention aims to remedy this situation by means of a union and to increase the service life of the key and screw.

Aufsteckschlüssel zeigen zwar nicht den in der Einleitung- dargestellten Übelstand, platzen aber dafür leicht auf. Der vorliegende Erfindungsgegenstand ist darum Aufsteckschlüssel und Einsteckschlüssel zugleich. Bei ihm genügt eine bereits praktisch leicht durchführbare Genauigkeit, um gegen Aufplatzen und Überdrehen gesichert zu sein. Dieser Umstand ist bei Bohrköpfen von Bedeutung, weil an der Peripherie eines Bohrkopfes wenig Raum zum Anordnen einsesi Schlüsselloches 1C oder Zapfens e zur Verfügung steht.Socket wrenches do not show the drawback described in the introduction, but they break open easily. The present subject matter of the invention is therefore socket wrench and socket wrench at the same time. With it, an accuracy that is already practically easily achievable is sufficient to be secured against bursting and overturning. This fact is important in the case of drill heads because little space is available on the periphery of a drill head for arranging a keyhole 1 C or pin e .
