Description

Es sind bereits Bohreinrichtungen bekannt,There are already drilling devices known

die zum Nachbohren von ausgebohrten Löchern dienen und in einer runden Scheibe bestehen, die derart in dem Schafte eines Werkzeughalters gelagert sind, daß der Radius der Scheibe in der Ebene der Schaftachse liegt.which are used to re-drill drilled holes and consist in a round disc, which are mounted in the shank of a tool holder that the radius of the Disk lies in the plane of the shaft axis.

Diese Einrichtungen arbeiten ähnlich wie Reibahlen. Die kreisförmig verlaufenden Schneiden dieser Werkzeuge liegen nicht inThese devices work in a similar way to reamers. The circular ones Cutting of these tools are not in

ίο einer Ebene.ίο one level.

Demgegenüber besteht die Erfindung in der besonderen, im Anspruch näher gekennzeichneten baulichen Ausgestaltung eines solchen scheibenförmigen Werkzeuges.
Die Zeichnung veranschaulicht die Erfindung in einem Ausführungsbeispiel.
In contrast, the invention consists in the special structural configuration of such a disk-shaped tool, which is characterized in more detail in the claim.
The drawing illustrates the invention in one embodiment.

Fig. ι und iä zeigen das Messer im Schnitt und in der Aufsicht;Fig. 1 and iä show the knife in section and in supervision;

Fig. 2 zeigt das Messer im Schnitt und 20- beim Arbeiten, undFig. 2 shows the knife in section and 20- while working, and

Fig. 3 zeigt die an sich bekannte Anordnung'des Messers am Werkzeughalter.Fig. 3 shows the known arrangement'des Knife on the tool holder.

Das am Schaft b befestigte Messer α hat Schneidkanten c, die in der Ebene J-I liegen. Um die Schnittkanten denen des Spiralbohrers gleich zu gestalten, sind die Nuten d, e eingefräst,. die beiderseits bis zur Mitte . (s. Fig. ia) der Scheibe verlaufen. Um rechts und links arbeiten zu können, sind die beiden gegenüberliegenden Schneidkanten versetzt zueinander angeordnet.The knife α attached to the shaft b has cutting edges c which lie in the plane JI. In order to make the cutting edges the same as those of the twist drill, the grooves d, e are milled. both sides to the middle. (see Fig. ia) run the disc. In order to be able to work right and left, the two opposite cutting edges are arranged offset to one another.

Die Wirkung des Werkzeuges ist hiernach ohne weiteres zu erkennen. Die in einer Ebene liegenden Schneidkanten müssen in gleicher Weise arbeiten wie ein Spiralbohrer oder -senker, da die Schneidwirkung dieselbe ist wie bei diesen. Es wird durch die Neueinrichtung ' ermöglicht, die Löcher auszubohren wie mit einem Spiralbohrer, oder aber auch die. Einrichtung nur wie eine Reibahle zu benutzen, während die bisherigen Einrichtungen mit Messern von rechteckigem oder trapezförmigem Querschnitt lediglich zum Aufreiben dienten und ein Ausbohren mit ihnen nicht möglich war. '45The effect of the tool can then be seen without further ado. The one in one Cutting edges lying flat must work in the same way as a twist drill or countersink, since the cutting effect is the same as with these. It will be through the refurbishment 'enables the holes to be drilled out as with a twist drill, or else also the. Device only to be used like a reamer while the previous devices with knives of rectangular or trapezoidal cross-section only for reaming served and drilling out with them was not possible. '45
