Exzentrischer Bohrmeissel für Tiefbohrungen.
Den Gegenstand vorliegender Erfindung bildet ein exzentrischer Bohrmeissel, welcher vermöge seiner Form einerseits ein lotrechtes, rundes Loch, andererseits ein solches von
EMI1.1
bohren gestattet.
In der Zeichnung ist eine beispielsweise Ausführungsform des Ernndungsgegenstandes
EMI1.2
Der Schaft 1 des Meissels ist oben rund ausgebildet (2) und mit einem Gewinde.'5 versehen, welches in die Muffe des Gestänges eingeschraubt wird. Die Meisselschneide 4 erhalt eine derartige Form, dass dadurch beim Bohren auf der Bohrlochsohle ein Materialzylinder bzw. ein abgestumpfter Materialkegel 5 entsteht, welcher von der Grösse des durch die Teilschneiden 6 und 7 gebildeten Winkels abhängig ist. Dieser Zylinder oder Keg !'1 bietet dem Meissel die nötige Führung, wodurch stets ein senkrechtes, rundes und entsprechend weites Loch gehohrt wird.
Der exzentrische Teil der Meisselschneide 8 wirkt

Eccentric drill bit for deep drilling.
The subject of the present invention is an eccentric drill bit, which by virtue of its shape on the one hand has a perpendicular, round hole, on the other hand one of
EMI1.1
drilling permitted.
In the drawing is an exemplary embodiment of the subject matter
EMI1.2
The shaft 1 of the chisel is round at the top (2) and provided with a thread, which is screwed into the sleeve of the rod. The chisel cutting edge 4 is given a shape such that a material cylinder or a truncated material cone 5 is created during drilling on the borehole bottom, which is dependent on the size of the angle formed by the partial cutting edges 6 and 7. This cylinder or keg! '1 offers the chisel the necessary guidance, whereby a vertical, round and correspondingly wide hole is always drilled.
The eccentric part of the chisel edge 8 acts
