Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bei der Zahnbohrerkonstruktion nach dem Hauptpatent ist angenommen, daß die Schneidflächen der Bohrerzähne hinter oder wenigstens senkrecht zur Mitte des Bohrerkopfes stehen, um die dem Werkzeug ein besseres Arbeiten nach vorn (Bohren) ermöglichenden, stern- oder kreuzförmig sich treffenden Schneiden, vor Kopf des Bohrers, zu erhalten.In the dental drill construction according to the main patent, it is assumed that the cutting surfaces the drill teeth are behind or at least perpendicular to the center of the drill head, to allow the tool to work better forwards (drilling), star-shaped or cutting edges that meet cross-shaped, in front of the head of the drill.

Die Schneiden sowie peripherisch besser schneidende Zähne werden aber auch dann noch erreicht, wenn die Schneidflächen der letzteren ein wenig nach hinten geneigt sind bzw. die Basis der Zähne ein wenig von der Senkrechten zur Mitte des Bohrerkopfes vorspringt. However, the cutting edges and teeth that cut better peripherally are also then still achieved when the cutting surfaces of the latter are inclined a little backwards or the base of the teeth protrudes a little from the vertical to the center of the drill head.

In der Zeichnung ist ein Zahnbohrer mit solcherart stehenden Zähnen in Ansicht von vorn (schematisch) dargestellt. Die mit a bezeichneten Zahneinschnitte sind die tiefergeführten und die mit b bezeichneten Einschnitte die in gewöhnlicher Weise durchgeführten. In the drawing, a dental drill with such standing teeth is shown in a view from the front (schematically). The serrations labeled A are the deeper the incisions and run designated b carried out in the usual manner.
