Description

Die Erfindung betrifft einen in eine Bohrwinde einsetzbaren Steinfliesen- und Wandplattenbohrer, Die Erfindung besteht darin, daß dieser Bohrer aus Flach- oder Hohlstahl in rechtwinklig gezogener Form angefertigt ist, und daß er in an sich bekannter Weise an den beiden Enden durch entsprechende Zurichtung geradlinige und senkrecht zur Längsrichtung des Bohrers verlaufende Schnittflächen besitzt, welche etwa dem Durchmesser des Bohrloches entsprechen.The invention relates to a stone tile and wall plate drill that can be used in a drill winch, The invention consists in the fact that this drill is made of flat or hollow steel is made in a right-angled form, and that it is in a manner known per se at the two ends by corresponding Finishing has straight and perpendicular to the longitudinal direction of the drill cut surfaces, which about the Corresponding to the diameter of the borehole.

Die vorstehende Anordnung hat den Vorteil, daß der Bohrer nicht, wie bisher, mit einer Spitze in die zu bohrenden Fliesen oder Platten eindringt und zentrisch tangential schneidet, wodurch ein Ausbrechen der Bohrränder an dem bearbeiteten Material kaum zu vermeiden ist, und wobei weiterhin das Abraummaterial aus dem Bohrloch durch den Bohrer seitlich verdrängt wird und nur schwer aus der Bohröffnung rechtzeitig auszuräumen ist.The above arrangement has the advantage that the drill does not, as before, with a tip penetrates the tiles or slabs to be drilled and is tangential in the center cuts, as a result of which the drilling edges on the machined material hardly break out is to be avoided, and wherein the debris from the borehole continues through the Drill is displaced laterally and difficult to clear out of the drilling opening in time is.

Der Bohrer nach der Erfindung schrammt von Anbeginn des Bohrens an mit seiner geradlinigen, zur Plattenoberfläche parallelen Schnittfläche das Material aus dem Bohrloch. Zum Entfernen des Abraumes aus dem Bohrloch ist hierbei genügend Platz vorhanden, weil der Bohrer aus Flachstahl angefertigt ist, und durchgehend nur sehr wenig Raum im Bohrloch einnimmt. Ein Springen des bearbeiteten Materials sowie ein Bröckeln der Bohrränder wird vermieden. Es sind schon Bohrer anderer Art bekannt, welche an beiden 'Enden Schnittflächen besitzen und nach -dem Stumpfwerden der einen Schnittfläche umgedreht und mit dem anderen scharfen Ende weiterbenutzt werden können. Der Bohrer nach der Erfindung hat aber außer den obenerwähnten Vorzügen noch den Vorteil, daß selbst nach Stumpfwerden beider Schnittflächen, infolge der leicht vorzunehmenden, einfachen Abschärfung an beiden Enden ein Nachschärfen des Bohrers an Ort und Stelle, also am Arbeitsplatz, erfolgen kann, ohne daß hierzu besondere Fertigkeiten und Kenntnisse notwendig sind, wie bei den bekannten Bohrern. i'**·The drill according to the invention scratches from the start of drilling with his straight cut surface parallel to the plate surface removes the material from the borehole. There is enough space to remove the overburden from the borehole because the drill is made of flat steel is made, and consistently takes up very little space in the borehole. A jumping of the processed material as well crumbling of the drill edges is avoided. Drills of other types are already known which have cut surfaces at both ends and after becoming blunt the one cut surface turned upside down and used with the other sharp end can be. The drill according to the invention has, in addition to the advantages mentioned above, the advantage that even after both cut surfaces become blunt, due to the easy to make, simple sharpening at both ends a re-sharpening of the drill on the spot, in the workplace, without the need for special skills and knowledge are necessary, as with the known drills. i '** ·

Es ist ferner bei aus Rundmaterial her: gestellten, nur einseitig benutzbaren Bohrein bekannt, die Schnittfläche am Ende geradlinig und parallel zur Oberfläche des zu bearbeitenden Werkstückes herzustellen. Bei diesen Bohrern nimmt aber die Querschnittsfläche des' Bohrers von der Schnittfläche ausgehend stark zu; und die obenerwähnten Vorteile des schnellen und einfachen Anschärfens, des einwandfreien Ausräumens des Bohrloches sowie das aufeinanderfolgende Benutzen der an den beiden Enden vorgesehenen Schnittflächen sind bei den bekannten Bohrern dieser Art nicht vorhanden.It is further at from round material Manufacturer: provided, on only one side usable Bohrein known, straightforward and make the cut surface at the end parallel to the surface of the workpiece to be machined. With these drills, however, the cross-sectional area of the drill increases sharply starting from the cut surface; and the above-mentioned advantages of quick and easy sharpening, the proper clearing of the borehole and the successive use of the cut surfaces provided at the two ends are not present in the known drills of this type.

Von den beiliegenden Abbildungen stellt , α den Bohrer aus Flachstahl, b aus Hohlstahl dar. c und d sind die beiden abgeschärften Enden mit den Schnittflächen.Of the enclosed figures, α represents the drill made of flat steel, b of hollow steel. C and d are the two sharpened ends with the cut surfaces.
