Description
Das Bohren von Stein, Mineralien,-Erzen, besonders von Mauerwerk macht mit den bekannten Bohrern Schwierigkeiten, Mühe und Verdruß, hauptsächlich, wenn es sich um frisch aufgeführtes oder altes Mauerwerk handelt; so fällt fast immer beim Durchkommen. des Bohrers durch die Wand ein Stück Putz heraus, wenn nicht gar der letzte Mauerstein mit herauskommt.The drilling of stone, minerals, ores, especially masonry makes Difficulty, trouble and annoyance with the known drills, mainly when it is freshly laid or old masonry; almost always falls like this in getting through. a bit of plaster through the wall, if not at all the last brick comes out.
Vorstehende Übelstände beseitigt der Erfindungsgegenstand. Dieser besteht aus einem Stahlstab A von der Länge des zu durchbohrenden Materials und einem Durchmesser D, welcher an einem Ende etwa auf 15 D Länge, 2 D Breite und % D Stärke flachgeschmiedet ist. Die Fläche B ist einige Windungen gegen die Bohrerdrehung, also bei rechtslaufenden Bohrern links gedreht. Der anschließende Teil C bleibt gerade und hat an den Seiten Schneidfasen. Das Ende C ist mit einer runden oder winkligen Auskehlung und ebenfalls mit Schneidfasen versehen, so daß die beiden äußeren Spitzen E, F als Schneiden dienen.The subject matter of the invention eliminates the above deficiencies. This consists of a steel rod A the length of the material to be drilled through and a diameter D, which is flat forged at one end to about 15 D length, 2 D width and% D thickness. The surface B is a few turns against the rotation of the drill, i.e. rotated to the left with clockwise drills. The adjoining part C remains straight and has cutting bevels on the sides. The end C is provided with a round or angled groove and also with cutting bevels, so that the two outer tips E, F serve as cutting edges.
Beim Bohren in Stein schaben die Schneidspitzen E, F kreisrunde Scheiben aus. Der feststehende Kern wird zerbröckelt. Das Gewinde B dient zur Führung und als Räumei. Der im Verhältnis zu den Schneiden E, F und dem Gewinderäumer B dünne Schaft A behindert die Drehbewegung des Bohrers selbst beim Durchbohren von meterdicken Wänden nicht, so daß ein Zurückziehen des Bohrers und Ausräumen des Bohrloches während des Bohrens kaum notwendig wird. Zur Betätigung der Drehbewegung genügt eine Handbohrmaschine, da die Bohrgeschwindigkeit und der Bohrdruck für Stein- und Mauerwerk keine große zu sein braucht. Auch die Abnutzung der Schneiden ist durch die federnde und elastische Anordnung des Bohrers gering.When drilling in stone, the cutting tips E, F scrape circular disks the end. The fixed core is crumbled. The thread B is used for guidance and as evacuation. The thin one in relation to the cutting edges E, F and the thread reamer B. Shank A hinders the rotary movement of the drill even when drilling meter thick Walls not, so that a withdrawal of the drill and clearing of the borehole during drilling is hardly necessary. A hand drill is sufficient to actuate the rotary movement, since the drilling speed and the drilling pressure for stone and masonry are not great needs to be. The cutting edge is also worn down by the resilient and elastic ones Arrangement of the drill small.
