Abstract

Das Hohlbohrwerkzeug besteht aus einem Trägerkörper (1) und in dessen vorderes Ende eingelassenen Schneidsegmenten (3, 4). Die Schneidsegmente (3, 4) sind im Trägerkörper (1) der­ art versetzt angeordnet, dass sie wechselweise im wesent­ lichen die Innenkontur und im wesentlichen die Aussenkontur des Trägerkörpers (1) überragen. Durch die zwischen den Schneidsegmenten (3, 4) und der Bohrlochwandung bzw dem Bohr­ kern entstehenden Ringspalte (5, 6) ist eine gute Abfuhr des Bohrgutes möglich.
