ABSTRACT:
A deep-drilling tool, embodied by a tube provided with an internal passage and on the end of which a drill head is attached, the tube being divided into two tube sections, the rear one of which in the drilling direction has a diameter larger than that of the drill head. The entire drilling tool can accordingly be removed together with the drill head through a bearing or lubricating-oil supply device for replacement without disassembling the tool.
