Abstract
An anchoring rod for rock anchoring (self-drilling injection bolts), includes an outer thread for connecting the anchoring rod to a drilling tool via a coupling sleeve. The end of the anchoring rod, which is screwed into the coupling sleeve, comprises a section which has a reduced diameter in comparison with the outer diameter of the anchoring rod. The free end of the section of the anchoring rod with the reduced diameter comprises a bevel. An open space is thus formed between the inner surface of the coupling sleeve and the reduced diameter end of the anchoring rod. The space stops the anchoring rod from becoming stuck in the coupling sleeve, even when the end of the rod is plastically deformed during the drilling process, so that the anchoring rod can be unscrewed from the coupling sleeve without applying significant force.
