Claim 0:
1. Drill rod element or drilling tool having a drill rod coupling,
wherein the drill rod coupling is provided with
a sleeve shaped coupling receptacle, which is arranged on a first drill rod element or drilling tool,
a pin shaped coupling member which can be inserted axially into the coupling receptacle to form a torque proof connection for conjoint rotation, and which is arranged on a second drill rod element or drilling tool, and
at least one locking bolt which is directed transversely to the axial coupling direction and extends, in a locked coupling position, between the coupling receptacle and the coupling member into a locking recess,
wherein the locking bolt is mounted so as to be radially adjustable between an unlocking position and a locking position,
characterized in
that the drill rod coupling can be used for coupling between the individual drill rod elements, or between a drill rod element and the drilling tool,
