Anchoring bolt drilling and setting apparatus, in particular for mining, with a mounting (10), on which a preferably hydraulic, rotary, in particular rotary percussion drill (11) is mounted in a longitudinally adjustable manner, having on the power take-off side a mounting for a plug-in stump end, the latter being held in the drill (11) by a holding device, e.g. a threaded cap (16) or the like, the plug-in stump (12) having wings (13) for transmitting the torque between the drill and the drill pipe or such like, and the end region of the p lug-in stump (12) pointing out of the drill having a thread (19) for connecting to a drill pipe or such like, characterized in that the end region of the plug-in stump (12) having a thread has at least two fitting surfaces (21, 37) which cooperate with at least two further fitting surfaces (29, 39) of an intermediary member (27), the fitting surfaces and/or their generatrices forming an angle of less than 90 degrees, in particular 0 degrees, with the drilling axis.
