Abstract: For producing bores, a fixture is used on which one of the vise-grip wrens 10 can travel in the longitudinal axis 17 of the clamping mount 2 and is correspondingly arranged in a movable way with the swiveling and traversable drum magazine 6. The interior 9 and exterior tubes 8 can be removed radially from the drum magazine 6 and are held by clamps 27, 28, with the swiveling and traversable drum magazine 6 being equipped with a clamping roller design 20 which raises the interior tubes 9 and lowers them into the exterior tubes 8 so that they, in combination, can then be swiveled into the drilling axis 26 in order to be connected with the existing boring rod.
