In the process and apparatus for removing the drillings from the drilling site of a drill described, removal is effected through a conduit, extending along the axis of a drill and possibly an adapter for a drilling machine, by a vacuum provided by a compressed-air stream traversing the removal conduit, said compressed air also serving to blow the drillings sucked into the conduit out of the conduit and away from the drilling site.
