Abstract
Rotationally symmetrical bodies consisting of metal materials must often be provided with cylindrical drilled holes following a central and straight progression. These drilled holes extend in part over the entire length, so that drilling yields a tubular body. If drilled holes with a depth>10 times the average are needed, deep drilling machines are used. This drilling depth combined with structural details may give rise to deviations from the drilling axis and work piece axis. This may lead to scrap. Therefore, the invention proposes a core drill head or solid drill head that exhibits a directional controller for use in deep drilling machines.
