Orienting apparatus for turning tools

An orienting apparatus for arranging on a turning tool, for orienting a bore or depression to be introduced or for orienting a finishing step with respect to a normal to the surface of a workpiece, comprising a main body having a through-hole for receiving a tool shank or a tool tip in an orienting direction, and at least two probe elements for oriented support on the surface of the workpiece, wherein as a result of an orienting movement of the orienting apparatus with respect to the normal to the surface of the workpiece, all of the probe elements form an electric circuit between an electrical current source contained in the main body and a signaling device, said electric circuit being closed by a series circuit activated by one of the probe elements, in order to activate the signaling device by way of the closed electric circuit, such that, upon mechanical contact of all of the probe elements with the surface of the workpiece and movement of each of the probe elements by a distance in the normal direction to complete respective electric circuits, the signaling device is activated and an orienting signal is output, wherein:

• an electric switching point of at least a first probe element is positionally adjustable in the normal direction towards the surface of the workpiece, relative to the surface of the workpiece by means of a contact adjusting screw, such that the position of the first probe element can be set with respect to the surface of a workpiece, and
• at least one contact adjusting screw can be positionally secured via a locking screw.
