Claims (2)

  1. Werkzeughalter für ein Bohrgerät, umfassend nahe an seinem Ende mindestens zwei radiale Hohlräume (2,2'), die jeweils an der Außenseite des Werkzeughalters und im Inneren seiner axialen Bohrung münden und dafür vorgesehen sind, jeweils als Aufnahme für eine Kugel oder einen Zylinder (6,6') zu dienen, wobei die Mündungsöffnungen der Hohlräume solche Abmessungen besitzen, daß die Kugel order der Zylinder von außen her in diese Hohlräume eingeführt werden kann, jedoch diese nicht nach innen in die axiale Bohrung verlassen kann und durch einen Ring (13) daran gehindert wird, nach außen zu entweichen, und mindestens ein Teil (3) aus einem harten Material, das in mindestens einem dieser Hohlräume (2,2') angeordnet wird, dessen Körper auf der einen, zur axialen Bohrung hin gerichteten Seite einen ersten vorspringenden Teil (11) in Form eines Steges aufweist, der mit dem Werkzeughalter und dem Ring (13) assoziert ist und als Antriebskeil dazu dient, gleichzeitig das Festhalten einer Kugel oder eines Zylinders (6,6') und des assoziierten Teils (3) zu gewährleiste, dadurch gekennzeichnet, daß sämtliche radiale Hohlräume (2,2') dieselbe Form besitzen und der Körper (10) die gleiche Form wie die Hohlräume hat, was ihm ermöglicht, sich dort ohne Spiel einzufügen, und er auf der Seite, die der Seite mit dem ersten vorspringenden Teil (11) entgegengesetzt ist, einen zweiten vorspringenden Teil (12) aufweist.
  2. Werkzeughalter gemäß Anspruch 1, bei dem der Körper des assoziierten Teils, folglich jeder mündende Hohlraum, die Form eines länglichen Kegelstumpfes besitzt, der erste vorspringende Teil (11) ein prismatischer Steg ist und der zweite vorspringende Teil (12) ein parallelepipedischer Steg ist.
