Abstract
To provide for positive guidance of a bolt formed with a conical enlarged intermediate portion holding a cutter bit by resilient deflection of the bolt in an enlarged recess portion of the cutter bit, the enlarged recess portion is formed as an elongated portion adjacent a bore in which the bolt is threaded, the elongated opening being additionally formed with conical surfaces concentric with the bore so that, prior to resilient deflection of the bolt, the bolt is positively guided and, thereafter, the elongated opening permits deflection of the bolt, the length axis of the elongated enlarged portion being directed towards an abutment surface on the tool body to securely clamp the bit against the abutment surface and determine the direction of resilient deflection of the bolt.
