<p>The present invention provides a cutting tool assembly (10) comprising a tool shank (12) a pull rod (36) and a cutting head (46). The tool shank (12) has an axially extending elongated hole (18). A forward portion (20) of the elongated hole (18) being formed by first and second non-coaxial, partially overlapping, axially extending cylindrical bores (28, 30). The pull rod (36) has forward coupling portion (40) that cooperates with a rear-coupling portion (50) of the cutting head, forming a joint coupling region (52). The pull rod (36) and the rear-coupling portion (50) of the cutting head are retained in the elongated hole (18) in the tool shank (12) with the joint coupling region (52) situated in the forward portion (20) of the elongated.</p> |
