ABSTRACT:
To produce a connection without play between the shaft or shank (3) of a tool head (1) and a corresponding bore (4) of a tool holder (2), the shank includes an abutment collar (5), an adjacent short conical portion (3a), a cylindrical pin portion (3b), and a guide portion (3c) at the end of the shank. The short conical portion adjacent the collar is slightly overdimensioned compared to a corresponding conical portion (4a) of the bore. When the shank is forced into the bore at least one of these parts is elastically deformed and the abutment of the shank comes into planar contact with an end face of the tool holder. The guide portion (3c) at the end of the shank may be either cylindrical or conical.
