<p>The invention provides a simplified mounting device for connecting a rotary-cutter tool with a machine spindle. The mounting device is of two-piece structure, one piece constituting an arbor (10) connectable to the spindle, the other constituting a tool holding adapter (11). The adapter (11) is connected with the arbor (10) by means of a clamping bolt (13) centrally received within a central bore (26) of said arbor for the transmission of cooling medium to the cutter tool. A very good precision and centering is attainable at the mounting of the tool due to the provision of a cylindrical extension (16) on said adapter, which comprises two cylindrical portions (27, 28) with different diameters provided with a close interfit against complementary surfaces within said bore (12) in said arbor.</p> |
