<p>A plurality of cutter tool holders are mounted to a milling cutter head by tongue and groove connections. Each connection comprises a groove formed in the cutter head and a tongue formed on the tool holder. The groove has an undercut portion and an enlargement at one end. The tongue includes a projection which can be inserted into the enlargement and then into the undercut to prevent, via wedging action, dislodgement of the tool holder. The groove and tongue each includes a side wall which is straight along its height.</p> |
