Made from around 1947 until the late 1950s, the 8" x 18" Tool and Die Milling machine was built in two very similar models - a Mk. 1 until 1955 and a later, short-lived Mk. 2  from 1956 to 1959. The newer version had an altered main column casting, built-in electrical controls and other minor modifications. To reduce costs, the model was finally dropped and the special head and ram unit made available for fitting to a modified version of the Toolmaster and sold as the Contourmaster.
The  two early versions of the "Tool & Die" can be immediately distinguished from the "Toolmaster" modified type by their use of V instead of right-angled edges to the ways for the table's cross feed..
