In a machine tool wherein a turrethead for holding a rotary tool is mounted on a ram capable of holding a turning tool, the ram is bifurcated to provide a pair of spaced-apart legs. The turrethead is mounted between the legs of the ram. Comprising a mounting body and a cutter affixed thereto, the turning tool is removably mounted under the ram and turrethead, with its mounting body in close contact with both of the ram legs and with the turrethead, and is thus adapted for heavy cutting work. For thus mounting the turning tool, one or more headed pull studs are formed on its mounting body and are releasably engaged within a mounting hole or holes formed in the ram legs and/or turrethead.
