ABSTRACT:
Turret-type tool holders for metal lathes, especially when used for production, conventionally have no vertical adjustment for the individual tools (e.g. tool bits). To provide for such adjustment, a first member which rests on the base of the tool holder has an arcuate surface and a second member with complementary arcuate surface rests on the arcuate surface of the first member. The tool rests on the second member. Two conventional tool holder set screws engage the top of the tool to clamp the assembly in adjusted position. By tightening one screw and loosening the other, the tool and second member "rock" relative to the first member to adjust the elevation of the working tip of the tool.
