Abstract: A tool for holding a workpiece to be machined on a CNC lathe or other device which includes an integral or separately powered draw tube. The tool includes two rods which are spaced from but pivotally connected to the draw tube. The rods extend through a fixed tooling surface for releasable engagement with a clamping plate. When the rods are drawn in by movement of the draw tube, a properly positioned workpiece is retained between the tooling surface and the clamping plate for machining. Movement of the draw tube in the opposite direction releases the workpiece.
