This is a set of tools for using 5C collets in the Shopmaster Mill Turn machine. The set consists of 2 5C collet blocks, 1 square for use with a 4 jaw chuck and 1 hex for use with the 3 jaw chuck. There is a drawbar that fits through the spindle to tighten the collets which has a knurled handwheel and a rotating sleeve so the drawbar can be loosened and tightened without friction against the end of the spindle. Contains 3 basic collets 1/4, 1/2, 3/4.
The Standard draw tube is 1.375" diameter and threaded to fit the external threads of a 5C collet. If your lathe has a through hole of this diameter or larger, the draw tube will work.
For Shoptask and Shopmaster machines or other brands with the 1.065" through hole, a draw tube of 1' diameter threaded to fit the internal threads of a 5C collet would work. You would need to fabricate a drawtube.
