A telescoping die holder apparatus a having a outer covering shell with a tapered rear morse into which a shank is fitted. This shank is associated with a biasing member and is reciprocally mounted to the shell by two retaining pins. Each of the pins extend through the shell into one of the four spaced shank slots that run lengthwise in the shank. Each shank slot is closed at one end and opened at the other end. At their opened ends the slots have outwardly opening chamfer rear ends. One end of the shank allows for a replaceable held die that is used to engage a rotatable work piece stock. At the shell's opposite end, a morse tapered end on the shell fits in the lathe's tail stock. An front optional adaptor can be placed in a large inner diameter opening in an enlarged front end of the shank and is used to accommodate a smaller sized die. The entire telescoping die holder is non-rotatable, including any of its parts, as the lathe turns the retained work piece stock and the stock engages the shank's retained die.
