This is a MAZAK style VDI40 lathe live offset tool. It holds an ER32 collet. Please look at the photos carefully. Spins freely by hand. There is some light surface rust spots. There is an ER16 collet holder in the ER32 collet. I don’t have the wrench to pull it out. Even if I pulled it out – I don’t need it. If you don’t see it in the photos… It is not included.
