This is an expandable mandrel. We machinist use them mostly on the lathe to precisely hold difficult parts to machine. They are usually held in the chuck or a collet then machined to the dimensions needed for the project. This one has been machined, the link I am providing shows a new mandrel. There are hundreds of different kinds.
