Along with a box full of other tooling, I also got these MT3 Arbors with my Mill. Does anyone know, on which machine type and what they are used for? There is no drawbar thread at the end and the OD is engraved on the shanks with high precision (in metric). My first thought would be some sort of test- or alignment bar, but what are the threads on the frontend for?
