What is the thinnist piece of metal an ER40 will hold so you can face it? It will be 25mm diameter, will it hold a 2mm thick disk with some sticking out to face it? The material will actually be brass. I don't have the collet or chuck yet so I can't check myself.

Couldn't you put a 25mm stub behind the disk to support it in the collet? Kind of as a stop for the disk.

Yeah, that thought had crossed my mind, just wasn't sure if there would still be enough for the ER to hold onto it.

Don't bore out the whole ER to 25MM. Instead cut it like a counterbore with a bottom as the stop.

Looks like a type of pot chuck. I've made them for my lathe when I need to hold something thin.

For just facing thin material I've had luck with facing off the end of a piece of bar stock in the chuck and super gluing the thin part to the end of it. Just take light cuts. A little heat or Acetone will remove the super glue afterward. Or use double stick (carpet) tape. If I needed to do a
bunch of parts though, I would go with the collet fixture.
