Ed: I think shell mills normally have a key slot and counter-bored hole in them for mounting on a stub arbor. They are used more like an end mill.

Tom,

Unless my eyes are failing me, a distinct possibility, the picture shows a keyed bore. Maybe it's missing the counterbore to make it a true shell mill. Doesn't really matter. It's a mill of some sort.

Ed,

The key in a shell mill is actually a sideways slot, not an internal key. One is shown below along with a shell mill holder.
