I can give you ten. I'll settle for one
Thick tube. Need a threaded through hole from OuterDiameter to InnerDiameter. That hole needs to not go through the whole tube only one wall. Hence I'd benefit from being able to link it to the inner surface of the tube.
You can have this situation with all kind of cases like boxes, engine housing, etc., where you want to go through the first wall, but never through all.
Besides that from a more general view, a hole is a special kind of pocket and can well provide the same types. (I don't see the "two dimensions" though).
