If it's only one, how about using a grindstone in a Dremel tool?
I wouldn't think the socket would be case hardened; it's not a wear
issue. I'd assume the material would be hard all the way through.
If the socket IS case hardened, then the case should only be 20 or 30
thou deep.

One other thought: Don't break the set up. Get a cheap set to do this
to, or do as I do:
Get just the socket you need at a flea market or at any Pawn Shop.

I take it that it's case harden as my drill bits don't even scratch
the surface.

Thank you all in advance.
