Sure would be nice to have a rotary tool add-on...

1. That holds the rotary tool stationary.

wheel (or other attachment).

Not sure of exactly how you want to cut the socket. But I have made Vee blocks out of wood and think you could make a rotary tool add on out of wood that would do what needs to be done.

Pallets are often made of oak which works well.

Of course if you have a table saw to make the add on, you can probably mount an abrasive disk on the table saw and cut with that.
