What did I just buy

Cornwell 1/2” drive socket with multiple inserts 5/16” to 1/2”. Inserts have rollers. What the heck is this

Looks like a stud remover.

I never would have guessed that.

Grab a correct sized bolt, insert and turn counterclockwise and it should grab.

Concentric type. You have the complete set. They came in a little metal box. I traded mine with a near complete master wrench kit to Unaiu, but pics and catalog excerpt are posted in the Cornwell thread. Go to the Index in the Sticky. Posts #33 and #34.

Thank you so much, you guys are a wealth of information. It did come with the little metal box. I just didn’t post pictures of it
