I just experienced the modification of a socket, albeit one with an integral U joint. While it was machineable (I had to drill and tap a couple of 10-32 threads in the sides), what I discovered was that they are likely nitrided. The center drill I used for spotting was dulled immediately, so I hand ground a spade drill from a piece of round carbide scrap I had on hand, which had no trouble penetrating the hardened skin. Once that was accomplished, opening the holes and tapping were not an issue.

Harold, what does it mean when you say the socket might be ‘nitrited’? I assume some form of coating, but what would a nitrate coating consist of?

Also, I wonder if these sockets might be case hardened and seriously passivated through some chemical immersion process, and or chromed to prevent rust? Iam curious, as I’ve never seen a spec of corrosion on any socket, and some of mine are over 50 years old hard working mechanics tools, part of which lived on a fishing boat for decades in and near salt water.

I think Harold means "nitrided". https://en.wikipedia.org/wiki/Nitriding

Yes, that's what I meant. Thank you, John. :-)
