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.

Re: Atlas quick wheel
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
