  • I assume these are likely for a "ball mill" type device

    They are steel, and about 8mm diameter at max. I have nearly a pint of them. Did not check the hardness yet.

    CNC machines only go through the motions.

              When you hit one with a hammer, does it explode?

                Ball mill balls are usually round aren't they?
                The shortest distance between two points is a circle of infinite diameter.

                        I believe you are correct, I've run across those before as well. Although I can't remember where.
