I'm no engineer, but there's no way anybody could convince me that an out of round inside the lugs, at the wheels center could possibly effect balancing at the measurement levels of a tire shop. the rotational mass at the center is so small, that it wouldn't be a difference.

By using a mounted point in a grinder, you are spinning a stone that is nearly the same size as the hole you're looking to achieve.


Can you elaborate on this? The way you describe it make little sense to me. Most grinders are right angle drive.
