>It doesn't really matter if the security hole is centered
Alright. Great news.

I was messing around more with my bits. On the left is my trusty Victorinox Cybertool. My main torx bit. Look how beat to shit it is. You can see the faint circular imprint because I've managed to force it on few security bits over the years.
The rest of the bits on this 115 set actually look pretty well machined. It's just for some reason Chinese machinists can't align the hole properly. Maybe it doesn't matter that much like anon said so they don't bother to.
The new one on the right has survived a basic test of (un)screwing my multitool. The bit didn't melt like butter as I was afraid it might.
