I don't think it is a tool issue. It's more that the lens isn't glued down enough and comes loose and spins. If I'm reading the OPs post correctly.
If that is the case, then I don't know what to say, it happens occasionally to me too. But, only a couple in a hundred bulbs, so I toss them out and move on.
I guess you could put a little supper glue on them to help lock the lens in place..?
