If the nut is just turning (it is), will drilling the bolt not just make it spin really fast? Or will it still do the required damage eventually?
Place it on a bit of wood that will help stop the thing spinning oh and don't use the drill on full speed as you may end up spinning the chain ring across the room decapitating anyone close by.
