Highly likely we can get the remains of the bolt out, but it will of course entail at the very least, a transmission strip. You don't want to run the risk of any debris getting lost internally.
It's most likely that you can't just simply drill it out. It's too small, and if you slip, or even don't run down the centre of the bolt, you'll ruin the cases. The cases will probably need to be mounted in the mill, to hold them securely.
