How to repair broke bolts in aluminum

There is a lot to be said for centering the drilled hole.
Bet you can knock that easy out loose with some patience and a punch by tapping it side to side.
The hardened metal of the tap should work loose in the bolt metal.
Just try and not knock it down in tighter.

You could also drill real small holes right next to the easy out and eventually work the metal out by drilling and collapsing the bolt metal in on itself.

Either way patience is your friend here.
