Worste thing you can do is snap a drill or easy-out in a bolt, you can't drill them out.

I work on motorcycles so have perfected various methods over the years to remove steel fasteners seized into aluminium. Out of all the tools the spline bits normally get the most seized out (along with heat).

If you can clamp the outside with mole grips, and turn these at the same time as the tool in the centre it gives you more chance!.
