If it's tight enough to brake off, an easy out probably won't work, but it's worth a try. Just be careful not to break it off or you'll have a bigger problem.
I've had good luck drilling it out and re-tapping to the appropriate size. Good luck! I hate when that happens.
Yea it didn't work I had to end up drilling thru it size at a time careful not to get into the original threads. And then taped it. I managed to save it and its still the same size threads
