There seem to be frequent discussions about how to remove damaged bolts/screws.
The methods often involve drilling the screw & application of some form of easy out. The easy out is not a very good tool. The tool is tapered & provides a wedging action. This action also expands the screw & makes it even tighter in it's hole. To make things worse, it is quite brittle & easy to break.
I have found that drilling the screw with a left hand drill bit in a reversing drill usually causes the screw to back out before the drilling is even completed.The drill digs in without expanding the screw shank & turns it in the removal direction.
Left hand drills are available in various sizes at many tool stores. I've not had to use an easy out since getting a LH drill set.
