Before drilling go to Amazon or www.ezgrip.net and order a bottle of EZ Grip Friction Drops. If not working on an aircraft you should just order the Commercial Grade. It's the best way to remove a stripped/stressed screw.

From EZ Grip Friction Drops, at www.ezgrip.net One of many estimonials to us from a customers with a similar problem. Justin R says: August 15, 2016 at 2:52 pm I’ve tried everything I could find to help remove stripped screws… I was skeptical of the friction drop method. However, after trying it, I can tell you a huge fan! Spit/abrasive, valve grinding compound, and any other DIY friction drops are NOTHING compared to EZ Grip. Just to test, I stripped a Phillips screw until it was absolutely GONE, just a tiny bowl left with no channels for a screwdriver to catch on whatsoever, and with a couple drops of Ez grip and slow, heavy pressure from a a drill with Phillips bit and IT CAME OUT!! Amazing!!
