Re: Drilling Out Screws
I do use a dremel tool to get either a nice flat top to drill into or slightly cupped if the fastener is larger. If there is plenty sticking out, I use the dremel to cut a slot first and try and back it out with a screw driver. If the fastener is seized, I skip that and go right to one of my Snap-on left handed drill bits. Usually, just the drilling action spins the fastener out without even having to use an easy out.
After drilling out about a half dozen bolts in an old Honda outboard, I was chatting with an old time mechanic and he told me if you coat the stainless bolts with Permatex #2 before you screw them into the aluminum, you'll never break off another bolt. I tried it and it worked. I was using the "Never Seize" type coating prior to that, but now if I'm screwing into aluminum, I use brown goopy/sticky permatex. Oh and if you get some of that on your fingers, alcohol cuts it.
