Pick up some DeWalt brand Cobalt drill bits, they seem to cut through anything. I bought mine in a yellow case at Lowes and have been very pleased with them. I'm not sure if all Cobalt bits are created equally, but a buddy specifically recommended the DeWalt brand after trying a few others. They were a bit expensive, but they sure work (cut) great.
I think Shine has some good advice but then again he has been in the business of fixing other folks mistakes. I agree with Jim and Eliot that using extraction bits have always been our solution to a broken bolt and after using Sears and Dewalt, I would choose the Dewalt Cobalt.

if i can get to it and get a good center punch. i will use my backouts but many times you cant get a good center or even a flat surface. then i use the nut. i just set it in place and weld on the bolt and bring it up flush with the top of the nut. heating it also breaks rust loose by expanding it. . tight a little first then back it out.

we have used ez outs in the past with pretty good results. But some times a pain in the butt to get centered in tight spots. I like the nut welded.I will have to try that myself.
Anyway back to my point. I prefer to get the part unbolted and pull the part over the broken bolt leaving the broken bolt in place( If you have the space) Then we will us a stud extractor to pull the broken bolt out.
I had heard a twist on the welded nut trick-- 1st weld a washer over the broken stud-- makes it easier to get inside. Then weld a nut on top of the washer... MC

I have done it like italianguy63, but then welded the outside of the nut to the washer. Make certain you leave room on the nut to place the socket or wrench. Pool your weld around the nut and close to the washer and not much up the sides of the nut.
