Removing broken bolts?

I had to fix this same problem 3 times on my son in laws XJ. The first time I used the reverse rotation drill bits (Tool center on 3rd west) and that worked fine for the holes I could reach. I had to use a 90 degree drill adapter. The best way I found to fix these was to bag the drill bits and CAREFULLY weld onto the end of the stud until I had a stub that I could get the vice grips on. This worked every time and I have since done the same thing on rusty bolts on my cj and as long as you take them out while they are still hot it works great.

Um, yeah. That's what my second post was all about... The question is, where do I get said LH drill bit? I've never seen one in any store I've been to.
they sell them at the left handed screwstick store! jsut kidding, EZ outs work if you use heat in the broke bolt after drilling the hole. tends to make the EZ out grip the metal better.

They're out! The first one came out with a left handed drill bit and a 90 degree drill adapter from Harbor Freight. The second one did not want to come out with that method, but I was able to weld a nut on the end of it and turn it out. Unfortunately one of my failed attempts left me with a nut welded to my small vice grips... :ugh:

Nothing a little grinder with a cut off wheel won't fix. :D :D :D

There is a specialty welding rod made just for times like this. I am unsure of the make and number but a good welding supply shop should have them. You just put a nut on top and use the welding rod to fill the gap till it gets up to the nut, the special flux on the rod protects the threads and the heat helps to break the broken part loose.
