what's your best broken bolt extraction tool, method?
Have you tried left hand drills?
Either way, soak it with lots of solvent ( I used PB Blaster) and tap it a bunch to loosen the bond it has with the metal it is bolted into. If you can weld a nut on it, that has always been best. The extraction stuff works good too. Just before the attempt, consider heating the metal it is stuck in.
thread is a total afterthought of a broken bolt in something else altogether. it just made me think that I haven't seen a recent thread on this in a couple of boards I read.
So, if we need a scenario, how about a broken head bolt? Bolt is inside the block bolt hole (to deep to weld), broken off uneven? I'm sure at some point we all go through this on something, automotive or not. If you have a great extractor tool, show us your weapon!

If it's deep and uneven using a centerpunch to leave a deep divot and very steady drill hand can do it. If you're used to drilling metal you can start the hole on an angle then gradually bring the drill up to vertical. This has worked for me in the past to get the hole centered so as to be able to use an easy out.
Pretty tricky trying to get the centre punch in the centre of the bolt,some of those bolts are as hard as the punch.I hear ya on correcting the drill angle.Slow as you go,that;s for sure.I have drilled out bolts to the point where all that is left is the thread and I was able to tap/fish out the thread.8)
how many times have you used care in getting the hole drilled, got the ez out started and SNAP?If it's deep and uneven using a centerpunch to leave a deep divot and very steady drill hand can do it.
