Welp, I broke off the bolt head of a 8mm bolt. What is the name of the tool that I can use to back out the rest of the bolt? I think I once saw a drill bit looking thing that digsinto the bolt and helps thread it out.

Purchase some left handed drill bits, I have some MAtco cobalts that are very nice, snapon and others sell them too. Then buy an EZ out, or Bolt extractor set. Make sure you get the square kind of extractors, the ones that look like drill bits don't work worth a crap.

It's called an "easy-out"... seriously.

I use a set of Craftsman extractors I bought from Sears that work great. Like the other guy said get the ones that are square looking not the drill bit kind.

ya there called easy outs, how deep is the bolt broken off? if you can get vise grips on it that might work also.

its flush ( Yea I live a ways out from a sears.. believe it or not

So I just ordered a set, as the lowes down the street only has the drill bit looking ones.

those work very well, good luck and make sure you drill the hole in the middle of bolt.

ok, so let me get this right

I need a set of left handed drill bits, so as to drill a starter hole in the 8mm bolt, and use the left handed ones as opposed to normal right handed ones.. so they have a chance to loosen the bolt vs tighten it.

then use the easy out bolt things.

you dont really need the left hand drill bits, but it does help. there have been times that i have been drilling out studs and and i just run the drill in reverse after drilling it a 1/4" deep and it comes out. i am a machinest so i see that stuff a lot, just take your time and it will come out
