Broken bolt extractor in bolt nightmare

[timsrv]

The broken extractor is long gone.
At this point Im just trying to get through the bolt.

That sucks. I've never had problem drilling through standard bolts, but easy-outs are are near impossible to drill (that was my initial concern). I'm thinking there must still be some easy-out left in the hole. I assume you're using a high quality cobalt??? Here's the ones I'd recommend:

things have gone from bad to complete and utter hell after I drilled all the way through the bolt and got a much larger, much deeper, and much harder (undrillable) bolt extractor stuck in the bolt.



I can say that at least I tried but at this point I might have to just swap out the head.
