I crawled under my truck the other day and noticed that both of my tranny mount bolts were seard off...So i drilled the first hole, got my bolt extractor and it came out perfectly. On the second one the extractor broke off..:banghead:.....
I tried drilling the exctractor out but the bits that i had broke off too..:banghead::banghead:
Does anybody have any ideas, or know of some really good drill bits that might drill through the extractor...TIA!

Being the extractor is hardened steel, find a cobalt bit. Theyre expensive but theyre the only bit that will drill it. Also drill slow/ medium, not full speed.
