Trying to be the bloody DIY mechanic that I make myself out to be, I managed to get myself into a pickle. Honda Jazz, trying to remove the final security bolt that secures the airbag on the steering wheel and i managed to damage the head bad enough that it will no longer turn. The bolt in its entirety is still intact but without means to put something into the head to turn it. I've tried drilling it only to leave a dent in the bolt. It ruined most of the drill bits I had which were appropriate for the job. I even tried calling Thread Doctor services LTD and they outright refused to do it because they've done something similar and it was too much hassle for them and they will not repeat. I really don't know what to do now. I was contemplating buying some expensive top quality drill bits and just annihilate it, but I don't even know where to start.... Any suggestions?
