I ordered the helicoil kit but I have to drive my car for work and I am not sure how I should go about moving forward. I can't get the bolt or bits out of it. Every time I try to drill it the bit slips and mangles the head. It's worst case scenario now. FML
Did you get it figured out yet? With drill bits sometimes you can hit them with a punch and shock them enough to get them loose... High quality drill bits are a must have especially when you're drilling into something that you don't want to replace. Drilling out a drill bit can be done, but it will take a lot of patience. Always make sure to use cutting oil as well while drilling to keep the bit cool. Another thing you could try would by using small carbide burrs to slowly chip away at the drill bit until you get most of it out and can keep drilling the bolt.
