Re: Killer Drill Bit?
The cobalt bits I have aren't cutting. I need a clean drilled hole, not eat the bolt up. This isn't a ceased bolt, just a broken bolt. Not rusted in. It should back right out once I get a grip on it. I figure a LH bit will turn it out. If not an extractor into the drilled hole.
I know about building up a weld in a hole using copper tube to line the hole. But I don't have a wire feed welder and this is a starter bolt hole in a 350 in the truck. Pretty tricky welding above on what you can only see from below. It would be nice with engine out and on a stand flipped upside down. I'm trying what I can with engine in truck
