I bought these to get a broken exhaust bolt out of the engine. I also broke the extractor on the bolt. I had a goal for her to get that bolt out. They worked! Variable speed Dremel tool, patience and that little set of carbide cutters slowly and carefully not to hit the aluminum where the screw broke. Yes, it took time, but they grind hard metal. After work I tried a piece of wood, then fiberglass, no problem. They didn't dull or break. Good tools.
