Had to get some very stubborn exhaust flange bolts out, started by cutting with angle grinder then drilling. Ruined several bits before I realized I needed carbide bits. Ruined 2 of those while drilling out 4 bolts, and remaining parts of bolts still wouldn't come out. Got these burrs to finish the job with a die grinder from the super cheap box store (you know you shop there too!). These grinding burrs held up surprisingly well. Had to push all the way through the flange with a tapered burr, and was pushing hard, got serious vibration several times because of sloppy technique, but burr held up, no sign of wear on grinding surface all, bolts finally out and holes cleaned. These work, and hold up.

I used this to grind out a broken drill bit that broke off in a stud that had broken. After many attempts to drill out with cobalt bits I chucked it up in a die grinder and it went right through to my amazement. Definitely need in your arsenal for removing studs and broken bolts.
