Expanding tap. You grease the shit out of it, put it in, expand it into the existing threads then back the whole thing out of the hole. It cuts (more like un-distorts) the messed up threads on the way out and any chips come back out with the tap. I'm not endorsing that particular brand or model, it's just for reference. Make sure you do a really good job of getting it seated in good threads or you'll be doing a heli-coil.
