belt grinders are the best if you are scrapping the panel. WAY faster than drilling out spot welds.
they are really great when sanding down the weld nugget. i like them better than using a grinding disc to do that.
they really shine when you have to remove a ultra high strength steel panel. regular cobalt bits won't even put a tiny divot before going dull. they do make special bits for this. they are $$$$ though. sanding belts are cheaper.
