The teeth feel much catchier after filing them with a triangular jeweler's saw (left half is done), but it still takes a minute of rocking the but back and forth to get through 3/4" plywood.

Honestly I just assume grab new ones once they go shitty, the cost of me taking the time to mess with it vs buying a new one is not worth it in terms of productivity. In my world of electrical the holes need to be perfectly circular, so I just assume not waste time on it.
Right there with you. I have cheap sets in case I loose the carbide-tipped ones in the size I want between pay-checks, and to lend out, but if one of those cheapos goes egg-shaped, I'm more likedy to throw it away or find another use for it than to try to fix it.
