If that fiberglass dulls a saw so fast, what about the drill bit used for the holes?
A "Drill Doctor"? Or do you grind holes with a grinding ball bit?
(I know it does dull cutters fast, and saws are hard to sharpen. I'm mostly just curious what your solution is to dull bits. Sharpen or toss um? (Jobber bits are cheap enough, but they aren't even close to my fav.s., even compared to a regrind they often seem too soft for me)
