Actually the materials that I drill the Lowe's bits fail everytime. The replacement bits I got from Fastenal are still going fairly well after 5 yrs. Of course a few have been re-sharpen as they wear but usually after a few dozen holes unlike the first bits that wouldn't even make it through the first hole without dulling.
Currently the only drill bits I buy are the ones that don't have like the set of left hand bit I looking at for screw extraction but I may just get them with regular extractors from McMasters-Carr.
The truest measure of society is the how it treats its elderly, its pets, and its prisoners.
