Comments about Advantek Workshop Titanium Drill Bits 21-Pc. Set:
I bought these bits to use at work (i'm a mechanic) and the first time I used a bit to drill out a rivet, it dulled halfway through the rivet. I tried the next size up and it dulled too. I borrowed a buddies snap-on drill bit and it ate up the rivet. (I avoid snap-on because of price, but snap-on drill bits are some of the best I've used.) I would save these bits for soft metals such as aluminum or use them for dilling in wood.
