Overall, others give this:
I had to drlll out some old rusty bolts on an exhaust system and my regular bits couldn't do a thing. I bought the cobalt drill bit and it ate through the bolt like nothing - problem solved!

I found the bit perfect for the job that I had intended. It stayed in place and didn't vibrate at all. I wish they had other sizes in Cobalt, maybe even a "kit". I like this because It got the job done.
Craftsman cobalt drill bits are fantastic for drilling into steel and hard metal. These drill through even thick plate if you take your time or use some cutting fluid. They are more brittle than regular drill bits so you have to use care, but if you treat them right they will get the job done every time.
