I had to replace some parts on the front clip of my daughter's car (someone backed into the car when it was parked) and drilling out a broken rusty bolt was required.
My existing drill bits (most of them good quality HSS) were a no-go for this task so I picked up a set of the DeWalt Cobalt drill bits:

These worked REALLY well for that job, and the centering feature was quite helpful, but I did notice two drawbacks with additional use:
1. If you drill a smaller "pilot hole" and try to go up gradually in size to enlarge the hole, the lack of a stand point angle on the flutes for centering is a problem.
2. Because of the unique point geometry, they can't be effectively sharpened by any means I have available, and I have a "Drill Doctor" sharpening tool as well as a standard-type bench grinder.
Despite these drawbacks, I very highly recommend these for anyone needing to drill into or through hard metals.
And remember: Cutting oil is your friend.
