I've got some cobalt drill bits for tough jobs, so I'm going to dry to only use these for wood and softer metals.
Just drilling out a screw can be more than a cheap set of drill bits are up to. If it was anything more than a drywall screw, it was likely hardened and I wouldn't touch it with anything other than a high quality cobalt drill bit. These are cheap titanium nitride coated bits best served in plastic, wood, and soft easy drilling metals. Hardened steels will almost certainly lead to rapid destruction.
Also drilling on any metal without cutting fluid is a great way to damage bits. I like this as a budget option rather than paying for small jars of expensive lubricants or using a poor lubricant like WD-40 (which is a solvent and lubricant before some parrot says it's a solvent).
