... twice a week
Good bits last for years. Ten times the upfront cost once vs a new set over and over plus all the cursing and grumbling
I hope you are right. I'm going to give them a try. The reviews with snapped drill bits don't scare me. Any small drill bit is prone to breaking, and the harder ones are even more brittle. What does concern me is the images where the drill bit debonded from the shank. Hope I don't have that happen.
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.
I'm heeding some caution based on what you are saying, but also realizing you may have been using them pretty hard.
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).

They click into impact drivers very well but they don't hold up well drilling metals. Don't apply too much pressure or they can snap at the shank.
For Wood drilling and anchoring pilots this set is great.

Good info thank you. I have 3-in-1 oil that works well. I did break one of these on a screen door frame screw and it was just too much pressure needed to punch through it, probably. Either way I will look into a few Cobalt bad boys for the tough jobs
