Review: Strong cobalt drill bits cut hard metal well - This cobalt drill bit set performs really well on harder materials. The bits stay sharp and cut cleanly when used with proper speed and pressure. Sizes are accurate and the set covers most common needs. Used them for metal drilling and they handled the job without overheating or dulling quickly. Great value set for DIY or shop use and a nice upgrade from standard bits.
Review: I cleared a stripped screw head using one of these bits - I cleared a stripped screw head using one of these bits and it took me less than 20 seconds. I had previously tried using several different extractors and none worked. One of these bits was literally the only way I could remove the screw. For note taking purposes, the screw belonged to a door knob and was also warped. I am happy with the quality of all of the drill bits. Mine came slightly lubricated with some kind of machine oil. The affordability of these cobalt drill bits is excellent and their performance is even better. The speed that I was able to remove the stripped screw with was amazing. I literally drilled into it and the lingering stuck knob literally fell off. If all else fails and you're trying to remove a stripped or warped screw, try using these bits to help you out.

### ⭐⭐⭐⭐ A mostly sharp set, but the little guys are a bit dull (pun intended)
*by K***L on December 2, 2025*

I love a good drill bit set. There is something deeply satisfying about opening a fresh case of organized bits—it makes me feel like I can build a deck, fix the car, or at least hang a picture frame without putting 14 unnecessary holes in the drywall. This set is almost perfect. The Good: The case is sturdy and holds the bits tighter than I hold onto the thermostat setting in the winter. The larger bits are absolute beasts; they chewed through wood and mild steel like it was butter. The "Eh, Needs Work": I knocked off a star because of the smaller gauge bits. I tried to drill a pilot hole into a stainless steel bracket, and the small bit just sort of spun around on the surface like a breakdancer. It didn't "bite" at all. It was less of a "drill" and more of a "friction heater." Summary: Durability: High (for the big ones). Value: Great for the price. Performance: 90% excellent. Just be warned: if you need to do fine detail work on hardened stainless steel, the little bits might give you the silent treatment. Still, a solid addition to the toolbox. I’d tell you a joke about a drill, but it’s boring.
