Nice quality small bit set.
Only reason I didn't give it five stars for durability or longevity is that I haven't had it long, and have used it only once. Given how it performed when I used it, though, I don't anticipate anything but more of the same; nice 'bite' into the aluminum plate, clean hole walls, even swarf curls from each gullet, so the flukes are cutting evenly, which means the tip is ground accurately and not cutting one-sided. These will be seeing frequent use!

Works on hardened bolts
I needed to drill out a broken-off 12mm hardened bolt in close quarters on my Honda Odyssey, and bought these hoping they were really hard cobalt steel and would not wander excessively without a center punch. These were exactly what I needed; I was able to center the drill and keep it there in the center of the bolt despite the awkward position, while the drill worked its way into the hardened M10.x bolt that I was so worried about. That one use alone made this purchase worthwhile, and now I have a whole set of these to use when I need something more than the junk drill bits sold at our local home supply store.

Good quality bit set
The drill bits are good quality for the price the case however is junk and was broken on arrival. I have been using these bits quite regularly for a few months now, and they seem to be holding up well. Most of what I've been drilling is PCB boards and plastic with a small amount of thin metal.

Sharp bits
Arrived quickly and are very sharp, work well in a pin vise for 3D prints and minis.

Re-label of a sae set
Amazing how the strange metric sizes like 4.8 are the exact same as a standard sae set.

works great, sharp point makes a hole when you spin it
I needed metric bits, these were the best price on amazon of the time regardless of the material composition. I typically don't buy cobolt bits because I can't sharpen them, but these are mostly used in 3d prints, brass, and aluminum so I am not worried about them getting dull (I hope).I am very pleased to finally have a full metric set.
