Nice set of metric drills
This set is a great value for your money . The storage case is very functional and markings are easy to read. The 5% cobalt content makes them very durable and are very sharp. I have drill metals and plastics so great drill ability. Great buy if you are into 3D2A projects.

arrived as pictured I don't know if these are actually solid 5% someone post in the comments....
Some claim these are not solid cobalt...maybe a coating...I did not really test these out but my intuitive hunch says maybe these are on the cheaper end ... if these don't end up lasting more than 1 use. ( but I don't really know ). Just wondering what the amazon procedure is to test actual claims. 5% this 8% that.

Sharp drill bits.
Bits work great. Mostly used these to drill holes in plastic parts, which is relatively easy. They are definitely sharp out the box and left very clean holes. My only complaint is the box. Mine came with the black holder in pieces. Not sure how it got broken inside of the clear plastic box. I'm not interested in replacing when all it does is store it, just a slight annoyance.

Did not preform to ad specs. However, still a good value for the price.
Ad has will drill Rockwell hardness 67. I was trying to drill the handle end of a knife and it did not work. The highest hardness of the knife steel can be in this case was Rockwell hardness of 62. That means the drill bit should have worked. But it did not. The good news is the tip of the drill bit only got dull, and it did not break. However, the drill bit set it is a good value for the price. Note I could not effectively centerpunch the steel. If you can't center punch the steel that could be a good indication you cannot drill it with this set.

Realy good quality drill bits
I made my mounting rack for my solar panels out of used steal pipe, and I had to drill quite a few holes for mounting these panels. The piping was quite hard and I bought five drill bits, so as to make sure I wouldn't run out. To my surprise the drill bits held up really well and I was able to drill all the holes with just one bit. I did pre-drill the holes with a center drill, but that was all I used, and of course some lubricant. I never thought that I could drill these many holes without wearing out the drill bit. Quite amazing.

Works great
A hardened piece of steel that broke several conventional bits did not stop these drills. Amazing difference from normal drill bits. Use caution; they will snap if driven too hard / fast. Use lubricant and go slow...they work very well.
