Drill, baby, drill
I've only used a few of the small ones so far, but they have been great. Nice and sharp, and I haven't broken any yet.

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.

Great Drills, Poor packaging.
The drills themselves are excellent quality. However, the cheap plastic enclosure with 3d printed connectors were damaged upon receipt. Not a show stopper, as I'll probably #D print a different storage solution anyway.

Did the job
These drill bits drilled out the bolt with no problem at all. This was a great value.

Does the job at a fair price
A lot of 3d printing files call for metric-sized holes, so I bought some metric-sized bits. They work great. Haven't really tried them on wood or metal, but plastic is isn't much of a challenge for any bit. Nothing bad to say though, and the drill index / box is pretty nice.

Decent drill bits in a flimsy plastic case
Drill bits are good but the carry case is crap. I would have returned this but I needed to complete my project so I am dealing with the flimsy busted carry case.
