Review on 20 Pcs Micro HSS Twist Drill Bits 0.5Mm-3Mm With Aluminum Hand Drill Model Craft DIY Tool by Chase Cooper

As many have stated. the case SUCKS. hard to open, hard to slid, hard to use. just a bad production of a generally good idea. The tool broke the second time I used it and a couple of bits were more tiny rod than drill bit. Upon inspection with a magnifying glass, some of the flutes were incomplete or not existent. You do get a couple of each size so I was able to use this kit for the intended purpose and definitely see the benefit of having one. Which is why I bought another kit of much higher quality for a little bit more money. If you have a notion to buy a set of tiny bits, I recommend buying a higher quality.
