Review: Excellent for scale models!! These micro drill bits will work in any adjustable chuck hand drill. As some of the bits are oh so easy to break, at this price point it’s worth having extras on hand.
Review: ５ケース入りだったので購入。当たり前だが，細いドリルは作業中に余計な方向から力が加わったり，落としたりするとすぐに折れる。使ってすぐに折れた。慣れてくるとそれほどでもないが，慎重さは必要。特に０．４ｍｍ以下は折れに注意。それ以上の大きさはずっと使えそうな感じがする。５セットもあるので。

## Questions & Answers

**Q: What is the diameter of the shaft?  Will it fit in a standard pin vise?**
A: Diameter of the shaft is 1/8" or .125

**Q: Can I put these in a dremel tool?**
A: Absolutely, but you have to remember these are extremely brittle.  ANY side force will break the bit.  You are best served using them in some sort of press but with very steady hands and a thoughtful method, operating by hand is possible.

**Q: can these be use by hand twisting on brass jets in carburetors to enlarge the one increiment at a time?**
A: I'm going to say yes. I twist them by hand, but I should also mention that I'm drilling into wood. I build model ships. Drilling into brass might be possible, but be aware that these bits, although very effective drilling into wood, are very brittle. I can't tell you how many have snapped on me when I least suspect it and I have to break out another set. I've learned to drill carefully and with patience.
Other than that, I do like these bits and have started using them in my Dremel.

**Q: Are these recommended for drilling into raw semi-precious stones (like Crystal Quartz, amethyst, agate etc) for the purpose of creating pendant holes?**
A: No. You really need a diamond bit or hole saw, depending on the size. You'll also want to have a water drip going or at least use some sort of lubricant such as beeswax or gem lube.

They do the job but as to be expected, the small (er) ones are super easy to break so yeah, the 5 pack is gonna come in REAL handy. It's not the tools fault it's the tool running the tool, I didn't have my drill bit square to the piece i was drilling a couple of times and they break easy. If you're using them square to you work piece and dont change the bits angle once you're in and allow the bit to pull itself through you will be amazing at what they can do
