Review: The drill sizes are not marked on the drills - My immediate reaction was the drill bits looked well made and the individual boxes will provide good protection for the drill bits. I wasn't thrilled that the bits are not marked with the size. It was not difficult to make labels to affix to each bit and I have already done so. Doing it took some time but at least I won't have to measure a bit every time I want to use them. I used a digital micrometer to measure each bit. As far as their performance goes they work great. They are very sharp and I have already used them on three types of wood and bamboo, as well as plastic. The bits cut through everything with ease. I even had to drill some holes on sloped surfaces and if you start slowly the bits will not deflect. I think because they are tungsten carbide they are quite stiff and that helps on angled surfaces. However, I am sure most users know that since they are stiff and being quite small diameters you will have best results if used with a drill press. Drilling by hand can be done but the risks of breaking bits is greater Overall I am very pleased and hopefully the bits will stay sharp over time.
Review: sharp - They look like nice bits they seem to work well, I have broken 2 of them but I think that is more due to my lack of knowledge in how to operate my cnc machine. I m trying to etch a circuit board for an automation system I built, but what I did was prove that I am not even smart enough to open a box of cnc bits without injuring myself. I tried to open one of the boxes and it was stuck kind of hard, so I forced it open and buried the .4 and .5 bits into my finger, all the way in. I wish I had the cognitive reasoning of a sane person that didn't have two long needles stuck in their fingers and had taken a picture, because it looked like uncle martins antenna from my favorite Martian sticking out of my finger. To make matters worse I kept hearing this high pitched squeal and immediately though ,oh no, I must have accidentally turned on the machine. So instead of pulling out those 2 tiny daggers that thankfully my distal phalange (top finger bone) had to forethought to stop for me, I started looking at the machine to make sure it was off. The noise as it was, happened to be my daughter (20) squealing like a nutter because I was standing there with bits of tools sticking out of my person at odd angles. Worst of all it was my middle finger, the hardest working finger in the universe. I've been married for 23 years, its how we say good morning, its how we pass each other in the hallway so we can at least say we had hallway sex, its how I let my kids my dog and my boss know that they are number one in my life. They were stuck in so good that they even came out of the box still in my finger. So they are sharp, and be careful opening the little boxes.

## 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.

### ⭐⭐⭐⭐ Good Enough
*by C***S on April 30, 2022*

This set gives you five each of ten different size PCB drill bits for a total of 50 pieces. They have a 1/8" diameter shank and intended to be used with a low torque drill, either manual or motor (e.g., Dremel). These bits are small diameter and will not tolerate bending stresses or high compressive loads without failing. Used with care, they should last sufficiently long to complete a basic PCB project. Don't expect miracles and you will get value for your money.
