How should these drills be stored?
PCB drills less than 0.5mm are easily damaged because they are small and thin. It is recommended to be careful when using.
The hardness of the bit is very high and the toughness is low. Please do not fall to the ground, it is very fragile and may break.
What do you need to pay attention to when using it?
When using, you must apply force evenly and vertically. Do not touch the blade with hands or external force to avoid damage.
This kind of tungsten steel drill is mainly suitable for high-precision professional drilling equipment, such as PCB drill.
What materials are these drill bits suitable for?
0.01-0.05 inch drill bit set for precision drilling of amber beeswax, circuit boards, CNC engraved jewelry, hardware, plastics, etc.
- 30 pieces of drill bits in the package, divided into 3 groups, 10 pieces in each group
- Made of quality tungsten steel, not easy to wear and bend
- The anti-vibration design of the blade makes it stable and reliable during the engraving process
- High machining accuracy, no burrs or debris

Obviously for the tiny amount of material to make such precision modifications they are inherently delicate. But if you are tactful with your implementation, they are great. The bits are rather sharp. Aunt certainly sufficient for wood, plastic and softer metal. I use them enlarge some of the nozzles on the tip of GDI fuel injectors. I did break a couple bits figuring it out, but once I had everything stable it was smooth sailing

Got these, went to drill a circuit board and within a second, the drill bit snapped. These are junk.

Would give it 5 stars except for the poor instructions. Even sent email to maker but never responded.Eventually figured out how to get it working and after that it was great.

If you need some micro bits for cheap, look no further. Two packs for such a low price is a steal. I've only used one size so far but have had zero issues which is to say the quality and durability seem pretty good.

I use them to drill through pearls, and they do great.

I had to return it because the shank on the drill bits was too large to be used on the Arrowmax drill pen that I purchased. The quality and packaging looked good, but I was unable to use the bits

They are too thin, unnecessary and weak but if you still want to try them, I would say go for it because everyone's needs and uses are different.
Amazing Calipers!!
