Review: Great for 3d printing - Bought these when i got back into 3d printing and needed to be able to precisely clearance holes in things i had printed since 99% of measurements used in 3d printing projects are metric. Well made, works well, great price, and the plastic case locks closed so you dont have to worry about them bouncing around in a bag and falling out.
Review: Great bits - very sharp! - I'm super-happy with these bits. They are very high quality and very sharp.

## Questions & Answers

**Q: how do I open the case, grrr!?**
A: Hello

We are sorry that our products have caused you an unpleasant experience
We will document this issue and will improve it
Have a great life

**Q: do drill bits have etched "HSS Co"? or else how do you know they are Cobalt drill bits?**
A: 3mm-13mm have HSS*Co logo and size marking
1mm-2.5mm is too small to be marked, but also contains cobalt

**Q: what tolerances can I expect?**
A: From the product manufacturing technology:
   The diameters are all standard sizes
   Drill length and cutting edge length may have small measurement errors with the solid
From the perspective of use:
   Borehole diameter, face tolerances range from 0.01mm to 0.5mm, and the tolerance slowly decreases as the depth increases 
   Cordless drill with maximum tolerance for handheld operation 
   Table drill tolerances will remain below 0.1mm
Hope this helps with your question

**Q: what is the cutting tip angle?**
A: Tip angle 118 °
This is the best angle for the cobalt twist drill. The tip angle of all sizes of the set is 118 °. The new product can be used out of the box without trimming and grinding.
