do drill bits have etched "HSS Co"? or else how do you know they are Cobalt drill bits?

3mm-13mm have HSS*Co logo and size marking 1mm-2.5mm is too small to be marked, but also contains cobalt

what tolerances can I expect?

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

what is the cutting tip angle?

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.
