how do I open the case, grrr!?

Hello There is a black disposable component in the upper left corner that can be used after destructively removed 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

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.

Hält nicht was es verspricht

Bereits beim ersten Einsatz hat es einen der dünneren Bohrer zerlegt. Die Spitze steckt im Werkstück, ein Teil im Futter der Maschine und der Rest ist weggeflogen. Richtig Vortrieb im Metall gab es auch nicht wirklich (ich wollte eine abgerissene Schraube ausbohren). Und was die 'automatischen Positionierung' sein soll, kann ich nicht nachvollziehen.

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.
