I was trying to remove two tiny hex screws that mounted a rear sight onto a pistol slide so that I could Cerakote the pistol.
Not as well as I planned. I did not have the required 0.7mm hex wrench or bit and nobody locally or semi-locally sold anything that small. So I went to a computer repair shop and borrowed their 0.7mm bit to try and remove the two hex screws. Because the bit was so tiny, it immediately broke. Since nobody sells just that one bit, I had to purchase the whole kit online to replace the bit that I broke. The computer shop got their kit from Ifixit, so I ordered the exact same thing they had. Instead of attempting to remove the screws again (and risk breaking another bit and having to re-order another kit), I sheared the screws off and ordered replacement screws from the manufacturer instead.
Please make the micro bits out of stronger material, such as titanium. I would gladly pay more money for a stronger bit that would be able to withstand the torque required for gunsmithing projects.
