Review on WayinTop Carbide 0 3Mm 1 2Mm Circuit Engraving by Joseph Hall

Too many negative reviews, breakage, misalignment etc. These drill bits are perfect for me. I build plastic models of airplanes for accuracy and authenticity, and many models require small holes of 0.4-0.6mm to mount weapons. Until I tried them, I always had one size smaller or larger. Now I can easily drill these small holes. As a bonus, the interiors on some ships look more authentic when the sculpted, simulated openings in the structure are also revealed. It's easy to do now. I don't use tools like a Dremel or a small drill, I just twist my fingers. There are no defective parts yet and are not expected. But at this price point and with 5x the number of drill bits, I think a few broken drill bits would be acceptable. I looked closely at the accuracy as there is a slight eccentricity of some drills to the shank, not much but still.
