Description
These high-quality micro PCB drill bits are designed for creating precise tiny holes needed in PCBs. Made from durable tungsten steel, they offer high hardness and excellent wear resistance, ensuring they do not bend or break easily. The sharp cutting edges reduce cutting force, improve drilling quality, and provide smooth, efficient drilling with minimal resistance. Strictly symmetrical cutting edges ensure accuracy and prevent deviation. Ideal for PCB, SMT, mold, hardware processing, and electronics applications, these drill bits come in sizes 0.35mm, 0.6mm, 1.0mm, 2.4mm, 2.6mm, and 3.1mm.
