Product Description

A. There is a certain surface hardness to ensure that the drill has a good chip removal ability, so as to reduce the drilling burrs; Meantime it will not be too hard to wear the drill.
        B. The material is composite material with high surface hardness, uniform and smooth surface, and is suitable for high-end precision FPC and PCB small hole drilling.
        C. It has a certain thermal conductivity function, which takes away part of the heat generated during drilling, reduces the temperature of the drill bit, and prevents the drill bit from annealing.
        D. Amine paper has good chip removal and can keep the board surface clean and dust-free.
