■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.
■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.
■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.
■Amine paper has good chip removal and can keep the board surface clean and dust-free.
