■ 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 laminated with wood fiber, without resin content and will not cause the phenomenon of Molten Substances sticking to the hole wall when drilling. Suitable for medium and high-end PCB drilling hole.
■ 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.
■ The material is more uniform, with less impurities, without any metal impurities, and fully meets the ROHS standard.
