BB Countersink Drill Tipped Carbide 90 Degree TiZr涂层 reducing processing stepsBB Brazing Countersink Cutter In order to ensure the firmness of the drill bit, we adopted a brazing method to weld carbide inserts. In this way, the drill bit can process harder metal (compared with HSS countersinks). But this will make the appearance of the drill bit not good looking. We hope you don't mind. Because the cutting edge of carbide material is very crisp, them machining environment needs to be stable to reduce beating. It performs well
