(SJ01)1pc 1/4″3-12mm Hex Shank Twist Glass Bit Titanium Ceramic Drilling Drill


The titanium ceramic drilling drill features a solid carbide or high-speed steel body with a titanium nitride (TiN) or titanium carbonitride (TiCN) coating. The titanium coating enhances the hardness and wear resistance of the drill bit, allowing it to withstand the high temperatures and friction generated during drilling.
