Efficient Universal Drilling Tools, Cemented Carbide Drill Bit Set, 8Mm High Hardness Drill

Overview This professional glass and tile drill bit set is designed for users who need smooth, precise drilling in hard materials such as ceramic tile, marble, thin iron plates, mirrors, and glass. Made from high-quality YG6X alloy and featuring a unique cross-angle design, these drill bits ensure stable, fast drilling with clean edges and minimal resistance. Product Details Crafted from premium YG6X alloy, the drill bits undergo an oxynitriding treatment on the cutting head for enhanced hardness. The electrophoretic surface painting process provides a complete anti-rust treatment, resulting in a clean, sharp finish without burrs. Fully automated polishing ensures each bit is uniformly refined for increased wear resistance and durability. The unique cross-angle design reduces cutting resistance, enabling stable, high-speed drilling without border breakage. Neat, smooth openings are achieved with no shaking or flaking. For optimal performance, remember to use water or liquid cooling during drilling. Key Features 1.
