New Product: Nano Blue 6*50*60° High-hardness Centering Drill, Double-edge Chamfering Cutter, Tungsten Steel
This 2-flute centering spot drill is built with premium solid tungsten carbide substrate and upgraded high-hardness nano blue coating. With 6mm cutting diameter, 50mm overall length and 60° point angle, it integrates centering, spotting and chamfering functions, fully compatible with all standard CNC machining centers.
The double-flute structure delivers precise centering accuracy and stable cutting performance with minimal vibration. The high-hardness nano blue coating provides exceptional abrasion resistance and thermal stability, maintaining sharp cutting edges and significantly extending tool service life when machining high-hardness materials.
It is ideally suited for spotting, chamfering and deburring on hardened steel, die steel and other hard workpieces. As a cost-effective alternative to premium imported equivalents, it reduces tooling costs while delivering consistent machining quality for high-volume batch production.
