New Product: Nano Blue 2.5*D4*50*60° High-hardness Centering Drill, Double-edge Chamfering Cutter, Tungsten Steel
This 2-flute centering spot drill is crafted from premium solid tungsten carbide with new high-hardness nano blue coating. With 2.5mm cutting diameter, D4 shank, 50mm overall length and 60° point angle, it integrates centering, spotting and chamfering functions, fully compatible with 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 wear resistance and thermal stability, maintaining sharp cutting edges and significantly extending tool life when machining hardened materials.
It is ideally suited for spotting, chamfering and deburring on hardened steel, die steel and other high-hardness workpieces. As a cost-effective alternative to imported equivalents, it reduces tooling costs while delivering consistent machining quality for high-volume batch production.
