NX2525 Cermet Technology and L-2G Finishing Chipbreaker

The NX2525 Cermet grade combines the toughness of cemented carbide with the hardness and high-temperature oxidation resistance of ceramics. Being uncoated, the cutting edge remains exceptionally sharp and free of internal stress, which eliminates the formation of a built-up edge (BUE) when machining ductile steels and case-hardening steels. The left-hand L-2G chipbreaker guides the chip smoothly during medium and fine turning operations, preventing scratches or damage to the machined surface.
