1. Ultra-fine-grained cermet matrix: Cermets are composed of a ceramic matrix (TiCN) and metals (CO, Mo). Nano-scale material composite technology provides the insert with increased hardness and impact resistance, reducing the risk of chipping.

2. Multi-layer composite coating: Utilizing a PVD/DLC coating process, very thin coatings (<1μm), such as DLC coating, enhance wear resistance during high-speed cutting and extend tool life.

3. Optimized cutting geometry: The unique process structure applies a passivation treatment to the sharp cutting edge, creating a geometrically designed cutting edge that suppresses vibration and ensures a surface finish of Ra 0.5μm.

4. Upgraded chipbreaker structure: Precisely controls chip flow, preventing cutting entanglement and improving continuous machining stability.
