Tungsten Carbide Cermet Cutting Tools

Compared to cemented carbide, cermet has improved wear resistance and reduced smearing tendencies. On the other hand, it also has lower compressive strength and inferior thermal shock resistance. Cermets can also be PVD coated for improved wear resistance

Tungsten carbide hard materials offer several advantages when used in the formulation of cermet composites. 

1. Superior Surface Finish: Tungsten carbide’s hardness contributes to a smoother cutting action, reducing smearing tendencies. This results in a superior surface finish on the machined workpiece, which is particularly beneficial in high-precision applications.

2. Thermal Stability: Tungsten carbide has excellent thermal conductivity and stability, which helps in dissipating heat generated during high-speed cutting operations. This reduces the risk of thermal damage to both the tool and the workpiece.

3. Versatility in Coating: Cermet tools can be PVD (Physical Vapor Deposition) coated with tungsten carbide to further enhance their wear resistance and performance. This coating provides an additional layer of protection, making the tools suitable for more demanding applications.

4. Application Flexibility: The combination of tungsten carbide and ceramic materials in cermet allows for a balanced set of properties, making these tools suitable for a wide range of applications, including automotive, aerospace, and general manufacturing industries.

5. High-Speed Cutting: The hardness and thermal stability of tungsten carbide make cermet tools ideal for high-speed cutting operations, where maintaining tool integrity and performance is critical.
