The Cemented carbide tools and saw blades play a crucial role in modern manufacturing. Due to their excellent wear resistance, hardness, and thermal stability, cemented carbide materials are widely used in cutting, drilling, and milling processes. This article explores the characteristics, manufacturing processes, application areas, and future development trends of cemented carbide tools and saw blades.

 I. Cemented Carbide Tools

1.1 Characteristics of Cemented Carbide Materials

The Cemented carbide (also known as tungsten carbide) mainly consists of tungsten carbide (WC) and cobalt (Co) as a metal binder. Its characteristics include:
- High Hardness: The hardness of cemented carbide usually exceeds HRA89, second only to diamond.
- High Wear Resistance: Due to the hard particles of tungsten carbide, cemented carbide has excellent wear resistance.
- Good Thermal Stability: Cemented carbide maintains high hardness and strength at high temperatures, making it suitable for high-speed cutting.

1.2 Manufacturing Process of Cemented Carbide Tools

The manufacturing of cemented carbide tools mainly includes the following steps:
- Powder Metallurgy: Tungsten carbide and metal binders are mixed, pressed into shape, and then sintered at high temperatures.
- Tool Design and Processing: The geometry of the tool is designed according to specific applications and precision machining, such as grinding and coating, is carried out.
- Coating Treatment: A wear-resistant coating (such as TiN, TiAlN) is applied to the tool surface to further enhance its performance.

 1.3 Applications of Cemented Carbide Tools

Carbide insert are widely used in the following areas:
- Metal Processing: High-precision metal cutting such as turning, milling, and drilling.
- Woodworking: Suitable for cutting hard wood and composite materials.
