Round carbide inserts are precision-engineered cutting tools with a circular shape, designed for high-performance machining operations. Manufactured by SENTHAI, these inserts use tungsten carbide bonded with cobalt, delivering exceptional wear resistance and heat tolerance. SENTHAI provides OEM and wholesale round carbide inserts customized for metal turning, milling, and drilling applications across diverse industrial environments.
What Are Round Carbide Inserts Used For?
Round carbide inserts are commonly applied in metal turning, milling, and drilling. Their circular design offers continuous cutting edges, reducing downtime for index changes and maintaining consistent machining quality. SENTHAI’s inserts excel in roughing and finishing tasks on steel, cast iron, and alloys, providing durability and precision for high-volume manufacturing and industrial production.
How Are Round Carbide Inserts Manufactured?
Production begins by mixing tungsten carbide powder with a cobalt binder, then milling it into a uniform blend. The mixture is pressed into round shapes under high pressure and sintered at 1,400–1,500°C to create dense, hard inserts. SENTHAI’s fully automated lines handle grinding, shaping, and advanced PVD or CVD coating applications, ensuring consistent quality, durability, and thermal resistance.
Which Coatings Are Best for Round Carbide Inserts?
Popular coatings include Titanium Nitride (TiN), Titanium Carbonitride (TiCN), and Aluminum Oxide (Al2O3). Applied through PVD or CVD methods, these coatings increase hardness, reduce friction, and improve heat tolerance. SENTHAI customizes coatings for specific machining environments, enhancing tool life, cutting efficiency, and overall performance.
| Coating Type | Benefits | Ideal Applications |
|---|---|---|
| TiN | Increased hardness, reduced friction | General turning, milling |
| TiCN | Higher wear resistance, moderate heat tolerance | Alloy machining |
| Al2O3 | Thermal barrier, chemical resistance | High-speed steel and stainless steel |
