Cemented Carbide Tools: Grades, Applications, and Benefits
The Grades of Carbide Tools
Carbide tools come in a variety of grades, which are classified based on their wear resistance and toughness. The grades of carbide tools commonly used are Nano, Ultrafine, and Submicron.
Classification of Carbide Tool Grades
Carbide tool grades are classified based on their particle size and binder content. Nano, Ultrafine, and Submicron grades are popular choices for end mills due to their high hardness, compressive strengths, wear resistance, and reliability against breakage.
Nano Grade: This grade of carbide tools has particle sizes below 1μm, making them extremely hard and wear-resistant. They typically have a binder content in the range of 3-12% by weight, which contributes to their high compressive strengths.
Ultrafine Grade: Carbide tools in the Ultrafine grade category have slightly larger particle sizes compared to Nano grade, but still fall within the submicron range. They offer a good balance of hardness and toughness, making them suitable for a wide range of applications.
Submicron Grade: The Submicron grade of carbide tools has particle sizes slightly larger than Nano and Ultrafine grades, but still smaller than conventional carbide tools. They provide high wear resistance and toughness, making them ideal for demanding machining operations.
