Cemented Carbide Tools: Grades, Applications, and Benefits

What are the different grades of carbide tools and how are they classified?

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.

What are the key applications of cemented carbide tools in the manufacturing industry?

Applications of Cemented Carbide Tools

Cemented carbide tools are widely used in the manufacturing industry for various cutting, grinding, and drilling applications. Some key applications include:

Key Applications:

Cutting: Cemented carbide tools are commonly used for cutting operations in industries such as aerospace, automotive, and metalworking. They offer high precision and durability, making them ideal for machining applications that require tight tolerances.

Grinding: In grinding operations, cemented carbide tools are used to produce precision components with smooth surface finishes. They are capable of maintaining sharp cutting edges for extended periods, resulting in efficient material removal.

Drilling: Cemented carbide drills are essential tools for drilling holes in various materials, including metal, wood, and composites. They provide excellent heat resistance and wear resistance, resulting in longer tool life and improved drilling performance.
