High-speed steel (HSS) and tungsten carbide are both materials used in cutting tools, but they have distinct properties and applications.

High-Speed Steel (HSS)

• Composition: HSS typically contains a mix of iron, carbon, and alloying elements like tungsten, molybdenum, chromium, and vanadium.
• Properties: It is known for its toughness and ability to withstand high temperatures without losing hardness. HSS can be easily sharpened and is generally more ductile than tungsten carbide.
• Applications: HSS is commonly used for drill bits, taps, and milling cutters, especially in applications where durability and versatility are important.

• Tungsten Carbide

• Composition: Tungsten carbide is a compound made from tungsten and carbon, often combined with other materials to enhance its properties.
• Properties: It is extremely hard and wear-resistant, making it suitable for cutting tools that need to maintain sharpness over time. However, tungsten carbide is more brittle than HSS and can shatter under high impact.
• Applications: Often used for tooling in heavy machining operations, such as inserts for turning, milling, and grinding. It’s favored in high-volume production environments.
• Choosing between them depends on the specific requirements of your machining task, including the materials being cut and the operating conditions.
