Yes, carbide is generally tougher and harder than HSS (High-Speed Steel), making it better suited for certain machining applications. Here's a comparison of both materials:
Carbide (Solid Carbide)
- Hardness: Carbide is much harder, often reaching HRC 70 or higher.
- Toughness: Although carbide is harder, it is brittler than HSS, meaning it can break or chip under sudden impacts or if not handled carefully.
- Wear Resistance: Carbide has superior wear resistance, allowing it to maintain its sharpness longer, especially in high-speed cutting applications.
- Applications: Ideal for machining harder materials like steel, titanium, and high-temperature alloys, as well as for precision cuts.
HSS (High-Speed Steel)
- Hardness: HSS is softer, typically around HRC 60, but can still handle higher temperatures than carbon steel.
- Toughness: HSS is more tough and resistant to chipping or breaking under heavy loads compared to carbide. It's less prone to fracturing under impact.
- Wear Resistance: HSS wears more quickly than carbide, requiring frequent sharpening in heavy-duty cutting tasks.
- Applications: HSS is commonly used for general machining, drill bits, and taps, and it's more suited to lower-speed cutting tasks or materials that are not as hard.
