Applications: Ideal for high-intensity cutting, drilling, brazing, and electroplating tools. Used in reinforced concrete, hard granite (F=15), high-hardness ceramics, and engineering drill bits. |
HSD70 | Features: Hexoctahedral crystal structure, few impurities, high static strength, impact toughness (TI), and thermal stability (TTI). Good wear resistance.
Applications: Suitable for cutting, drilling, brazing, and electroplating tools under high-intensity conditions. Used in concrete, hard granite (F=10), high-grade tiles, refractory materials, heavy-duty grinding, and medium-to-high-load electroplating tools. |
HSD60 | Features: Hexoctahedral structure, few impurities, moderate strength, TI, TTI. Balanced wear resistance and sharpness.
Applications: Ideal for high-speed cutting/drilling under medium intensity. Used in cement pavement, marble, granite (F=8), building materials, refractories, non-ferrous metals, heavy grinding, and medium-load electroplating tools. |
HSD50 | Features: Regular hexoctahedral structure, moderate impurities, average strength/TI/TTI, moderate wear resistance, good sharpness.
Applications: For high-speed cutting/drilling under low-to-medium intensity. Used in soft marble/sandstone (F=6-5), glass, ceramics, building materials, medium-load grinding, and low-to-medium electroplating tools. |
HSD40 | Features: 90–95% regular structure, moderate impurities, low strength/TI/TTI, average wear resistance, excellent sharpness.
Applications: For high-speed cutting/drilling under low intensity. Used in small-diameter free-cutting drills, medium-to-low load grinding, and low-load electroplating tools. |
HSD30 | Features: 85% regular structure, more impurities vs JSD40, low strength/TI/TTI, poor wear resistance, excellent sharpness.
Applications: For small-diameter free-cutting/drilling tools. Ideal for high-brittle materials like gemstones, jade, crystal, and small batches of stone/glass/tiles. Also for medium-to-low load grinding and low-load electroplating tools. |
HSD20 | Features: 70% regular structure, high impurities, rough surface, low strength/TI/TTI, poor wear resistance, extremely high sharpness.
Applications: For small free-cutting/drilling tools, ceramic/metal bond tools, and sharp electroplating tools. Used on hard alloys, magnetic materials, glass, tiles, crystal, gemstones, and other brittle materials. Can be blended with high-grade diamonds to adjust tool sharpness. |
HSD10 | Features: 50% regular structure, high impurities, rough surface, very low strength/TI/TTI, very poor wear resistance, extremely high sharpness, good self-sharpening.
Applications: For resin/ceramic/metal bond tools and sharp electroplating tools. Used on hard alloys, magnetic materials, glass, tiles, crystal, gemstones, and other brittle materials. Can blend with high-grade diamonds to adjust sharpness. |
