Coarse Synthetic Diamond JSD Series

JCB JSD series of synthetic single crystal diamond coarse grains refer to diamonds with a grain size ranging from 20/25 to 50/60. These products are characterized by their golden-yellow crystal structure, complete crystal formation in a six-eight octahedral structure, low impurity content, good transparency, and outstanding static strength, impact toughness, and thermal stability. JCB JSD series of diamonds are primarily used in the manufacturing of diamond saw blades, diamond wire saws, thin-wall diamond drills, diamond grinding blocks, diamond wheels, geological drilling tools, and brazing tools, among others. They find wide applications in industries such as stone processing, cutting of reinforced concrete, construction of roads and bridges, glass processing, oil and gas drilling, and mechanical machining.

	JSD90 Features: The crystal form is complete and regular hexahedron, with almost no impurities in the crystal, extremely high static strength (Newtons), impact toughness (TI), and thermal stability (TTI). The comprehensive performance reaches the level of international equivalent products, with excellent wear resistance. Applications: Suitable for cutting tools, drilling tools, and brazing tools under extremely high working strength conditions; such as cutting and drilling high-strength reinforced concrete, asphalt pavement, and extremely hard granite (F=20), as well as high-performance geological engineering drill bits.
	JSD80 Features: The crystal form is complete and regular hexahedron, with very few impurities inside the crystal, and has very high static strength (Newtons), impact toughness (TI), and thermal stability (TTI), with good wear resistance. Applications: Suitable for cutting tools, drilling tools, brazing tools, and electroplating tools under high working strength conditions; such as cutting and drilling reinforced concrete, high-hardness granite (F=15), and high-hardness ceramic materials, as well as engineering drill bits.
	JSD70 Features: The crystal form is relatively complete, hexahedron, with few impurities inside the crystal, and has higher static strength (Newtons), impact toughness (TI), and thermal stability (TTI), with good wear resistance. Applications: Suitable for cutting tools, drilling tools, brazing tools, and electroplating tools under higher working strength conditions; such as cutting and drilling concrete, hard granite (F=10), high-grade ceramic tiles, and high-hardness refractory materials, as well as heavy-duty grinding tools and medium to high-load electroplating brazing tools.
	JSD60 Features: The crystal form is relatively complete, hexahedron, with relatively few impurities inside the crystal, and has medium static strength (Newtons), impact toughness (TI), and thermal stability (TTI), balancing wear resistance and sharpness. Applications: Suitable for high-speed cutting and drilling under moderate working strength conditions, such as cutting and drilling non-reinforced cement pavement, hard marble, and low-hardness granite (F=8), large quantities of building materials, refractory materials, and non-ferrous metal materials, as well as heavier grinding tools and medium-load electroplating brazing tools.
	JSD50 Features: The crystal form is relatively regular, hexahedron, with moderate impurity content inside the crystal, and has general static strength (Newtons), impact toughness (TI), and thermal stability (TTI), with moderate wear resistance and good sharpness. Applications: Suitable for high-speed cutting and drilling under medium to low working strength conditions, such as cutting and drilling soft marble and sandstone (F=6-5), glass, ceramics, and batch building materials, as well as medium-load grinding tools and low-load electroplating tools.
	JSD40 Features: The crystal form is 90-95% regular, with moderate impurity content inside the crystal, and has lower static strength (Newtons), impact toughness (TI), and thermal stability (TTI), with moderate wear resistance and good sharpness. Applications: Suitable for high-speed cutting and drilling under low working strength conditions, such as small diameter free cutting and drilling tools; as well as medium to low-load grinding tools and low-load electroplating tools.
	JSD30 Features: The crystal form is 85% regular, with more impurities inside than JSD40, and has lower static strength (Newtons), impact toughness (TI), and thermal stability (TTI), with poor wear resistance and very good sharpness. Applications: Suitable for good sharpness small diameter free cutting tools and drilling tools, such as gems, jade, crystals, and small batches of stone, glass, and tiles cutting and drilling; as well as medium to low-load grinding tools and low-load electroplating tools.
	JSD20 Features: The crystal form is 70% regular, with more impurities inside, rough surface, low static strength (Newtons), impact toughness (TI), and thermal stability (TTI), with poor wear resistance and excellent sharpness. Applications: Suitable for good sharpness small diameter free cutting tools and drilling tools, medium to high-load ceramic bonding tools, low-load metal bonding grinding tools, and high sharpness electroplating tools; used for processing hard alloys, magnetic materials, glass, tiles, crystals, gemstones, and other brittle materials; can also be used with high-grade diamonds to adjust tool sharpness.
	JSD10 Features: The crystal form is 50% regular, with more impurities inside, rough surface, very low static strength (Newtons), impact toughness (TI), and thermal stability (TTI), with poor wear resistance, excellent sharpness, and good self-sharpness. Applications: Suitable for medium to high-load resin bonding tools, medium to low-load
