• Saw Grade Diamond
    • SDG series is a kind of saw grade industrial diamond product for sawing of stone, concrete and geological drilling. This type product is suitable for making frame saw, wire saw, multi-blades and drill bits. Workpieces range from hardest granite, asphalt, refractories and reinforced concrete to softer marbles, limestones and lightweight building materials.
    • The premium grade SDG5190, 5180, 5160 are ranked the prefect cubo-octahedral crystalline, the crystal also have favorable transparency and purity, highest toughness, perfect thermal stability and impact resistance.
    • The medium grade SDG5140, 5130 are ranked the high percentage of whole cubo-octahedral crystalline, low inclusion and high toughness.
    • The economic grade SDG5125,5120,5115 and 5110 are designed for medium load application, the whole crystalline percentage is lower than above two types.
    • The coarse grit SDG52xx series from top grade SDG5290 to economic grade SDG5215, can match different working applications like high strength saw, drill and grinding tools, rope saw as well as for the electroplated tools, medium load or low load tools making.

  • SDG 5190  
    With the most accordant crystal color, excellent controled shape, very good transparency, high strength and great thermal stability, it is suitable for making tools for sawing or grinding hard stone like granite, asphalt and reinforced concrete, also suitable for geological drills. SDG 5190
