SUMIDIA BINDERLESS PCD NPD10
Cutting edge is 100% diamond material made from high-hardness nano-crystalline diamond which, unlike single-crystal diamonds, has no anisotropy. Achieves longer tool life and higher machining accuracy than conventional diamonds in the machining of cemented carbide and other hard brittle materials.
The outstanding wear resistance of nano-polycrystalline diamond enables high-precision machining of cemented carbides Ideal for Finishing of Cemented Carbide and other Hard Brittle Materials Compared to conventional diamond tools, the number of tool changes is drastically reduced, improving work efficiency and reducing total costs. Maintains Excellent Dimensional Accuracy for Long Periods
◦ Nano-Polycrystalline Diamond Nano-polycrystalline diamond is a polycrystalline diamond that directly binds nano-order diamond particles with high strength without using any binders. Harder than single-crystal diamond, it has no cleavability, enabling machining of hard brittle materials such as cemented carbide and making new machining methods possible.
