Harder than single-crystal diamond, it has no cleavability, enabling machining SUMIDIABinderless Ultra-hard with no anisotropy of hard brittle material such as cemented carbide and making new machining methods possible. Single-crystalDiamond Hardness depends on crystal orientation I ■ Features Conventional · SUMIDIA Binderless is a pure diamond material, but unlike PCD Load 4.9N single-crystal diamonds, it has no anisotropy. It therefore 0 50 100 150 displays excellent wear resistance with less uneven wear. Knoop Hardness HK (GPa) · Thanks to its polycrystalline structure, SUMIDIA Binderless does not have the cleavability peculiar to single-crystal ● Hemispherical Surface Milling diamonds and displays excellent fracture resistance.
