■ General Features ■ Hardness SUMIDIA Binderless is a type of polycrystalline diamond, produced by directly binding nano-order diamond grains without using any binders.

SUMIDIA No anisotropy and ultra-hard SUMIDIA Binderless is harder than single-crystal diamond and Binderless

has no cleavability. Therefore, it enables machining of hard, brittle

materials such as carbides and enables new machining methods. Single Crystal Diamond Hardness depends on face orientation

■ Characteristic

Conventional PCD

  • SUMIDIA Binderless is a pure diamond, but unlike single-crystal Load 4.9N

diamonds, has no anisotropy. Therefore, it displays excellent 0 50 100 150

wear resistance with less uneven wear. Knoop Hardness HK(GPa)

  • Thanks to its polycrystalline structure, SUMIDIA Binderless has no cleavability peculiar to single-crystal diamonds and displays excellent fracture resistance. Hemispherical Surface Milling
