SUMIDIA Binderless
Nano-Polycrystalline Diamond
■ General Features
Nano-polycrystalline diamond is a type of polycrystalline diamond, produced
by directly binding nano-level diamond grains without using any binders.
This material is unique to our company, and as compared to
conventional diamond grades containing binders, it exhibits higher
strength, excellent wear resistance and fracture resistance.
SUMIDIA Binderless is the series of tools with cutting edges made
from this high performance nano-polycrystalline diamond.
