Polycrystalline Diamond Tools

Series

• General Features

SUMIDIA is a polycrystalline diamond material developed by using our

proprietary technologies.

SUMIDIA is available in 4 grades (DA90, DA150, DA2200 and DA1000), each

having different characteristics depending on the size of the diamond grains

and the combination of binder materials.

In addition, a new grade (NPD10) made by nano-level diamond grains without

binder material with direct conversion sintering has been newly added to our

product line.

SUMIDIA can be used for all types of applications, from machining

aluminum alloys to brittle materials such as carbide.
