SUMIDIA Series

- General Features

SUMIDIA is a polycristalline diamond material developed by

using our proprietary technologies.

SUMIDIA is available in two grades: DA1000 and DA150, 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 aluminium alloys to brittle materials such as carbide. - Series Features Application

GradeFeaturesApplicationAverage size of Diamond grains (µm)Hardness HvTRS (GPa)
DA1000 IDIAHigh density sintered material made of ultra-fine diamond particles that demonstrates optimum wear resistance, andexcellent edge sharpness.•High Silicon Aluminum Alloy Cutting •Rough, Interrupted and Finishing of Al-alloy •Wood or Wooden Board Cutting •Non-Ferrous Metal finishing (Aluminium, Copper Alloy)~ 0,5110 120 ~≈ 2,60
DA150 SUMMicro-grained sintered diamond grade with strong diamond-to-diamond bonding. It is suitable for the machining of non-ferrous metals and other veryhard materials.•Non-Ferrous Metal finishing (Aluminium, Copper Alloy) •Green or Semi-Sintered Carbide & Ceramic Roughing • FRP, Hard Rubber & Carbon Cutting • Wooden or Inorganic Material Board Cutting5100 120 ~≈ 1,95
NPD10 SUMIDIA Binderless NewA 100% diamond grade made by nano-level diamond grains with direct conversion sintering. Has the highest wear resistance and fracture resistance and the best edge sharpness.•Surface finishing of carbide •Machining brittle materials (ceramics)< 0,5120 130 ~≈ 3,15
