DA90 PCD grade




The PCD grade DA90 is our first recommendation for roughing of cemented carbides and hard and brittle materials.

  • A grade made by sintering rough-grained polycrystalline diamond which contains the highest amount of diamond
  • Achieves stable tool life by excellent wear resistance
  • Cost performance achieved by optimal design and development of mass production technology, utilizing the SUMIDIA NF

Application Range

Achieves stable tool life for rough machining of carbide

  • Stable long tool life based on the coarse-grained, polycrystalline diamonds
  • Cost advantages compared to grinding
  • Cemented carbides with a binder content from 6% can be machined
