This diamond grain is particularly suitable for the production of resin and vitrified bonded tools. The adhesion between the bonding webs is enhanced by its irregular shape, while providing a high Friability. This ensures a continuous self-sharpening process with very good free cutting properties. The uncoated grain is RVD is recommended for wet and dry grinding applications in the field of tungsten carbide and technical ceramics such as SiN and SiC.
