Natural diamond abrasive grains
synthetic diamond for Metal bond
Natural diamond abrasive grains
Natural diamonds, which do not contain catalysts or metallic components used in the production of synthetic diamonds, are characterized by excellent friability and a sharp cutting edge. Due to their low metallic content, they are suitable as raw materials for electroplated tools and can also be used as free-standing abrasive grains.
Furthermore, because this product is of natural origin, quality control is more challenging compared to synthetic diamonds; however, the natural diamonds we handle are characterized by consistent quality from identified sources.
We offer sizes ranging from saw-cut to micron-sized, and we maintain stock for certain sizes.
