Mesh size
Here we introduce synthetic diamond powders in mesh sizes ranging from #60 to #500, which are primarily used in grinding wheels. Based on the type of binder used, these products are broadly categorized into metal-bonded and resin-bonded types. For abrasive grains coarser than #60—used in cutting and processing concrete, stone, and other materials—please refer to our “Other Products” section.
synthetic diamond for Resin bond
Resin-based synthetic diamonds
Synthetic diamonds developed for resin-bonded applications are characterized by their irregular shapes, which increase surface area to prevent them from falling out of the resin binder.
They also exhibit excellent friability, making them abrasive grains that are expected to generate new cutting edges on their own. Additionally, they generally have a blackish-gray color.
They also exhibit excellent friability, making them abrasive grains that are expected to generate new cutting edges on their own. Additionally, they generally have a blackish-gray color.
We can recommend the optimal abrasive grain from our extensive lineup of resin-bonded diamonds.

synthetic diamond for Metal bond
Metal-based synthetic diamonds
Metal-bonded synthetic diamonds are made from abrasives with higher toughness than those used in resin-bonded products. They typically range in color from yellow to yellow-green and are characterized by a blockier shape compared to resin-bonded abrasives. The fewer internal impurities and the more solid and blocky the crystals, the greater the heat resistance and strength.
We offer a wide selection of products classified by shape and magnetic properties, and we will recommend the optimal abrasive for your needs.
