Description:

3M Ceramic Precision-Shaped Grain (PSG) maintains super-sharp points that cut exceptionally fast with less pressure. PSG runs cooler and disc life is significantly longer, completing more parts per disc and requiring fewer disc changes. Stiff fiber backing and a strong resin bond provide durability and tear-resistance for heavyweight applications and can be used wet or dry. Grinding aid incorporated on the disc minimizes grinding temperatures for heat-sensitive alloys.
