Features Back To Top
- 3M 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 such as high-pressure weld grinding or beveling
- Grinding aid incorporated on the disc minimizes grinding temperatures for heat-sensitive alloys
