Description:

3M Precision-Shaped Grain (PSG) maintains super-sharp points that cut exceptionally fast with less pressure. Disc life is significantly longer, completing more parts per disc and requiring fewer disc changes. Grinding aid incorporated on the disc minimizes grinding temperatures for stainless steel and other heat-sensitive alloys. Roloc quick attachment system provides for easy disc changes between grades or applications. Backing supports medium to high pressure grinding applications and 2-ply construction provides added durability for edge work.
