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.
