3M precision shaped ceramic grain (psg) maintains super-sharp points that cut exceptionally fast with less pressure compared to conventional abrasives. Disc life is significantly longer, completing more parts per disc and requiring fewer disc changes compared to conventional abrasives. 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. Yf-weight backing supports medium to high pressure grinding applications.
