987C offers significant gains in productivity on medium to heavy-duty operations with our exceptionally high-performing 3M Precision Shaped Grain combined with a stiff fiber backing. This disc achieves a higher cut-rate, greater durability, and longer life than other fiber discs—all with less grinding pressure.
Designed for stainless steel and other heat-sensitive applications, the proprietary 3M Precision Shaped Grain technology improves disc life (up to 2 times or more), cuts faster and can increase productivity compared to other leading ceramic discs. Takes time out of edge chamfering, bevelling and removing stainless steel welds, mill scale, pits and imperfections, machining grooves and more to deliver a lower cost per grind.
Features
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
A grinding aid incorporated on the disc minimizes grinding temperatures for heat-sensitive alloys like stainless steel, titanium, and nickel alloys
