3M 987C Offers

This disk uses precision-shaped grain technology (PSG) for heavy duty metalworking applications. PSG is an exceptionally high-performing ceramic, resin-bonded to a stiff fiber backing.
The 3M Fibre products incorporate a grinding aid to keep the workpiece cooler, protecting heat-sensitive alloys from heat damage and reducing re-work. These features offer increased productivity for heavy-duty grinding on all metals, including stainless steel.

Features

• 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
• For medium to heavy-duty operations
• Stiff fiber backing
• This disc achieves a higher cut-rate, greater durability, and longer life than other fiber discs—all with less grinding pressure

Applications

• Heavy duty metalworking applications
