3M Fibre Disc 987C, Precision Shaped Ceramic Grain, Wet/Dry, 7" Diameter, 80+ Grit, Orange (Pack of 25)

Product Description 3M's top performing Cubitron II fiber disc 987C raises the bar for durability. 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, beveling and removing stainless steel welds, mill scale, pits and imperfections, machining grooves and more to deliver a lower cost per grind. 111-128-inches center hole diameter. Coat type: closed coat. Converted form: fiber disc. Equipment - machines: right angle grinders. Form type: fiber. Max rpm: 8600. Max speed: 80 meter per second. Position: premium. Made of ceramic. Measures 7-inches diameter. 80+ Grit. Orange color. From the Manufacturer 3M Cubitron II Fibre Disc 987C is suitable for use on almost all metals and excels in stainless steel and other nickel alloy applications. It is ideal for weld removal, beveling, removing mill scale, pits and imperfections, and more. Because 3M Precision Shaped Grain generates an exceptionally high cut-rate with less pressure, operators can finish tough tasks faster and with less fatigue. A grinding aid incorporated on the disc makes this an outstanding product for all types of metal—it helps keep the disc cooler on stainless steel and heat-sensitive metals such as nickel alloys and titanium, thereby reducing metal discoloration/oxidation and the chance of heat-related stress cracks. Moreover, because the abrasive itself stays cooler and sharper, 3M Precision Shaped Grain discs last significantly longer than conventional ceramic grain discs, delivering a lower cost per grind with fewer disc changes.3M Cubitron II products have raised the bar for high-performing abrasives. 3M Precision Shaped Grain outcuts and outlasts conventional ceramic industrial abrasives and requires less grinding force to achieve superior performance. The result is that operators can grind faster and complete more parts per disc with less muscle-work and fatigue.To create 3M Precision Shaped Grain, engineers started with 3M Ceramic Abrasive Grain and used proprietary technology to form the grains into triangular structures and electrostatically orient them on the backing to form sharp peaks that maximize cutting potential. These peaks slice cleanly through metal, rather than gouging or plowing as traditional abrasives do, and continuously self-sharpen as the points break off. This generates a super-fast cut and lessens heat build-up due to friction, reducing heat-related stress cracks and discoloration.3M Precision Shaped Grain also wears evenly, and because the abrasive itself stays cooler and sharper, 3M Cubitron II products last significantly longer than their conventional ceramic counterparts, ensuring extended high performance in production applications.Fiber discs are heavy-duty discs ideal for weld removal, grinding, and blending large and small areas of metal surfaces. They feature a tough, stiff backing made from vulcanized fiber that resist wear and can handle tough grinding applications.

• 3M Ceramic 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
• Stiff fiber backing and a strong resin bond provide durability and tear-resistance for heavyweight applications such as high-pressure weld grinding, and can be used wet or dry
• Grinding aid incorporated on the disc minimizes grinding temperatures for heat-sensitive alloys
• 7/8 inch center hole mount is compatible with 3M disc pad face plates and hubs, and requires the use of a disc retainer nut (all sold separately)
• 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
