Designated as the 787C, it uses 3M Precision Shaped Grain, a ceramic abrasive engineered to cut faster and run cooler than conventional abrasive minerals. At 7 inches in diameter and 36 grit, this disc is designed for heavy stock removal. A grinding aid is incorporated into the disc construction to reduce heat buildup at the workpiece surface, making it well suited for heat-sensitive alloys. The stiff fibre backing and strong resin bond provide tear resistance under sustained load. Licensed trade professionals and fabricators use this disc with angle grinders and disc grinders in production and field settings.\u003c\/p\u003e\u003cp\u003eThe 787C disc targets weld removal, blending, beveling, edge chamfering, and finish refinement on stainless steel and high nickel alloys. Its Precision Shaped Grain delivers higher cut rates per disc than conventional fibre discs, reducing disc changes and downtime in high-volume fabrication or maintenance work. The grinding aid is particularly valuable when working with heat-sensitive base materials where discoloration or metallurgical changes are a concern. This disc is sold individually and requires a compatible disc pad face plate or hub, sold separately.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3M Precision Shaped Grain delivers faster cut rates and cooler grinding compared to conventional abrasive minerals\u003c\/li\u003e\n\u003cli\u003e36 grit ceramic abrasive suited for heavy stock removal, weld grinding, and beveling\u003c\/li\u003e\n\u003cli\u003eGrinding aid reduces heat buildup at the surface, protecting heat-sensitive alloys\u003c\/li\u003e\n\u003cli\u003eStiff fibre backing with strong resin bond resists tearing under sustained grinding loads\u003c\/li\u003e\n\u003cli\u003e7 inch diameter fits standard disc grinders and angle grinders with appropriate backing pads\u003c\/li\u003e\n\u003cli\u003eCompatible with 3M disc pad face plates and hubs, sold separately\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with 3M disc pad face plates and hubs sold separately.

Verify the disc speed rating meets or exceeds the grinder's maximum RPM before mounting. Use the correct backing pad or hub as specified by the tool manufacturer. Inspect the disc for damage before each use and do not use a disc that shows cracks, tears, or delamination.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 36\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Precision Shaped Ceramic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Construction\u003c\/strong\u003e: Coated fibre disc with grinding aid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 9.84 inches x 8.7 inches x 8.95 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 2.642 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 051125872572\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: 3M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7100109878\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51345157587250,"sku":"7100109878","price":137.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310530314.jpg?v=1782050763","url":"https:\/\/voomisupply.com\/products\/3m-7100109878-fibre-disc-787c-7-inch-36-grit-ceramic","provider":"Voomi Supply","version":"1.0","type":"link"}
