It uses 3M Precision Shaped Grain, a ceramic abrasive geometry that delivers higher cut rates and cooler grinding temperatures compared to conventional fibre discs. A built-in grinding aid further reduces heat buildup, making this disc well suited for heat-sensitive alloys. The stiff fibre backing and strong resin bond resist tearing under load. This disc is installed and used by metal fabricators, welders, and maintenance tradespeople who require consistent, aggressive material removal in production environments.\u003c\/p\u003e\u003cp\u003eThe 787C disc is designed for weld removal, blending, bevel grinding, edge chamfering, and finish refinement on stainless steel and high nickel alloys. Its Precision Shaped Grain construction maintains cut rate over the life of the disc, reducing the need for frequent disc changes and helping control abrasive cost per part. It is appropriate for both shop fabrication and field maintenance applications where surface quality and throughput both matter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePrecision Shaped Ceramic Grain provides higher cut rates and cooler grinding versus conventional abrasive minerals\u003c\/li\u003e\n\u003cli\u003eBuilt-in grinding aid minimizes heat generation on stainless steel and high nickel alloys\u003c\/li\u003e\n\u003cli\u003eStiff fibre backing and strong resin bond resist tearing under heavy grinding loads\u003c\/li\u003e\n\u003cli\u003eSuited for weld grinding, beveling, edge chamfering, and surface blending\u003c\/li\u003e\n\u003cli\u003eCompatible with 3M disc pad face plates and hubs (sold separately)\u003c\/li\u003e\n\u003cli\u003eLong disc life reduces abrasive cost per finished part\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 that the grinder RPM rating meets or exceeds the disc maximum RPM rating before use. Always wear appropriate PPE including eye protection and gloves. Inspect the disc for damage before each use and do not use a disc that shows tears, cracks, or delamination.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Precision Shaped Ceramic Grain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking\u003c\/strong\u003e: Fibre\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Weld removal, blending, beveling, edge chamfering, finish refinement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Materials\u003c\/strong\u003e: Stainless steel, high nickel alloys\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 4.433 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 11.13 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 6.95 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 6.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 638060303950\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: 7100185246\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344003465522,"sku":"7100185246","price":416.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310519691.jpg?v=1782026571","url":"https:\/\/voomisupply.com\/products\/3m-7100185246-fibre-disc-787c-5-inch-80-grit-ceramic","provider":"Voomi Supply","version":"1.0","type":"link"}
