Built around 3M Precision Shaped Grain, this 787C disc delivers higher cut rates and a cooler cut compared to conventional fibre discs. At 4.5 inches in diameter and 60 grit, it is engineered for heavy-duty grinding tasks such as weld removal, blending, and finish refinement. A grinding aid is incorporated into the construction to minimize heat buildup, making it well suited for heat-sensitive alloys. Licensed tradespeople and fabricators working in metal fab, shipbuilding, and industrial maintenance are the primary installers.\u003c\/p\u003e\u003cp\u003eThis disc is used across a range of metalworking applications where aggressive stock removal and consistent finish are both required. Typical uses include weld grinding, beveling, edge chamfering, and surface blending on stainless steel and high nickel alloy components. It is appropriate for both shop and field use on angle grinders equipped with compatible quick-change disc pads. The stiff fibre backing and strong resin bond provide durability and tear resistance through demanding workloads.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3M Precision Shaped Grain provides higher cut rates and a cooler cut than conventional fibre discs\u003c\/li\u003e\n\u003cli\u003eGrinding aid minimizes heat buildup for use on heat-sensitive alloys\u003c\/li\u003e\n\u003cli\u003eStiff fibre backing and strong resin bond deliver durability and tear resistance\u003c\/li\u003e\n\u003cli\u003eCompatible with 3M disc pad face plates and hubs, sold separately\u003c\/li\u003e\n\u003cli\u003e4.5 inch diameter at 60 grit targets heavy-duty weld grinding and blending tasks\u003c\/li\u003e\n\u003cli\u003eLong-lasting disc construction helps lower cost per 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 angle grinder RPM rating meets or exceeds the disc RPM rating before use. Always use the appropriate guard and personal protective equipment, including a face shield, when operating. Inspect the disc for damage before each use and do not use a disc that is torn, cracked, or deformed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Precision Shaped Grain, Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking\u003c\/strong\u003e: Stiff Fibre\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment Style\u003c\/strong\u003e: Quick Change\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: 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 6.721 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 21.59 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 6.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 6.95 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 076308896428\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: 7100099244\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346350145842,"sku":"7100099244","price":556.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310535996.jpg?v=1782078106","url":"https:\/\/voomisupply.com\/products\/3m-7100099244-fibre-disc-60-grit-4-5-inch-quick-change-787c","provider":"Voomi Supply","version":"1.0","type":"link"}
