Built with 3M Precision Shaped Grain, this 4.5-inch, 80-grit disc delivers faster cut rates and cooler grinding temperatures compared to conventional fibre discs. A built-in grinding aid actively reduces heat buildup, making it well suited for heat-sensitive alloys. Stiff fibre backing paired with a strong resin bond provides durability and tear resistance through demanding applications. Licensed trades and metalworking professionals install this disc for weld removal, blending, beveling, edge chamfering, and finish refinement work.\u003c\/p\u003e\u003cp\u003eThis disc is designed for use on stainless steel and high nickel alloys in both fabrication shop and field environments. Typical applications include weld grinding, bevel preparation, and surface blending where heat control and consistent cut rate are critical. The Quick Change mount system allows fast disc swaps without tools, reducing downtime during production or repair work. At 4.5 inches in diameter and 80 grit, it fits common right-angle grinder workflows used in industrial, structural, and process piping applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3M Precision Shaped Grain provides higher cut rates and cooler grinding versus conventional fibre discs\u003c\/li\u003e\n\u003cli\u003eBuilt-in grinding aid minimizes heat buildup on heat-sensitive alloys such as high nickel grades\u003c\/li\u003e\n\u003cli\u003eStiff fibre backing and strong resin bond resist tearing under heavy grinding loads\u003c\/li\u003e\n\u003cli\u003eQuick Change attachment system enables fast, tool-free disc replacement\u003c\/li\u003e\n\u003cli\u003eEffective for weld removal, 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\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 RPM rating before mounting. Power down and disconnect the grinder from its power source before changing discs. Always use appropriate eye, face, and hand protection when operating abrasive discs, and ensure the work area is clear of flammable materials given the sparks produced during grinding.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 4.5 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 Grain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment Style\u003c\/strong\u003e: Quick Change\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 6.421 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: 076308896510\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: 7100099277\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346460836146,"sku":"7100099277","price":522.36,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310536037.jpg?v=1782080890","url":"https:\/\/voomisupply.com\/products\/3m-7100099277-quick-change-fibre-disc-80-grit-4-5-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
