It uses 3M Precision Shaped Grain, an engineered abrasive mineral that delivers higher cut rates and cooler grinding temperatures compared to conventional fibre discs. The disc measures 9.125 inches in diameter with a 0.875 inch arbor hole and carries a 120 grit rating, making it well suited for aggressive material removal followed by controlled surface refinement. A built-in grinding aid reduces heat buildup at the workpiece, which is critical when working stainless steel and high nickel alloys where heat-induced discoloration or metallurgical changes are concerns.\u003c\/p\u003e\n\u003cp\u003eThis disc is used in fabrication, maintenance, and manufacturing environments where weld grinding, blending, beveling, and edge chamfering are routine tasks. It performs on stainless steel and high nickel alloys, materials that load and glaze conventional abrasives quickly. Typical users include metal fabricators, industrial maintenance technicians, and pipefitters working on code-sensitive or finish-sensitive assemblies. The stiff fibre backing and strong resin bond handle the lateral forces generated during angle grinder work without tearing or delaminating prematurely.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3M Precision Shaped Grain provides higher cut rates and cooler grinding action than conventional abrasive minerals\u003c\/li\u003e\n  \u003cli\u003eGrinding aid minimizes heat buildup, protecting heat-sensitive alloys like stainless steel and high nickel alloys\u003c\/li\u003e\n  \u003cli\u003eStiff fibre backing and strong resin bond resist tearing and delamination under heavy load\u003c\/li\u003e\n  \u003cli\u003e120 grit rating supports weld removal, surface blending, and finish refinement in a single disc\u003c\/li\u003e\n  \u003cli\u003eCompatible with 3M disc pad face plates and hubs, sold separately\u003c\/li\u003e\n  \u003cli\u003eLonger disc life reduces per-part abrasive cost compared to conventional fibre discs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with 3M disc pad face plates and hubs sold separately.

Verify the grinder RPM rating meets or exceeds the disc maximum before mounting. Power down and disconnect the grinder from its power source before changing discs. Wear appropriate PPE including face shield and gloves, and inspect the disc for damage before each use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 9.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Size\u003c\/strong\u003e: 0.875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 120\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\u003ePackage Weight\u003c\/strong\u003e: 20.384 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 10.71 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 10.07 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 10.95 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 076308896572\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 7100099282\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51343274180914,"sku":"7100099282","price":653.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310536070.jpg?v=1782019729","url":"https:\/\/voomisupply.com\/products\/3m-7100099282-fibre-disc-787c-120-grit-9-125-in-coated","provider":"Voomi Supply","version":"1.0","type":"link"}
