It measures 7 inches in diameter with a 7\/8-inch arbor and carries a 120-grit rating. The disc is built around 3M Precision Shaped Grain, a mineral geometry that delivers higher cut rates and cooler grinding temperatures compared to conventional fibre discs. A grinding aid is built into the construction to further reduce heat buildup, making this disc well suited for heat-sensitive alloys. Maximum operating speed is 8600 RPM. Licensed trades using angle grinders for weld removal, blending, and surface refinement will find this disc a direct working tool.\u003c\/p\u003e\u003cp\u003eThis disc is intended for aggressive grinding applications on stainless steel and high nickel alloys in fabrication, maintenance, and repair environments. Typical applications include weld removal, weld blending, beveling, edge chamfering, and finish refinement. The stiff fibre backing and strong resin bond resist tearing under heavy lateral load. It is compatible with 3M disc pad face plates and hubs, which are sold separately. The disc is sold individually (UOM: Each), with a minimum order quantity of 100 units.\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\u003eIntegrated grinding aid minimizes heat buildup for use on heat-sensitive stainless steel and high nickel alloys\u003c\/li\u003e\n\u003cli\u003eStiff fibre backing and strong resin bond deliver durability and tear resistance under heavy load\u003c\/li\u003e\n\u003cli\u003eSuited for weld grinding, beveling, edge chamfering, and finish blending\u003c\/li\u003e\n\u003cli\u003e7 inch diameter, 120 grit, 7\/8 inch arbor — fits standard angle grinder configurations\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 grinder is rated at or above 8600 RPM before mounting. Inspect the disc for damage before each use and never operate a cracked or torn disc. Power down and disconnect the tool from its power source before mounting or removing the disc, and confirm the arbor size matches before securing.\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\u003eArbor Size\u003c\/strong\u003e: 7\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 120\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Speed\u003c\/strong\u003e: 8600 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Type\u003c\/strong\u003e: Coated Fibre\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Mineral\u003c\/strong\u003e: 3M Precision Shaped Grain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.13 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 9.84 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 8.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 8.95 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUOM\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00076308896560\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: 7100099281\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51347472810290,"sku":"7100099281","price":491.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310536033.jpg?v=1782106042","url":"https:\/\/voomisupply.com\/products\/3m-7100099281-fibre-disc-787c-7-inch-120-grit-coated","provider":"Voomi Supply","version":"1.0","type":"link"}
