It uses 3M Precision Shaped Grain, a ceramic abrasive mineral that delivers faster cut rates and a cooler grinding action compared to conventional fibre discs. A built-in grinding aid further reduces heat buildup, making this disc well suited to heat-sensitive materials such as stainless steel and high nickel alloys. The 120-grit designation targets blending, finish refinement, and weld removal. Fabricators, welders, and metal finishing technicians working in industrial and manufacturing environments are the primary users of this product.\u003c\/p\u003e\u003cp\u003eThis disc is designed for demanding metalworking applications including weld grinding, beveling, edge chamfering, and surface blending on stainless steel and high nickel alloys. Its stiff fibre backing and strong resin bond resist tearing under heavy lateral loads, making it appropriate for both handheld angle grinders and disc pad setups. It is sold individually and requires a compatible disc pad face plate and hub, which are sold separately.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePrecision Shaped Grain ceramic mineral provides higher cut rates and cooler operating temperatures than conventional abrasive grains\u003c\/li\u003e\n\u003cli\u003eIntegrated grinding aid reduces heat generation during use on heat-sensitive alloys\u003c\/li\u003e\n\u003cli\u003eStiff fibre backing and heavy-duty resin bond deliver durability and tear resistance under sustained load\u003c\/li\u003e\n\u003cli\u003e120 grit is optimized for weld removal, surface blending, and finish refinement\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 spindle speed rating of the grinder does not exceed the maximum RPM rating of the disc before mounting. Wear appropriate PPE including face shield, gloves, and hearing protection during operation. Inspect the disc for damage before each use and discard any disc showing cracks, tears, or delamination.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 3 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 Ceramic Grain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking\u003c\/strong\u003e: Stiff Fibre\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resin\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: 2.233 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 11.21 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: 0638060398777\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: 7100200272\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344903471410,"sku":"7100200272","price":267.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310519824.jpg?v=1782044992","url":"https:\/\/voomisupply.com\/products\/3m-7100200272-fibre-disc-787c-3-inch-120-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
