At 7 inches in diameter with a 60-grit abrasive rating and a maximum operating speed of 8600 RPM, this disc uses 3M Precision-Shaped Grain technology to maintain consistently sharp cutting points throughout the life of the disc. The result is a faster cut rate, lower grinding pressure, and significantly longer disc life compared to conventional aluminum oxide fiber discs. A stiff fiber backing and strong resin bond add tear resistance under high-pressure conditions.\u003c\/p\u003e\u003cp\u003eThis disc is suited for fabrication shops, structural steel work, and robotic or pressure-assisted grinding systems where throughput and disc longevity directly affect labor costs. Typical applications include weld seam removal, surface conditioning, and edge beveling on ferrous and heat-sensitive alloys. The integrated grinding aid helps manage heat buildup, making it appropriate for stainless steel and other alloys where discoloration or heat distortion is a concern. Licensed trades and production grinders working with angle grinders and backup pads are the primary installers and users.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3M Precision-Shaped Grain maintains sharp cutting points for fast stock removal with less applied pressure\u003c\/li\u003e\n\u003cli\u003eIntegrated grinding aid reduces heat generation, extending disc life on heat-sensitive alloys such as stainless steel\u003c\/li\u003e\n\u003cli\u003eStiff fiber backing and strong resin bond provide tear resistance in high-pressure weld grinding and beveling\u003c\/li\u003e\n\u003cli\u003eRated to 8600 RPM for use with standard angle grinders and backup pads\u003c\/li\u003e\n\u003cli\u003eSuitable for robotic and pressure-assisted grinding applications, reducing changeouts and downtime\u003c\/li\u003e\n\u003cli\u003e60-grit abrasive profile balances aggressive stock removal with acceptable surface finish on heavy-duty operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 7-inch angle grinders and compatible backup pads in medium to heavy-duty grinding, weld removal, and beveling operations on ferrous metals and heat-sensitive alloys.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eFiber discs must be mounted on a rigid or semi-rigid backup pad matched to the disc diameter before use on an angle grinder. Verify the grinder free-speed does not exceed the disc maximum RPM rating before mounting. Inspect the disc for cracks, tears, or damage before each use and discard any compromised disc immediately. Follow ANSI B7.1 and tool manufacturer guidelines for abrasive disc mounting and guarding requirements.\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\u003eGrit\u003c\/strong\u003e: 60\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 Fiber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Mineral\u003c\/strong\u003e: Precision-Shaped Grain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 10.403 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 13.09 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\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 638060297853\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: 7100178295\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51347647627570,"sku":"7100178295","price":712.88,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310519537.jpg?v=1782110457","url":"https:\/\/voomisupply.com\/products\/3m-7100178295-cubitron-ii-987c-fiber-disc-7-in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
