Built around 3M Precision-Shaped Grain, the disc maintains sharp cutting points throughout its service life, delivering a higher cut rate at lower grinding pressure than conventional abrasive fiber discs. The stiff fiber backing and strong resin bond resist tearing under high-pressure applications. At 5 inches in diameter and rated to 12,000 RPM, this disc fits standard angle grinders and pressure-assisted or robotic grinding setups. A built-in grinding aid reduces heat buildup, making it suitable for heat-sensitive alloys and extended production runs.\u003c\/p\u003e\u003cp\u003eThis disc is suited for metal fabrication, structural steel work, weld removal, and beveling in both shop and field environments. It performs well in robotic grinding cells and pressure-assisted applications where consistent cut rate and reduced disc changeouts directly affect throughput. The 60 grit designation makes it appropriate for aggressive stock removal and weld seam grinding rather than finishing work. Metalworkers, fabricators, and maintenance technicians working on ferrous and heat-sensitive alloys are the primary installers and users of this disc.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3M Precision-Shaped Grain sustains sharp cutting points for fast material removal at reduced grinding pressure\u003c\/li\u003e\n\u003cli\u003eHigher cut rate and longer disc life reduce changeouts and downtime in production environments\u003c\/li\u003e\n\u003cli\u003eStiff fiber backing with strong resin bond provides tear resistance in high-pressure weld grinding and beveling\u003c\/li\u003e\n\u003cli\u003eIntegrated grinding aid minimizes disc and workpiece temperatures, protecting heat-sensitive alloys\u003c\/li\u003e\n\u003cli\u003eRated to 12,000 RPM for use with standard angle grinders and pressure-assisted grinding equipment\u003c\/li\u003e\n\u003cli\u003e5 inch diameter fits commonly available backing pads for angle grinder setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use fiber disc for 5 inch angle grinders and pressure-assisted grinding equipment that accept standard fiber disc backing pads.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eFiber discs of this type are mounted and changed by metalworkers and fabricators following standard abrasive safety practices. Always power down and disconnect the grinder before mounting or removing a disc. Verify the tool's maximum RPM rating meets or exceeds the disc rating before use. Inspect the disc and backing pad for damage before each use and discard any disc showing tears, cracks, or delamination.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 5 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: 12,000 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: 3M Precision-Shaped Grain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking\u003c\/strong\u003e: Stiff fiber\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e: Coated abrasive with resin bond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 8.64 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 11.13 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 6.69 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 051125873661\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: 7100170786\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51347796853042,"sku":"7100170786","price":619.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310530369.jpg?v=1782114015","url":"https:\/\/voomisupply.com\/products\/3m-7100170786-cubitron-ii-987c-fiber-disc-60-grit-5-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
