It uses 3M Precision-Shaped Grain, a ceramic abrasive mineral engineered to maintain sharp cutting points throughout the disc life. The result is a faster cut rate, lower grinding pressure, and extended disc life compared to conventional fiber discs. At 5 inches in diameter and 80 grit, it is suited to aggressive material removal while reducing heat buildup on heat-sensitive alloys. A stiff fiber backing and strong resin bond keep the disc stable under high-pressure load conditions.\u003c\/p\u003e\u003cp\u003eThis disc is built for professional fabrication and metalworking environments where productivity and disc longevity are critical. Typical applications include weld seam grinding, bevel preparation, and surface conditioning on steel and stainless steel. It is particularly effective in robotic grinding setups and pressure-assisted angle grinder applications where consistent cut performance and reduced changeout frequency are priorities. The integrated grinding aid helps manage heat during prolonged grinding passes on alloys prone to thermal distortion.\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 reduced grinding pressure\u003c\/li\u003e\n\u003cli\u003eCeramic mineral runs cooler, extending disc life and reducing the number of disc changes per job\u003c\/li\u003e\n\u003cli\u003eStiff fiber backing and strong resin bond provide tear resistance under high-pressure grinding loads\u003c\/li\u003e\n\u003cli\u003eIntegrated grinding aid minimizes heat generation, protecting heat-sensitive alloys during extended use\u003c\/li\u003e\n\u003cli\u003eRated to 12000 RPM, compatible with standard 5 inch angle grinders\u003c\/li\u003e\n\u003cli\u003eReduces downtime in robotic and pressure-assisted grinding applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on 5 inch angle grinders rated to a minimum of 12000 RPM.

Always verify the grinder speed rating meets or exceeds the disc maximum RPM before mounting. Ensure the grinder is fully powered off and unplugged before changing discs. Inspect the disc for cracks or damage before each use and never operate a damaged disc.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Speed\u003c\/strong\u003e: 12000 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Precision-Shaped Grain ceramic\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051141277325\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: 7010326434\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344432660786,"sku":"7010326434","price":646.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310532806.jpg?v=1782035910","url":"https:\/\/voomisupply.com\/products\/3m-7010326434-cubitrona-ii-987c-fiber-disc-80-grit-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
