Built with a closed-coat construction and 36 plus grit ceramic abrasive, this disc cuts fast and stays sharp longer than conventional aluminum oxide alternatives. The resin bond holds the abrasive firmly under load, supporting a rated speed of 1200 RPM. Designed for use with standard angle grinders and disc grinders, these discs fit a 7\/8 inch unthreaded arbor hole on a 5 inch diameter backing. Each case contains 100 discs, making this a practical stock item for shops and field crews running high-volume grinding operations.\u003c\/p\u003e\u003cp\u003eThis disc is suited for fabrication shops, structural steel work, pipe fitting, and general metal grinding where stock removal rate matters. The 36 plus grit designation targets rough grinding, deburring, and weld blending on ferrous and non-ferrous metals. Closed-coat coverage maximizes abrasive surface contact for consistent cut rate across the face of the disc. Trades commonly using this product include ironworkers, pipefitters, welders, and sheet metal mechanics.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic abrasive grain for faster cut and longer disc life compared to conventional abrasives\u003c\/li\u003e\n\u003cli\u003eClosed-coat construction maximizes abrasive coverage for consistent stock removal\u003c\/li\u003e\n\u003cli\u003eResin bond system holds grain firmly under aggressive grinding pressure\u003c\/li\u003e\n\u003cli\u003e36 plus grit rating suited for heavy stock removal and weld blending\u003c\/li\u003e\n\u003cli\u003eRated at 1200 RPM for standard angle and disc grinder applications\u003c\/li\u003e\n\u003cli\u003e100 discs per case for high-volume production and field use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with angle grinders and disc grinders accepting a 5 inch diameter fiber disc with a 7\/8 inch unthreaded arbor hole.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMounting and disc changes should be performed with the grinder disconnected from power. Verify the grinder's rated RPM meets or exceeds the disc's 1200 RPM rating before use. Inspect the disc for damage before each use and do not use a disc that shows cracks, tears, or delamination. Always use the appropriate guard and follow applicable ANSI B7.1 safety standards for abrasive wheel use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Cubitron 3 1187C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 36 Plus\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Coverage\u003c\/strong\u003e: Closed Coat\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 7\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Hole Type\u003c\/strong\u003e: Unthreaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRated Speed\u003c\/strong\u003e: 1200 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 100 per Case\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.762 pounds\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: 7100308532\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344071164210,"sku":"7100308532","price":727.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310551883.jpg?v=1782028301","url":"https:\/\/voomisupply.com\/products\/3m-7100308532-cubitron-3-1187c-fiber-disc-36-grit-5-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
