Built around a premium ceramic alumina grain bonded with a resinoid bond to a fiber backing, this disc delivers consistent cut rates and extended service life compared to conventional aluminum oxide discs. At 36 grit, it falls in the extra coarse grade range, making it well-suited for heavy stock removal, weld blending, and surface prep work. The TN quick-change attachment allows fast disc swaps without wrenches, reducing downtime during production or field grinding operations. Rated to a maximum of 13,300 RPM, the disc is engineered for use with compatible right-angle grinders and disc sanders.\u003c\/p\u003e\n\u003cp\u003eThis disc is used in fabrication shops, metal service centers, and field maintenance environments where high-volume grinding on steel, stainless steel, and other hard metals is required. The 4.5-inch diameter fits a standard disc tool footprint common across industrial and trade applications. The extra coarse 36 grit makes it the right choice for initial weld seam removal, heavy scale grinding, and aggressive surface conditioning before moving to finer abrasives. Licensed tradespeople in pipefitting, ironwork, and structural fabrication will find this disc appropriate for daily production grinding tasks.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePremium ceramic alumina grain for high cut rate and extended disc life\u003c\/li\u003e\n  \u003cli\u003e36 grit extra coarse grade optimized for heavy stock removal and weld blending\u003c\/li\u003e\n  \u003cli\u003eTN quick-change attachment for tool-free disc changes on compatible grinders\u003c\/li\u003e\n  \u003cli\u003eFiber backing material provides durability and conformability under load\u003c\/li\u003e\n  \u003cli\u003eResinoid bond holds grain securely through demanding grinding cycles\u003c\/li\u003e\n  \u003cli\u003eMaximum rated speed of 13,300 RPM for safe use on standard angle grinders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with right-angle grinders and disc sanders that accept TN quick-change style fiber disc attachments with a 4.5-inch disc capacity.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and disc changes should be performed by qualified personnel familiar with angle grinder safety procedures. Always power down and disconnect the grinder from its power source before mounting or removing a disc. Verify the grinder RPM rating meets or exceeds the disc maximum rated speed of 13,300 RPM before operation. Inspect the disc for damage prior to each use and follow applicable ANSI B7.1 grinding wheel safety standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 36\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Extra Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Premium Ceramic Alumina\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Quick-Change TN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Fiber\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resinoid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Purple\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 13,300\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1182C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31191506\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 7100310727\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51538893766962,"sku":"7100310727","price":372.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/915ebc92a06c588db3dc15bea41e97ea.jpg?v=1785828920","url":"https:\/\/voomisupply.com\/products\/3m-7100310727-fiber-disc-4-1-2-in-36-grit-ceramic-quick-change","provider":"Voomi Supply","version":"1.0","type":"link"}
