Part of the 947A series, this disc is constructed with a ceramic abrasive grain bonded to a polyester cloth backing rated at X-weight for durability under load. At 80 grit, it falls in the medium grade range, making it well suited for aggressive stock removal, weld blending, and surface conditioning on metal substrates. It is rated to a maximum of 20,000 RPM. The disc measures 3 inches in diameter and weighs approximately 0.01 pounds. It is installed and used by metal fabricators, maintenance technicians, and welders working with right-angle grinders or die grinders fitted with a compatible Type S mandrel.\u003c\/p\u003e\n\u003cp\u003eThis disc fits typical production and maintenance grinding applications in fabrication shops, HVAC equipment manufacturing, and general metalworking environments. The ceramic abrasive cuts aggressively and resists heat buildup, making it effective on stainless steel, carbon steel, and high-alloy materials. The maroon disc color and silver button are standard identifiers for this series. Single-disc packaging suits spot replacement or trial use. It is appropriate for both bench and field service work where quick disc changes are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic abrasive grain for aggressive cut rate and long disc life on metal\u003c\/li\u003e\n  \u003cli\u003e80 grit medium grade suitable for stock removal and weld blending\u003c\/li\u003e\n  \u003cli\u003ePolyester cloth X-weight backing resists tearing under high-pressure grinding\u003c\/li\u003e\n  \u003cli\u003eRoloc TSM Type S attaching system allows tool-free disc changes\u003c\/li\u003e\n  \u003cli\u003e20,000 RPM maximum speed rating for use with standard right-angle grinders\u003c\/li\u003e\n  \u003cli\u003e3-inch diameter fits compact grinders and die grinders in tight work areas\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with Roloc TSM Type S quick-change mandrels and grinders designed to accept Type S attaching system discs at 3 inches in diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by threading the disc button onto a compatible Type S Roloc TSM mandrel until it seats securely. Always confirm the grinder or die grinder is powered off and disconnected from its power source before changing discs. Verify that the tool RPM rating meets or exceeds the disc maximum of 20,000 RPM before operation. Use appropriate eye protection, hearing protection, and gloves in accordance with applicable safety standards when operating abrasive discs.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Polyester Cloth\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Weight\u003c\/strong\u003e: X\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 20,000\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttaching System\u003c\/strong\u003e: Type S (Roloc TSM)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Maroon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eButton Color\u003c\/strong\u003e: Silver\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 947A\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: 0.01 pounds\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: 7100076930\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51716383834418,"sku":"7100076930","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/30b13f6c04343f4b942907a52ae090c1.jpg?v=1788525250","url":"https:\/\/voomisupply.com\/products\/3m-7100076930-quick-change-disc-80-grit-3-in-ceramic-roloc-tsm","provider":"Voomi Supply","version":"1.0","type":"link"}
