Part of the 947A Series, it features a Type S attachment system for fast, tool-free disc swaps on compatible rotary tools and right-angle grinders. The disc is constructed on a polyester cloth backing with an X-weight rating, delivering durability under aggressive grinding conditions. At 120 grit, it falls in the fine grade range, making it suitable for blending, deburring, and light stock removal. A licensed tradesperson or skilled fabricator would typically deploy this disc for weld prep, surface conditioning, and finishing passes.\u003c\/p\u003e\u003cp\u003eThis disc is sized at 1.5 inches in diameter and rated for a maximum of 30,000 RPM, making it well suited for use with small-diameter rotary tools and die grinders in tight-access applications. Common use scenarios include aerospace sheet metal work, automotive body prep, and general metal fabrication where a fine ceramic abrasive is needed on confined surfaces. The Type S button attachment simplifies changeovers when cycling through multiple grits in a single work session.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e120 grit fine-grade ceramic abrasive for blending and light stock removal\u003c\/li\u003e\n\u003cli\u003eType S quick-change attachment system for fast, tool-free disc swaps\u003c\/li\u003e\n\u003cli\u003ePolyester cloth backing with X-weight rating for durability under load\u003c\/li\u003e\n\u003cli\u003e30,000 RPM maximum speed rating for high-speed rotary tool compatibility\u003c\/li\u003e\n\u003cli\u003eCompact 1.5-inch diameter for access in confined work areas\u003c\/li\u003e\n\u003cli\u003e947A Series construction with maroon disc color and white button\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Type S quick-change rotary tool holders and right-angle die grinders that accept 1.5-inch quick-change discs.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and disc changes should be performed with the tool fully powered off and unplugged or with the air supply disconnected before handling. Verify the tool spindle speed does not exceed the 30,000 RPM disc rating prior to operation. A Type S mandrel or holder is required; do not attempt to mount this disc on incompatible attachment systems. Always use appropriate eye protection and follow applicable ANSI B11 and OSHA 1910 abrasive wheel safety guidelines.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 120\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Fine\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\u003eAttaching System\u003c\/strong\u003e: Type S\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: 30,000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 947A\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: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 7100076936\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51692813091122,"sku":"7100076936","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1db5af1d0418dabf19f22dc4e3e0aa58.jpg?v=1788303335","url":"https:\/\/voomisupply.com\/products\/3m-7100076936-quick-change-disc-120-grit-ceramic-1-5-in","provider":"Voomi Supply","version":"1.0","type":"link"}
