Built around 3M Precision Shaped Grain abrasive technology, it delivers faster cut rates and longer service life than conventional fibre discs. Rated to 8600 RPM, this disc operates on standard right-angle grinders equipped with compatible quick-change disc pads and hubs. At 80 grit, it strikes a practical balance between aggressive stock removal and surface control, making it well-suited for weld removal, beveling, edge chamfering, and blending operations in fabrication and structural steel work.\u003c\/p\u003e\u003cp\u003eThis disc is intended for professional metalworking applications where consistent cut performance and disc longevity are critical. Typical use cases include weld grinding and blending on carbon steel plate and structural members, edge chamfering prior to fit-up, and surface conditioning in fabrication shops and field welding environments. The stiff fibre backing and strong resin bond maintain disc integrity under the high lateral forces common in heavy grinding passes. Disc pads, face plates, and hubs required for quick-change mounting are sold separately.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3M Precision Shaped Grain abrasive delivers higher cut rates per disc than conventional mineral\u003c\/li\u003e\n\u003cli\u003e80 grit provides aggressive stock removal suited for weld grinding, beveling, and edge chamfering\u003c\/li\u003e\n\u003cli\u003e8600 RPM maximum speed rating supports standard right-angle grinder operation\u003c\/li\u003e\n\u003cli\u003eStiff fibre backing and strong resin bond resist tearing under heavy grinding loads\u003c\/li\u003e\n\u003cli\u003eQuick-change attachment system reduces disc swap time during production work\u003c\/li\u003e\n\u003cli\u003eLong-lasting abrasive mineral lowers cost-per-part compared to standard fibre discs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with 3M disc pad face plates and hubs designed for Quick Change Type discs, sold separately.

Verify that the grinder free-speed RPM does not exceed the 8600 RPM disc rating before mounting. Power down and disconnect the grinder from the power source before changing discs. Confirm the quick-change hub and face plate are properly seated and locked before resuming operation, and always use appropriate eye, face, and hand protection during grinding.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 7 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: 8600 RPM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Precision Shaped Grain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking\u003c\/strong\u003e: Fibre\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment Style\u003c\/strong\u003e: Quick Change\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 10.746 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 21.59 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 8.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 8.95 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 076308896152\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: 7100099274\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51347425689906,"sku":"7100099274","price":587.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310535992.jpg?v=1782104579","url":"https:\/\/voomisupply.com\/products\/3m-7100099274-quick-change-fibre-disc-80-grit-7-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
