Designated as the 782C, it is engineered for ultra-rapid material removal on carbon steel and similarly demanding ferrous surfaces. The precision shaped ceramic mineral geometry drives higher cut rates and longer disc life compared to conventional aluminium oxide or zirconia fibre discs. A stiff fibre backing and high-strength resin bond system keep the disc stable under aggressive pressure, resisting tearing and deformation during sustained grinding. At 80 grit, it balances aggressive stock removal with reasonable surface finish for pre-weld and post-weld applications. Licensed tradespeople and fabrication shop grinder operators are the primary installers.\u003c\/p\u003e\u003cp\u003eThe 7100104603 is suited to metal fabrication, structural steel work, and maintenance grinding applications where rapid weld removal, beveling, edge chamfering, and surface blending are required. Its 80-grit ceramic construction makes it effective for heavy stock removal on carbon steel plate, pipe, and structural shapes in both shop and field settings. It is sold individually and designed for use with compatible 3M disc pad face plates and hubs, which are sold separately.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3M Precision Shaped Grain ceramic abrasive delivers higher cut rates than conventional fibre discs\u003c\/li\u003e\n\u003cli\u003e80-grit construction balances aggressive stock removal with surface blending capability\u003c\/li\u003e\n\u003cli\u003eStiff fibre backing and strong resin bond resist tearing under sustained load\u003c\/li\u003e\n\u003cli\u003eEffective for weld removal, beveling, edge chamfering, and finish blending on carbon steel\u003c\/li\u003e\n\u003cli\u003eLong-lasting abrasive mineral helps reduce per-part abrasive cost\u003c\/li\u003e\n\u003cli\u003eCompatible with 3M disc pad face plates and hubs (sold separately)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 3M disc pad face plates and hubs sold separately.

Always power down and disconnect the grinder before changing discs. Verify the grinder's maximum RPM rating meets or exceeds the disc's rated speed before use, and inspect the disc for cracks or damage prior to each use. Eye protection, a face shield, and appropriate PPE are required during operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Precision Shaped Ceramic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking\u003c\/strong\u003e: Coated Fibre\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 3.234 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 11.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 6.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 6.95 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 051125872800\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: 7100104603\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51343027306802,"sku":"7100104603","price":365.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310530329.jpg?v=1782014269","url":"https:\/\/voomisupply.com\/products\/3m-7100104603-ceramic-fibre-disc-4-inch-80-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
