Built on a stiff fiber backing with a strong resin bond, this 4-inch diameter disc uses 3M Precision Shaped Grain ceramic abrasive at 60 grit. Licensed HVAC, metalworking, and fabrication professionals reach for this disc when speed of cut and disc longevity both matter. The shaped ceramic grain cuts aggressively and fractures in a controlled way, exposing fresh cutting edges throughout the life of the disc rather than glazing over like conventional abrasive minerals.\u003c\/p\u003e\n\u003cp\u003eThis disc is suited to heavy industrial and shop fabrication tasks where conventional fiber discs fall short. Primary applications include weld removal, weld blending, bevel grinding, edge chamfering, and surface finish refinement on carbon steel workpieces. The combination of high cut rate and extended disc life makes it practical for production grinding environments where downtime from frequent disc changes adds up. It mounts to compatible 3M disc pad face plates and hubs, sold separately.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3M Precision Shaped Grain ceramic abrasive delivers higher cut rates and longer life than conventional abrasive minerals\u003c\/li\u003e\n  \u003cli\u003e4-inch diameter at 60 grit targets aggressive stock removal and weld grinding on carbon steel\u003c\/li\u003e\n  \u003cli\u003eStiff fiber backing and strong resin bond resist tearing under heavy load\u003c\/li\u003e\n  \u003cli\u003eControlled grain fracture exposes fresh cutting edges throughout disc life, reducing cost per part\u003c\/li\u003e\n  \u003cli\u003eSuited for weld removal, beveling, edge chamfering, and blending operations\u003c\/li\u003e\n  \u003cli\u003eCompatible with 3M disc pad face plates and hubs, sold separately\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with 3M disc pad face plates and hubs sold separately.

Ensure the grinder is fully powered down and unplugged before mounting or removing the disc. Verify that the disc pad face plate and hub are rated for the disc diameter and the grinder's maximum RPM before operation. Always use appropriate personal protective equipment including eye protection, gloves, and hearing protection when operating angle grinders with fiber discs.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 60\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: Fiber\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.434 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 11.21 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: 051125872794\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: 7100104873\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51345464820018,"sku":"7100104873","price":386.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310530326.jpg?v=1782059089","url":"https:\/\/voomisupply.com\/products\/3m-7100104873-ceramic-fibre-disc-4-in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
