Built around 3M Precision Shaped Grain ceramic abrasive technology, the disc delivers significantly higher cut rates and longer service life than conventional aluminum oxide or zirconia fibre discs. The stiff vulcanized fibre backing combined with a strong resin bond resists tearing under aggressive grinding pressure. At 4 inches in diameter and 36 grit, this disc is sized for angle grinders used in heavy-duty weld grinding, beveling, edge chamfering, and surface blending operations in fabrication and maintenance environments.\u003c\/p\u003e\u003cp\u003eThis disc is suited for professional metalworking applications including structural steel fabrication, pipe fitting, and heavy equipment repair. Typical use cases include weld bead removal, joint preparation, and surface conditioning on carbon steel workpieces. The 36-grit designation makes it appropriate for aggressive stock removal rather than finish work. Compatible with standard 3M disc pad face plates and hubs, which are sold separately. Minimum order quantity for this SKU is 100 discs per order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3M Precision Shaped Grain ceramic abrasive delivers higher cut rates per disc than conventional abrasive minerals\u003c\/li\u003e\n\u003cli\u003eEngineered for rapid stock removal on carbon steel, including weld grinding, beveling, and edge chamfering\u003c\/li\u003e\n\u003cli\u003eStiff fibre backing and strong resin bond provide tear resistance under sustained grinding pressure\u003c\/li\u003e\n\u003cli\u003eLong-lasting abrasive mineral reduces disc change frequency and lowers 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.

Ensure the grinder is unplugged or the air supply is disconnected before mounting or changing discs. Inspect the disc for cracks or damage before each use and never operate a damaged disc. Follow ANSI B7.1 and applicable shop safety standards for abrasive wheel use, including proper RPM rating verification before 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: 36\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: 4.134 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: 051125872787\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: 7100104929\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51342782431538,"sku":"7100104929","price":429.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310530327.jpg?v=1782006449","url":"https:\/\/voomisupply.com\/products\/3m-7100104929-ceramic-fibre-disc-4-inch-36-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
