Built with 3M Precision-Shaped Grain bonded to a durable polyester backing, this 4.5-inch, 80-grit Type 29 disc delivers a fast, consistent cut rate across a range of metals while maintaining a smooth surface finish. The disc is engineered for right-angle grinder use and suits trade professionals who need reliable material removal without sacrificing finish quality. Individual flaps progressively break down during use, continuously exposing fresh abrasive grain to sustain cut performance through the life of the disc.\u003c\/p\u003e\u003cp\u003eThis flap disc is well suited for metal fabrication, welding, and mechanical trades where tasks such as beveling, weld removal, and edge deburring are routine. Its Type 29 conical profile allows greater surface contact on flat and contoured workpieces compared to a flat Type 27 disc. The 80-grit cut is positioned in the medium-aggressive range, making it appropriate for stock removal where a workable surface finish is still required. It is sold in a minimum quantity of 10 discs per order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3M Precision-Shaped Grain delivers fast, consistent cut rate on steel, stainless, and other metals\u003c\/li\u003e\n\u003cli\u003eDurable polyester backing withstands high unit pressure during aggressive grinding\u003c\/li\u003e\n\u003cli\u003eIndividual flaps break down progressively, exposing fresh abrasive grain throughout disc life\u003c\/li\u003e\n\u003cli\u003eType 29 right-angle profile increases surface contact on flat and contoured workpieces\u003c\/li\u003e\n\u003cli\u003eLower gouging risk compared to fiber discs and bonded grinding wheels\u003c\/li\u003e\n\u003cli\u003eSuitable for applications where surface finish quality is a priority alongside material removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with right-angle grinders accepting 4.5-inch diameter abrasive flap discs with a standard arbor configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and disc changes must be performed by a qualified operator with the grinder fully powered off and unplugged or locked out per applicable OSHA lockout\/tagout procedures. Verify that the grinder's rated RPM meets or exceeds the maximum RPM marked on the disc before mounting. Inspect the disc for damage before each use and do not operate a disc that shows tears, separation, or delamination of the flaps. Appropriate PPE including eye protection, hearing protection, and gloves is required during operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Type\u003c\/strong\u003e: Type 29 (Right Angle)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Grain\u003c\/strong\u003e: 3M Precision-Shaped Grain\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Polyester\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 7.13 x 5.25 x 5.63 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 3.951 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 076308643930\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: 7100104615\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51343177515314,"sku":"7100104615","price":136.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310535938.jpg?v=1782019161","url":"https:\/\/voomisupply.com\/products\/3m-7100104615-flap-disc-4-5-inch-80-grit-type-29","provider":"Voomi Supply","version":"1.0","type":"link"}
