Built on a durable polyester backing and loaded with 3M Precision-Shaped Grain, this 4.5-inch, 80-grit disc delivers a fast, consistent cut rate across a range of ferrous and non-ferrous metals. As the individual flaps wear, they break down to expose fresh abrasive mineral, maintaining cut performance throughout the life of the disc. Licensed tradespeople and fabricators use it for jobs where both material removal speed and surface finish quality matter.\u003c\/p\u003e\u003cp\u003eThis disc is suited for beveling, weld removal, and edge deburring on structural steel, stainless, and similar metals. The Type 29 conical profile pairs with right-angle grinders, giving the operator better contact angle control on flat and contoured workpieces. The polyester backing handles high unit pressure without delaminating, making it appropriate for production fabrication environments as well as field repair work. Its design reduces the risk of gouging compared to bonded wheels and fiber discs, which is useful when finish quality is a requirement alongside material removal.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3M Precision-Shaped Grain delivers fast, consistent cut rate for the life of the disc\u003c\/li\u003e\n\u003cli\u003eDurable polyester backing withstands high unit pressure applications\u003c\/li\u003e\n\u003cli\u003eIndividual flaps break down progressively, exposing fresh abrasive mineral\u003c\/li\u003e\n\u003cli\u003eType 29 right-angle profile improves contact on flat and contoured surfaces\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 is a requirement alongside material removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard right-angle grinders accepting 4.5-inch Type 29 flap discs.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eMounting and disc changes must be performed with the grinder unplugged or the power source locked out. Verify that the grinder RPM rating meets or exceeds the maximum rated speed of the disc before operation. Eye protection, gloves, and appropriate face shielding are required during use. Inspect the disc for damage before each use and discard any disc showing delamination, tears, or visible damage to the backing.\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 Weight\u003c\/strong\u003e: 2.89 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 8.88 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 5.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 6.13 inches\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: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 076308644203\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: 7100104876\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51343313731890,"sku":"7100104876","price":127.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310535973.jpg?v=1782019985","url":"https:\/\/voomisupply.com\/products\/3m-7100104876-flap-disc-80-grit-4-5-inch-type-29","provider":"Voomi Supply","version":"1.0","type":"link"}
