Built on a durable polyester backing, it incorporates 3M Precision-Shaped Grain that fractures as the disc wears, continuously exposing fresh cutting mineral. The result is a consistent, fast cut rate maintained throughout the life of the disc. At 4.5 inches in diameter and 40 grit, this disc is suited for aggressive stock removal while still delivering a surface finish acceptable for appearance-critical work. It is designed for use with right angle grinders and is a practical choice for fabrication and maintenance trades.\u003c\/p\u003e\u003cp\u003eThis flap disc is used in metal fabrication, structural steel work, welding shops, and industrial maintenance environments. Primary applications include beveling, weld removal, and edge deburring on a variety of ferrous and non-ferrous metals. The Type 27 flat profile is appropriate for surface grinding and blending passes. Because flap discs flex slightly during use, they carry a lower risk of gouging the workpiece compared to bonded abrasive wheels or fiber discs, making them a reliable option when surface finish matters.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3M Precision-Shaped Grain delivers a fast, consistent cut rate throughout disc life\u003c\/li\u003e\n\u003cli\u003eDurable polyester backing handles high unit pressure without delaminating\u003c\/li\u003e\n\u003cli\u003eIndividual flaps break down progressively, exposing fresh abrasive as the disc wears\u003c\/li\u003e\n\u003cli\u003eLower gouging risk compared to bonded wheels and fiber discs\u003c\/li\u003e\n\u003cli\u003eType 27 right angle profile suitable for surface grinding and blending\u003c\/li\u003e\n\u003cli\u003e40 grit provides aggressive stock removal with an acceptable finish for appearance-sensitive applications\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 27 flap discs.

Verify the grinder spindle speed rating meets or exceeds the maximum RPM rating of the disc before mounting. Inspect the disc for damage before each use and discard any disc that shows tears, separation, or deformation. Eye protection, 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\u003eDiameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 40\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Type\u003c\/strong\u003e: Type 27 (Right Angle)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Polyester\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\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\u003eWeight\u003c\/strong\u003e: 3.05 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\u003eUPC\u003c\/strong\u003e: 076308644067\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: 7100104912\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51343084224818,"sku":"7100104912","price":127.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310535906.jpg?v=1782016087","url":"https:\/\/voomisupply.com\/products\/3m-7100104912-flap-disc-4-5-inch-40-grit-type-27","provider":"Voomi Supply","version":"1.0","type":"link"}
