It measures 4.5 inches in diameter with a 5\/8-11 threaded center hole for direct mounting to standard angle grinders. The 120-grit ceramic abrasive delivers consistent cut rates and extended disc life on ferrous and non-ferrous metals. A plastic backing plate provides rigid support during flat and surface grinding passes. At 0.23 pounds, the disc is lightweight without sacrificing structural integrity under sustained load.\u003c\/p\u003e\n\u003cp\u003eThis flap disc is suited for use in metal fabrication shops, welding operations, and light structural work where surface blending and weld dressing are routine tasks. The Type 27 flat profile is the standard choice when working on flat or slightly contoured stock, tabletops, and structural steel sections. Licensed fabricators, ironworkers, and maintenance welders typically reach for a 120-grit disc when transitioning from heavy material removal to a pre-finish or paint-prep surface condition.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e120-grit ceramic abrasive for consistent cut rate and extended service life\u003c\/li\u003e\n  \u003cli\u003eType 27 flat profile optimized for surface grinding and weld blending\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 threaded hole fits standard angle grinder spindles directly\u003c\/li\u003e\n  \u003cli\u003ePlastic backing plate maintains disc rigidity during flat-surface work\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.23 pounds for reduced operator fatigue during extended use\u003c\/li\u003e\n  \u003cli\u003e4.5-inch diameter fits common 4.5-inch angle grinder guards without modification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 4.5-inch angle grinders equipped with a 5\/8-11 threaded spindle.

Inspect the disc for cracks or damage before mounting and never use a damaged disc. Secure the disc firmly to the grinder spindle using the appropriate flange and ensure the guard is in place before powering on. Always wear appropriate PPE including a face shield, gloves, and hearing protection when operating angle grinders with flap discs.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Hole Size\u003c\/strong\u003e: 5\/8-11 threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlap Disc Type\u003c\/strong\u003e: Type 27\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 120\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Plastic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Threaded Hole\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.23 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 7100243875\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51689161457970,"sku":"7100243875","price":16.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c2d9a11a29491c3399e3cf4853df4344.jpg?v=1788255403","url":"https:\/\/voomisupply.com\/products\/3m-7100243875-flap-disc-120-grit-ceramic-type-27","provider":"Voomi Supply","version":"1.0","type":"link"}
