The disc features a precision shaped ceramic abrasive grain bonded to a YF-weight polyester cloth backing, which resists tearing and flexing during surface contact. At 80 grit, this disc cuts aggressively enough to remove light weld scale, surface oxidation, and mill finish while leaving a consistent scratch pattern ready for finer finishing steps. Installation requires only a compatible PSA backup pad — no fasteners or clip systems involved. The disc weighs approximately 0.036 pounds and measures 5 inches in diameter.\u003c\/p\u003e\u003cp\u003eThis disc is suited for finishing operations on metal surfaces in residential and light commercial trade environments. HVAC fabricators use PSA discs like this one for deburring duct flanges, cleaning weld seams on sheet metal, and prepping surfaces before sealant or coating application. Plumbers and pipefitters use them on copper and steel pipe ends. The no-vacuum-hole design is appropriate for open-face grinding and finishing where dust extraction through the pad is not required. The maroon disc color and precision shaped ceramic grain indicate a mid-grade finishing tier, optimized for controlled stock removal without aggressive loading.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePrecision shaped ceramic abrasive grain for consistent cut and long disc life\u003c\/li\u003e\n\u003cli\u003e80 grit provides aggressive finishing suitable for weld seam cleanup and surface prep\u003c\/li\u003e\n\u003cli\u003eYF-weight polyester cloth backing resists flex fatigue and tearing under load\u003c\/li\u003e\n\u003cli\u003ePSA (pressure-sensitive adhesive) mount attaches directly to compatible backup pads\u003c\/li\u003e\n\u003cli\u003eNo vacuum holes — designed for open-face finishing without dust extraction ports\u003c\/li\u003e\n\u003cli\u003e5-inch diameter fits standard 5-inch PSA backup pads used across trade applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with any standard 5-inch PSA (pressure-sensitive adhesive) backup pad on right-angle grinders or random orbital sanders configured for PSA-style discs.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by trade technicians, fabricators, or maintenance professionals using a right-angle grinder or orbital sander equipped with a PSA backup pad. Power down and disconnect the tool from its power source before mounting or removing the disc. Align the disc squarely on the backup pad and press firmly across the full surface to ensure full adhesive contact before use. Inspect the disc before each use and discard if the abrasive layer shows separation, tearing, or uneven wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Precision Shaped Ceramic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Polyester Cloth\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Weight\u003c\/strong\u003e: YF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Maroon\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVacuum Holes\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.036 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 7100264052\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51544054268210,"sku":"7100264052","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e18b167b394db7f9ab21355c9e4feda6.jpg?v=1785923356","url":"https:\/\/voomisupply.com\/products\/3m-7100264052-psa-disc-80-grit-5-inch-ceramic","provider":"Voomi Supply","version":"1.0","type":"link"}
