Built with a zirconia alumina abrasive grain on an X-weighted cloth backing, this disc delivers consistent cut rate and durability under heavy grinding loads. At 24 inches in diameter and 80 grit, it falls in the medium grade range, making it suited for stock removal, weld blending, and surface prep work where a coarser finish is acceptable. The flexible cloth construction allows it to conform slightly to irregular surfaces while maintaining backing integrity throughout the disc life.\u003c\/p\u003e\n\u003cp\u003eThis disc is used in industrial and fabrication environments where large-diameter PSA discs are required on rotary or random-orbit platen sanders and disc grinders. Typical applications include metal fabrication shops, shipbuilding, structural steel prep, and woodworking operations where high material removal rates on broad surfaces are the priority. The PSA backing mounts directly to a compatible foam or hard backing pad without clips or fasteners, reducing changeover time during production runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eZirconia alumina grain for high cut rate and extended disc life under load\u003c\/li\u003e\n  \u003cli\u003eX-weighted cloth backing provides durability and resistance to tearing during aggressive grinding\u003c\/li\u003e\n  \u003cli\u003e80 grit medium grade balances material removal speed with surface finish control\u003c\/li\u003e\n  \u003cli\u003eFlexible construction allows slight conformability to workpiece contours\u003c\/li\u003e\n  \u003cli\u003ePSA mount for fast, tool-free disc changes on compatible backing pads\u003c\/li\u003e\n  \u003cli\u003eNo vacuum holes  -  suited for solid backing pads without dust extraction ports\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 24-inch PSA-compatible backing pads on rotary disc sanders, platen grinders, and similar large-format abrasive equipment that accept pressure-sensitive adhesive mounted discs.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by abrasive equipment operators and grinding technicians. Before mounting, ensure the backing pad surface is clean and free of adhesive residue from previous discs, as contamination reduces bond strength. Peel the liner from the PSA backing and align the disc carefully to the pad before pressing down firmly from center to edge to eliminate air pockets. Power down and lock out the machine before inspecting or removing a worn disc.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 24 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Zirconia Alumina\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Cloth\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Weight\u003c\/strong\u003e: X\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlexible\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVacuum Holes\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: PSA (Pressure-Sensitive Adhesive)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.7 pounds\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: SUPERIOR ABRASIVES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: A020649\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUPERIOR ABRASIVES","offers":[{"title":"Default Title","offer_id":67916768411954,"sku":"A020649","price":35.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1370c01780d6ad6e31ff5c4683650a9b.jpg?v=1791259183","url":"https:\/\/voomisupply.com\/products\/superior-abrasives-a020649-psa-disc-24-in-80-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
