Built on an X-weight cloth backing, the disc handles the flex and tension demands of bench-top motors and random orbital sanders without delaminating under load. The abrasive surface uses aluminum oxide grain at 60 grit, a medium grade well-suited for stock removal, weld blending, and surface prep before finishing. At 20 inches in diameter, this disc covers wide work areas in a single pass, reducing cycle time on large workpieces. The maroon disc carries 3M series designation 348D and is sold as a single unit.\u003c\/p\u003e\n\u003cp\u003eThis disc is appropriate for metal fabrication shops, woodworking operations, and industrial surface prep environments where large-format grinding or sanding is performed on bench-top motor setups or random orbital sanders. The PSA mount system allows quick disc changes without mechanical fasteners, keeping downtime low during production runs. No vacuum holes are included, making it best suited for open-face platens or applications where dust extraction is handled separately. It is typically installed and replaced by machinists, fabricators, or skilled tradespeople familiar with large-format abrasive equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e20-inch diameter covers large surface areas in fewer passes\u003c\/li\u003e\n  \u003cli\u003e60-grit aluminum oxide grain delivers consistent medium-grade stock removal\u003c\/li\u003e\n  \u003cli\u003eX-weight cloth backing provides durability and flexibility under load\u003c\/li\u003e\n  \u003cli\u003ePressure-sensitive adhesive mount for fast, tool-free disc changes\u003c\/li\u003e\n  \u003cli\u003eCompatible with bench-top motors and random orbital sanders\u003c\/li\u003e\n  \u003cli\u003eNo vacuum holes — suited for solid-platen use or external dust collection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with bench-top motors and random orbital sanders that accept 20-inch PSA-mount abrasive discs.

Ensure the backing platen is clean and free of adhesive residue so the PSA layer bonds evenly across the full disc face. Peel the liner and apply the disc with firm, even hand pressure from center to edge to eliminate air pockets. Follow the equipment manufacturer guidelines for maximum RPM ratings to confirm this disc size is within the rated operating range of the machine.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 20 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 60\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: Aluminum Oxide\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\u003eAttachment Type\u003c\/strong\u003e: Pressure-Sensitive Adhesive (PSA)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Maroon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVacuum Holes\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlexible\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 348D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.8 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: 7000118885\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51695847964978,"sku":"7000118885","price":46.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4b331a94f84faf822b6caf98f03e8001_8183e5f0-4d37-4318-803a-574fa226f0ae.jpg?v=1788338756","url":"https:\/\/voomisupply.com\/products\/3m-7000118885-psa-abrasive-disc-20-in-60-grit-aluminum-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
