Built on an X-weight cloth backing, this 20-inch disc delivers the rigidity and durability required for heavy stock removal and consistent scratch patterns. The aluminum oxide abrasive grain runs at 100 grit, placing it in the fine grade range — suitable for intermediate finishing passes where a uniform surface finish is needed before final steps. The flexible construction allows the disc to conform moderately to contoured surfaces. Licensed trade professionals and production floor operators are the primary users of discs in this format and size.\u003c\/p\u003e\n\u003cp\u003eThis disc is sized at 20 inches in diameter, making it appropriate for large-format bench top motor setups and random orbital sanders capable of accepting 20-inch PSA tooling. It is well suited to metal fabrication shops, industrial surface prep applications, and woodworking operations that require consistent material removal across wide work surfaces. The PSA backing mounts directly to a compatible foam or hard backup pad without the need for hook-and-loop hardware. No vacuum holes are present, so this disc is intended for use on solid backup pads without dust extraction ports.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e20-inch disc diameter for large-format sanding applications\u003c\/li\u003e\n  \u003cli\u003e100 grit aluminum oxide abrasive — fine grade for intermediate finishing\u003c\/li\u003e\n  \u003cli\u003eX-weight cloth backing provides strength and flexibility under load\u003c\/li\u003e\n  \u003cli\u003ePressure-sensitive adhesive mount for fast, secure pad attachment\u003c\/li\u003e\n  \u003cli\u003eNo vacuum holes — designed for solid backup pad use\u003c\/li\u003e\n  \u003cli\u003eCompatible with bench top motors and random orbital sanders\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 abrasive discs with solid backup pads.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMounting and disc changes should be performed with the machine powered off and unplugged. Ensure the backup pad surface is clean and free of debris before pressing the PSA disc firmly into place to achieve full adhesive contact. Verify that the sander or bench motor is rated for the 20-inch disc diameter before use. Worn or glazed discs should be replaced promptly to avoid uneven material removal.\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: 100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Fine\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\u003eVacuum Holes\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Maroon\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.1 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: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7100069134\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51699452281138,"sku":"7100069134","price":45.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fac092b7134367ac4e69462e48dfc781.jpg?v=1788375811","url":"https:\/\/voomisupply.com\/products\/3m-7100069134-psa-abrasive-disc-100-grit-20-inches","provider":"Voomi Supply","version":"1.0","type":"link"}
