Built on an A-weight paper backing with an aluminum oxide abrasive, this disc delivers consistent very fine 180-grit cutting action suited for final prep work, between-coat scuff sanding, and surface smoothing. The gold-colored disc is flexible enough to conform to slightly contoured surfaces while maintaining uniform abrasive contact. Each package contains 175 discs, making it a practical shop-supply quantity for high-volume finishing operations.\u003c\/p\u003e\u003cp\u003eThis disc is intended for use with random orbital sanders equipped for 5-inch PSA-backed abrasives. It is well suited for residential and commercial woodworking, cabinet finishing, automotive bodywork prep, and general metal or composite surface preparation. The PSA backing allows fast disc changes without the need for hook-and-loop fasteners, which is advantageous in production environments where downtime between disc swaps must be minimized. No vacuum holes are included, so this disc is appropriate for sanders used without dust extraction through the pad.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e180-grit aluminum oxide abrasive for very fine surface finishing\u003c\/li\u003e\n\u003cli\u003eA-weight paper backing provides flexibility for moderate contouring\u003c\/li\u003e\n\u003cli\u003ePressure-sensitive adhesive backing for quick, secure attachment to PSA sanding pads\u003c\/li\u003e\n\u003cli\u003eCompatible with 5-inch random orbital sanders\u003c\/li\u003e\n\u003cli\u003eNo vacuum holes — suited for non-dust-extraction pad configurations\u003c\/li\u003e\n\u003cli\u003e175 discs per package for high-volume shop use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 5-inch PSA sanding pads on random orbital sanders.

Before attaching the disc, ensure the sander is powered off and unplugged. Press the disc firmly and evenly onto the PSA pad to achieve full adhesive contact before starting the tool. Discard discs that show signs of loading, tearing, or loss of adhesive bond to avoid uneven surface finish or disc separation during use.\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: 180\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Very Fine\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: Paper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Weight\u003c\/strong\u003e: A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Gold\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\u003eMachine Compatibility\u003c\/strong\u003e: Random Orbital Sanders\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Discs\u003c\/strong\u003e: 175\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 216U\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.22 pounds\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: 7000028128\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51690008576306,"sku":"7000028128","price":176.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2be779ad91db157b35f3af5fb133c4e2.jpg?v=1788265740","url":"https:\/\/voomisupply.com\/products\/3m-7000028128-psa-disc-180-grit-5-in-aluminum-oxide-175pk","provider":"Voomi Supply","version":"1.0","type":"link"}
