It uses aluminum oxide grain on an A-weight paper backing, delivering consistent cut and surface finish at 320 extra-fine grit. The disc measures 5 inches in diameter and mounts directly to PSA-compatible backup pads without fasteners or hook-and-loop hardware. Each pack contains 175 discs. This product is part of the 3M 216U series and is designed for use by finishing tradespeople, auto body technicians, woodworkers, and surface prep professionals who need repeatable results across high-volume sanding work.\u003c\/p\u003e\u003cp\u003eThis disc is suited for fine finish sanding on wood, metal, primers, and composite surfaces in both shop and field environments. At 320 grit, it is used in final preparation stages before topcoat application, between-coat scuffing, or light defect removal on previously sanded surfaces. The flexible paper backing conforms to moderate contours, making it useful on slightly curved panels or furniture components. Compatible with random orbital sanders that accept 5-inch PSA discs. No vacuum holes are present, so this disc is intended for use without dust extraction through the pad.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e320 extra-fine grit aluminum oxide abrasive for consistent finish-stage cutting\u003c\/li\u003e\n\u003cli\u003ePressure-sensitive adhesive backing for fast, tool-free disc changes\u003c\/li\u003e\n\u003cli\u003eA-weight paper backing provides flexibility for light contour sanding\u003c\/li\u003e\n\u003cli\u003eNo vacuum holes — suited for solid backup pads without dust extraction ports\u003c\/li\u003e\n\u003cli\u003eGold disc color aids visibility during use and helps identify grit stage\u003c\/li\u003e\n\u003cli\u003e175 discs per pack supports high-volume production workflows\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with random orbital sanders that accept 5-inch PSA backup pads.

Power down the sander and disconnect it from power before mounting or removing discs. Apply firm, even pressure across the disc face when attaching to the backup pad to ensure full adhesive contact. Discard discs that show signs of loading, tearing, or loss of adhesion to maintain consistent surface finish quality.\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: 320\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Extra 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-Weight\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\u003eSeries\u003c\/strong\u003e: 216U\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity per Pack\u003c\/strong\u003e: 175 discs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 1.25 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: 7000118110\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51690638475570,"sku":"7000118110","price":181.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2be779ad91db157b35f3af5fb133c4e2_19c5c94b-cd37-4459-bbee-0cc27ef2e4ff.jpg?v=1788273118","url":"https:\/\/voomisupply.com\/products\/3m-7000118110-psa-disc-320-grit-5-in-aluminum-oxide-175-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
