Manufactured in the 426U series, this disc measures 5 inches in diameter and cuts with 320-grit silicon carbide abrasive, placing it in the extra fine grade. The paper backing is A-weight, providing a flexible, conformable feel that follows contours and reduces swirl marks during finish passes. The gray disc has no vacuum holes, so it is suited for sanders without dust-port attachments or for wet sanding setups. Each package contains 175 discs.\u003c\/p\u003e\n\u003cp\u003eThis disc is a practical choice for sanding wood, painted surfaces, metal, fiberglass, or composite materials where a fine, controlled cut is needed before finishing or sealing. The 320-grit silicon carbide formulation is well suited to final prep sanding between coats of primer or paint, light stock removal on hard substrates, and surface leveling prior to a topcoat. The PSA backing allows quick, repeatable disc changes on compatible 5-inch random orbital sanders without the need for hook-and-loop pads.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e320-grit silicon carbide abrasive for extra fine material removal and finish prep\u003c\/li\u003e\n  \u003cli\u003e5-inch diameter PSA backing for fast, secure adhesion to sanding pads\u003c\/li\u003e\n  \u003cli\u003eA-weight paper backing provides flexibility and conformability on contoured surfaces\u003c\/li\u003e\n  \u003cli\u003eNo vacuum holes — compatible with solid-pad random orbital sanders\u003c\/li\u003e\n  \u003cli\u003e175 discs per package for extended production use\u003c\/li\u003e\n  \u003cli\u003e3M 426U series construction for consistent cut rate across the disc life\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 5-inch random orbital sanders equipped with PSA sanding pads. No vacuum holes are present, so this disc is not intended for sanders that require hole-pattern dust extraction through the pad.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eEnsure the sanding pad surface is clean and free of adhesive residue before applying each new disc to maintain full contact and prevent premature release. Press the disc firmly onto the pad from the center outward to eliminate air pockets. Worn or contaminated PSA pads should be replaced before applying fresh discs, as reduced adhesion can cause the disc to separate during operation. Dispose of used discs in accordance with local regulations if sanding materials that may contain hazardous coatings.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: Silicon Carbide\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\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: Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 426U\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMachine Compatibility\u003c\/strong\u003e: Random Orbital Sanders\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity Per Package\u003c\/strong\u003e: 175 discs\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 1.16 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 11 inches x 9.5 inches x 7 inches\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: 7000119240\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51716308599090,"sku":"7000119240","price":107.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd8da5dc65c0238bdf5f2c9e9bee6959.jpg?v=1788524160","url":"https:\/\/voomisupply.com\/products\/3m-7000119240-psa-disc-320-grit-5-inches-175-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
