Part of the 3M 348D series, this disc measures 30 inches in diameter and features 50-grit aluminum oxide abrasive on a coarse-grade, heavyweight X-weight cloth backing. The cloth backing provides durability and flexibility, making it well suited for contoured or irregular surfaces. It mounts via a PSA backing directly to compatible disc pads, eliminating the need for mechanical fasteners. Trade professionals in fabrication, woodworking, metal finishing, and surface prep rely on this disc for high-stock-removal passes on large-format equipment.\u003c\/p\u003e\u003cp\u003eThis disc is intended for use with random orbital sanders that accept 30-inch PSA-style abrasive discs. The 50-grit coarse rating makes it appropriate for initial material removal, leveling uneven surfaces, and preparing substrates before finishing grits are applied. It does not include vacuum holes, so it is best suited for open-face sanding applications where dust extraction through the disc is not required. The flexible cloth construction allows it to conform to slight surface variations without tearing under load.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e30-inch diameter PSA disc for large-format random orbital sanders\u003c\/li\u003e\n\u003cli\u003e50-grit aluminum oxide abrasive for coarse, high-stock-removal cutting action\u003c\/li\u003e\n\u003cli\u003eHeavyweight X-weight cloth backing delivers durability and surface flexibility\u003c\/li\u003e\n\u003cli\u003ePressure-sensitive adhesive mount for fast, tool-free disc changes\u003c\/li\u003e\n\u003cli\u003eNo vacuum holes — suited for open-face sanding operations\u003c\/li\u003e\n\u003cli\u003eMaroon disc color for easy grit identification in the shop\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with random orbital sanders that accept 30-inch PSA abrasive discs.

Power down and disconnect the sander from its power source before removing a spent disc or mounting a new one. Press the PSA disc firmly and evenly onto the backing pad to seat the adhesive fully before resuming operation. Follow applicable shop safety practices, including use of appropriate respiratory protection and eye protection when operating abrasive equipment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 30 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\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\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\u003eDisc Color\u003c\/strong\u003e: Maroon\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: 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 pound\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: 7010511420\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51542139240754,"sku":"7010511420","price":108.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4512daaeb8c0f35100a2514b7d8a8578.jpg?v=1785893323","url":"https:\/\/voomisupply.com\/products\/3m-7010511420-psa-disc-30-in-50-grit-aluminum-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
