Built on an X-weight cloth backing, this 12-inch disc uses aluminum oxide abrasive at 50 grit to deliver coarse-grade cutting action suitable for weld blending, surface prep, and stock removal tasks. The flexible backing conforms to mild surface irregularities, maintaining consistent abrasive contact across the workpiece. Licensed tradespeople and shop professionals working in metal fabrication, HVAC sheet metal work, and general industrial maintenance will find this disc well-suited for high-load grinding applications where durability and cut rate matter.\u003c\/p\u003e\u003cp\u003eThis disc is designed for use on bench top motors and random orbital sanders. The 12-inch diameter and PSA mount make it a direct fit for compatible platens and backup pads in shop and field environments. The coarse 50-grit aluminum oxide construction handles initial surface conditioning, rust and scale removal, and weld seam blending on steel, aluminum, and other common trade materials. No vacuum holes are included, making it suited for solid-platen setups. The maroon disc color is consistent with the 3M 348D series designation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e12-inch diameter PSA disc for bench top motors and random orbital sanders\u003c\/li\u003e\n\u003cli\u003e50-grit aluminum oxide abrasive provides coarse-grade, high-rate stock removal\u003c\/li\u003e\n\u003cli\u003eX-weight cloth backing delivers durability under heavy grinding loads\u003c\/li\u003e\n\u003cli\u003eFlexible construction conforms to mild surface contours for consistent contact\u003c\/li\u003e\n\u003cli\u003eNo vacuum holes — designed for solid-platen backup pad use\u003c\/li\u003e\n\u003cli\u003ePart of the 3M 348D series\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with bench top motors and random orbital sanders equipped with 12-inch PSA backup pads or platens.

Ensure the machine is powered down and unplugged before mounting or removing the disc. Clean the backup pad surface before applying the PSA disc to ensure full adhesion and prevent disc slippage during operation. Always verify that the disc speed rating is equal to or greater than the maximum RPM of the host machine before use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 12 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\u003eDisc Color\u003c\/strong\u003e: Maroon\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\u003eMachine Compatibility\u003c\/strong\u003e: Bench Top Motors, Random Orbital Sanders\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 348D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.9 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 7000118897\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51698431000882,"sku":"7000118897","price":19.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2262e6b0379b4feea4f78d0486026213_7fc30b5e-1dd8-466d-8c39-1ffbb29cae7c.jpg?v=1788362750","url":"https:\/\/voomisupply.com\/products\/3m-7000118897-psa-disc-12-in-50-grit-aluminum-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
