Built on an X-weight cloth backing, this 3-inch disc handles aggressive stock removal without tearing or edge breakdown. The aluminum oxide abrasive cuts fast and delivers consistent performance across a wide range of surfaces. A resin bond system locks the abrasive in place and dissipates heat to extend disc life. The PSA backing adheres firmly to a backup pad or steel platen and releases cleanly for fast changeovers. Suitable for both wet and dry use.\u003c\/p\u003e\n\u003cp\u003eThis disc is intended for metalworking, woodworking, and composite finishing tasks where aggressive material removal is required. At 40 grit, it is well suited for initial stock removal, weld blending, and surface preparation before finer finishing steps. The 3-inch diameter fits standard PSA backup pads and steel platens used on random orbital sanders and disc grinders. The 10000 RPM maximum speed rating accommodates most right-angle and in-line pneumatic and electric tools running at that speed or below. Professional fabricators, welders, and finishing tradespeople are the primary users.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePressure-sensitive adhesive backing adheres to backup pads or steel platens and releases cleanly for fast disc changes\u003c\/li\u003e\n  \u003cli\u003eX-weight cloth backing resists tearing and edge wear under aggressive load\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive provides fast cut rate and long service life across multiple surface types\u003c\/li\u003e\n  \u003cli\u003eResin bond construction protects abrasive layer from heat damage to extend disc life\u003c\/li\u003e\n  \u003cli\u003eRated for wet and dry applications\u003c\/li\u003e\n  \u003cli\u003eMaximum operating speed of 10000 RPM\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style PSA replacement disc for use with standard 3-inch backup pads and steel platens on pneumatic and electric disc grinders and random orbital sanders rated up to 10000 RPM.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by trained personnel familiar with abrasive tooling and the equipment being used. Before mounting, confirm the tool spindle speed does not exceed the disc maximum speed rating of 10000 RPM. Press the PSA backing firmly onto a clean, dry backup pad or steel platen to ensure full adhesion before operation. Inspect the disc for damage before each use and discard any disc that shows tears, cuts, or delamination.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Speed\u003c\/strong\u003e: 10000 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Type\u003c\/strong\u003e: X-weight Cloth\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment Method\u003c\/strong\u003e: Pressure-Sensitive Adhesive (PSA)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWet\/Dry Rated\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 6.88 x 6.88 x 5.88 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00051144013357\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: 7000118878\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51347475497266,"sku":"7000118878","price":275.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310533828.jpg?v=1782106126","url":"https:\/\/voomisupply.com\/products\/3m-7000118878-psa-cloth-sanding-disc-40-grit-3-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
