Built on an X-weight cloth backing, this 18-inch diameter disc uses aluminum oxide abrasive at 80 grit for fast, aggressive cutting across a wide range of surfaces. A resin bond system locks the abrasive grains in place and dissipates heat to extend disc life. The PSA backing adheres firmly to compatible backup pads or steel platens and releases cleanly for fast changeovers, reducing downtime during production runs. Fabricators, metalworkers, and finishing technicians typically install and operate this disc.\u003c\/p\u003e\u003cp\u003eThis disc is suited for both wet and dry sanding applications on metal, wood, composites, and similar materials. The 18-inch diameter and 80-grit aluminum oxide construction make it appropriate for wide-surface stock removal, weld blending, and intermediate finishing steps on large flat or near-flat workpieces. The 14-inch arbor hole accommodates compatible large-diameter disc machines and rotary platens found in industrial production and shop environments. Minimum order quantity is 10 discs per purchase.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePressure-sensitive adhesive backing adheres to backup pads or steel platens and allows clean, fast removal for quick disc replacement\u003c\/li\u003e\n\u003cli\u003eX-weight cloth backing resists tearing and edge wear during aggressive material removal\u003c\/li\u003e\n\u003cli\u003eAluminum oxide abrasive delivers fast cut rates and long service life across multiple surface types\u003c\/li\u003e\n\u003cli\u003eResin bond protects against heat damage, extending overall disc life\u003c\/li\u003e\n\u003cli\u003eSuitable for both wet and dry sanding applications\u003c\/li\u003e\n\u003cli\u003e18-inch diameter with 14-inch arbor hole fits large-diameter disc machines and rotary platens\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with large-diameter disc machines, rotary platens, and backup pads that accept an 18-inch PSA-mount sanding disc with a 14-inch arbor hole.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDisc installation and replacement should be performed by qualified fabricators or machine operators familiar with large-diameter disc equipment. Power down and de-energize the machine fully before mounting or removing the disc. Ensure the backup pad or steel platen surface is clean and free of debris before applying the PSA backing to achieve proper adhesion. Follow the equipment manufacturer's operating guidelines and applicable workplace safety standards when running abrasive discs at rated speeds.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Size\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Weight\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\u003eApplication\u003c\/strong\u003e: Wet or Dry\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.64 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 7000118891\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51345963221298,"sku":"7000118891","price":256.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310535034.jpg?v=1782067701","url":"https:\/\/voomisupply.com\/products\/3m-7000118891-psa-cloth-sanding-disc-80-grit-18-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
