Built with aluminum oxide abrasive on a flexible cloth backing, this disc delivers coarse 40-grit cutting action suitable for grinding, shaping, and surface preparation. The disc measures 8 inches in diameter and weighs 0.02 pounds. The PSA mount allows fast disc changes on compatible sanders without additional hardware. The flexible cloth backing conforms slightly to the workpiece, maintaining consistent contact across the cut zone. Fabricators, machinists, and metalworkers are the primary installers and users of this consumable.\u003c\/p\u003e\n\u003cp\u003eThis disc is suited for use in metal fabrication shops, woodworking operations, and general manufacturing environments where coarse stock removal is required. The 40-grit aluminum oxide construction handles initial surface prep, weld spatter removal, scale removal, and aggressive shaping tasks. It is a single-disc unit sold individually. The flexible backing makes it usable on both rigid and slightly contoured flat surfaces. No vacuum holes are included, so it is intended for use on non-vacuum PSA disc sanders or backing plates.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e40-grit aluminum oxide abrasive for fast, coarse material removal\u003c\/li\u003e\n  \u003cli\u003e8-inch diameter fits standard PSA backing plates of the same size\u003c\/li\u003e\n  \u003cli\u003eFlexible cloth backing conforms to work surface and resists tearing\u003c\/li\u003e\n  \u003cli\u003ePressure-sensitive adhesive mount for tool-free disc changes\u003c\/li\u003e\n  \u003cli\u003eNo vacuum holes — compatible with solid PSA backing plates\u003c\/li\u003e\n  \u003cli\u003eBlack disc color aids in visual wear monitoring during use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or consumable fitment for 8-inch PSA disc sanders and backing plates requiring a cloth-backed, non-vacuum abrasive disc.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by the operator — no licensed trade is required for disc changes. Power down and unplug the sander or disconnect compressed air before swapping discs. Peel the release liner from the PSA backing and center the disc firmly onto a clean, dry backing plate before applying pressure across the full face to seat the adhesive. Discard discs showing visible loading, glazing, or torn backing material, as degraded abrasives increase heat buildup and reduce cut quality.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Cloth\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlexible\u003c\/strong\u003e: Yes\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: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Pressure-Sensitive Adhesive (PSA)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: MERIT ABRASIVES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 08834172088\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT","offers":[{"title":"Default Title","offer_id":51558121210162,"sku":"08834172088","price":408.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/66a3fdea24a76fc0b122047ae57bc73d.jpg?v=1786404001","url":"https:\/\/voomisupply.com\/products\/merit-abrasives-08834172088-psa-disc-8-in-40-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
