Built with a ceramic aluminum oxide abrasive, this disc delivers consistent cut rate and durability on metal, wood, and composite surfaces. It features an F-weight paper backing, which provides a balance of flexibility and support suited to contoured and flat workpieces. At 80 grit, it falls in the medium grade range, making it effective for stock removal, blending, and scratch refinement. This disc is installed by metal fabricators, woodworkers, automotive technicians, and maintenance tradespeople using random orbital sanders.\u003c\/p\u003e\u003cp\u003eThis disc is intended for use with random orbital sanders in both shop and field applications. The pressure-sensitive adhesive backing allows for fast disc changes directly onto PSA-compatible backing pads without the need for hook-and-loop hardware. The flexible paper construction conforms to moderate surface contours. Each package contains 100 discs, making it appropriate for production environments or contractors managing high-volume sanding operations. The disc measures 5 inches in diameter and does not include vacuum holes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic aluminum oxide abrasive for extended cut life and consistent performance\u003c\/li\u003e\n\u003cli\u003e80 grit medium grade suited for stock removal and surface blending\u003c\/li\u003e\n\u003cli\u003eF-weight paper backing balances flexibility with structural support\u003c\/li\u003e\n\u003cli\u003ePressure-sensitive adhesive backing for quick mounting on PSA sanding pads\u003c\/li\u003e\n\u003cli\u003eNo vacuum holes — compatible with solid PSA backing pads\u003c\/li\u003e\n\u003cli\u003e100 discs per package for production and high-volume use\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with random orbital sanders equipped with 5-inch PSA (pressure-sensitive adhesive) backing pads.

Align the disc flat against the PSA backing pad and press firmly from the center outward to ensure full adhesion and prevent edge lifting during use. Worn or contaminated backing pads reduce disc adhesion and should be replaced before installing a new disc. Follow applicable workplace safety standards for eye and respiratory protection when performing abrasive operations.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Paper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Weight\u003c\/strong\u003e: F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Red\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVacuum Holes\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMachine Compatibility\u003c\/strong\u003e: Random Orbital Sanders\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 763U\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Discs\u003c\/strong\u003e: 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 2.63 pounds\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: 7100078003\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51693039190322,"sku":"7100078003","price":213.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/caae37ff2650c186f8d7edc45f5cae73.jpg?v=1788306552","url":"https:\/\/voomisupply.com\/products\/3m-7100078003-psa-disc-80-grit-ceramic-5-inches-100-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
