Built on an open-web RC substrate with aluminum oxide abrasive mineral, the disc breaks down under medium pressure to continuously expose fresh fibers and cutting mineral. This self-renewing action maintains a consistent cut rate and resists loading from paint, corrosion, and soft-metal debris. The disc mounts via a quick-change hub for fast swapping between operations. It is identified by its blue color, indicating a very fine grade.\u003c\/p\u003e\n\u003cp\u003eThis disc is suited for flatwork, composite panels, and softer metals such as aluminum. Typical applications include blending, coating removal, light deburring, and surface finishing on flat or mildly contoured parts. The open-web construction conforms to minor surface irregularities and reduces the risk of gouging. It is commonly used in metal fabrication, aerospace prep, and general manufacturing environments where surface condition quality directly affects coating adhesion and finish consistency.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide mineral on RC open-web material delivers good initial and sustained cut rate\u003c\/li\u003e\n  \u003cli\u003eLoad-resistant substrate resists clogging from paint, corrosion, and soft-metal swarf\u003c\/li\u003e\n  \u003cli\u003eOpen-web construction conforms to surface irregularities and minimizes gouging\u003c\/li\u003e\n  \u003cli\u003eQuick-change mounting system allows fast disc swaps without additional tooling\u003c\/li\u003e\n  \u003cli\u003eBlue color coding identifies very fine grade for clear grade selection at the workstation\u003c\/li\u003e\n  \u003cli\u003eSuited for blending, coating removal, finishing, and light deburring on flat surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard quick-change disc holders and right-angle die grinders or finishing tools that accept quick-change RC-style discs.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and disc changes should be performed with the tool powered off and air supply disconnected. Verify that the quick-change mandrel is rated for the tool RPM before mounting the disc. Wear appropriate eye and hand protection during installation and operation. Inspect the disc for damage before each use and replace if the substrate shows tears or excessive wear.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Mineral\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Very Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Blue\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: RC Open-Web\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 4.311 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 23.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 9.63 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 5.13 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 051115369389\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: 7100067989\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346136662322,"sku":"7100067989","price":601.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310529093.jpg?v=1782071752","url":"https:\/\/voomisupply.com\/products\/3m-7100067989-quick-change-disc-1-5-in-aluminum-oxide-very-fine","provider":"Voomi Supply","version":"1.0","type":"link"}
