Built with aluminum oxide abrasive and a soft, conformable construction, this wheel maintains consistent contact with irregular and complex part geometries. It is suited for use on bench grinders, die grinders, and automated or robotic finishing systems. The unitized layered structure allows the wheel to be dressed at the edge for targeted deburring, polishing, and surface prep work across a broad range of materials.\u003c\/p\u003e\n\u003cp\u003eThis wheel is used in fabrication shops, maintenance facilities, and production environments where controlled surface finishing is required. The 1 inch diameter and 3\/16 inch arbor size make it appropriate for small-diameter tooling applications. Its low heat generation makes it well suited for heat-sensitive base materials. Both clockwise and counterclockwise operation are supported, giving flexibility across different machine setups and fixturing configurations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSoft, conformable unitized construction keeps abrasive in contact with complex and irregular part profiles\u003c\/li\u003e\n  \u003cli\u003eWheel edge can be dressed for precise deburring, finishing, and polishing on metals, plastics, and composites\u003c\/li\u003e\n  \u003cli\u003eRuns clockwise or counterclockwise — compatible with varied machine and robotic setups\u003c\/li\u003e\n  \u003cli\u003eMinimizes heat build-up to protect heat-sensitive workpiece materials\u003c\/li\u003e\n  \u003cli\u003eResists smearing for cleaner finished surfaces and reduced prep between passes\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive grain delivers consistent cut across metal alloys and many non-metallic substrates\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a small-diameter unitized finishing wheel for use with bench grinders, die grinders, and robotic finishing systems that accept a 3\/16 inch arbor.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified operator following the machine manufacturer's RPM rating — never exceed the wheel's maximum rated speed. Ensure the spindle is fully stopped and power is disconnected before mounting or changing the wheel. Inspect the wheel for damage before each use and discard any wheel showing cracks, tears, or deformation. Eye protection and appropriate PPE are required during operation per standard abrasive safety practices.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Size\u003c\/strong\u003e: 3\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide (AO)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e: Unitized\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 6.4 x 4.7 x 4.7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 50\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00048011155272\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: 7000021281\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344024895794,"sku":"7000021281","price":324.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310521649.jpg?v=1782027269","url":"https:\/\/voomisupply.com\/products\/3m-7000021281-scotch-brite-exl-unitized-wheel-1-in-ao","provider":"Voomi Supply","version":"1.0","type":"link"}
