The wheel measures 8 inches in diameter with a 3-inch arbor bore and features a soft, conformable construction that keeps abrasive media in continuous contact with the workpiece surface. At 3.149 pounds, it is built for bench grinder and automated fixture use. The layered, unitized structure resists smearing and minimizes heat buildup, making it suitable for work on heat-sensitive substrates. Machinists, fabricators, and finishing technicians typically deploy this wheel in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for edge deburring, blending, and finish work on ferrous and non-ferrous metal alloys as well as many plastics and composites. It performs in both manual bench-grinder setups and robotic or automated processing cells, where its conformability allows consistent contact on complex or contoured part geometries. It is available in a range of densities and grades, from soft and conformable at density 2 up to hard and aggressive at density 8, so the correct unit can be matched to the cut rate and surface finish requirement of the application.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e8-inch diameter with 3-inch arbor bore for standard bench grinder and spindle mounting\u003c\/li\u003e\n  \u003cli\u003eConformable, layered unitized construction maintains abrasive contact on complex and contoured part profiles\u003c\/li\u003e\n  \u003cli\u003eOperates in clockwise or counterclockwise rotation without performance loss\u003c\/li\u003e\n  \u003cli\u003eMinimizes heat buildup to protect heat-sensitive metals, plastics, and composites\u003c\/li\u003e\n  \u003cli\u003eResists smearing for cleaner cut surfaces and reduced prep time between operations\u003c\/li\u003e\n  \u003cli\u003eWheel edge can be dressed for targeted deburring, finishing, and polishing tasks\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and standard production wheel for bench grinders and automated finishing spindles accepting a 3-inch arbor bore and an 8-inch diameter unitized wheel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMounting should be performed by a qualified machinist or tooling technician with the grinder or spindle fully de-energized and locked out per OSHA lockout\/tagout procedures. Verify that the machine spindle speed rating does not exceed the maximum rated RPM of the wheel before operation. Inspect the wheel for damage or separation before each use and do not operate a damaged unitized wheel. Use appropriate flanges and hardware as specified by the machine manufacturer to ensure secure seating on the arbor.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Bore\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.149 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 8.6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 8.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 2.5 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: 048011186011\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: 7000120921\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344601022770,"sku":"7000120921","price":492.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310522163.jpg?v=1782037539","url":"https:\/\/voomisupply.com\/products\/3m-7000120921-scotch-brite-exl-unitized-wheel-8-in-3-in-arbor","provider":"Voomi Supply","version":"1.0","type":"link"}
