The wheel measures 4 inches in diameter with a 3\/8 inch arbor bore and is constructed from aluminum oxide abrasive mineral bonded into a layered, unitized nylon web. The soft, conformable construction keeps the abrasive in continuous contact with irregular or complex part geometries, making it well suited for both manual bench grinding and automated robotic processing. Weighing 0.2 pounds, the wheel is lightweight and easy to handle during setup or changeover.\u003c\/p\u003e\u003cp\u003eThis wheel is used in metalworking, fabrication, and finishing operations across light industrial and manufacturing environments. Typical applications include edge deburring on cut sheet metal, blending weld seams, surface conditioning prior to coating, and finishing of aluminum, stainless steel, and other metal alloys. It also performs on many plastic and composite substrates without smearing or glazing the surface. The wheel is appropriate for use by machinists, fabricators, and toolroom technicians working with bench grinders or compatible right-angle tools.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eLayered unitized construction runs clockwise or counterclockwise without performance loss\u003c\/li\u003e\n\u003cli\u003eConformable nylon web keeps abrasive in contact with complex or irregular part shapes\u003c\/li\u003e\n\u003cli\u003eAluminum oxide mineral provides consistent cut on metal alloys, plastics, and composites\u003c\/li\u003e\n\u003cli\u003eMinimizes heat buildup, reducing risk of damage to heat-sensitive base materials\u003c\/li\u003e\n\u003cli\u003eResists smearing for cleaner finished surfaces with less prep work between passes\u003c\/li\u003e\n\u003cli\u003eWheel edge can be dressed to restore cutting action for deburring and polishing tasks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use unitized abrasive wheel for bench grinders and right-angle tools accepting a 3\/8 inch arbor with a 4 inch diameter wheel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified technician familiar with abrasive wheel safety per ANSI B7.1 guidelines. Power down and lock out the grinder or tool before mounting or removing the wheel. Confirm the tool spindle speed rating meets or exceeds the wheel maximum RPM before operation. Inspect the wheel for damage before each use and do not operate a cracked or deformed wheel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Size\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Mineral\u003c\/strong\u003e: Aluminum Oxide (AO)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e: Unitized layered nylon web\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 5.7 x 5.7 x 6 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: 00048011185897\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: 7000120920\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51345844338994,"sku":"7000120920","price":506.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310522200.jpg?v=1782064387","url":"https:\/\/voomisupply.com\/products\/3m-7000120920-unitized-abrasive-wheel-4-in-aluminum-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
