The wheel uses aluminum oxide (AO) abrasive mineral bonded into a soft, conformable non-woven construction that maintains consistent surface contact throughout the wheel's life. At 4 inches in diameter with a 3\/8 inch arbor hole, it mounts directly to bench grinders, pedestal grinders, and angle grinder arbors. Machinists, fabricators, and finishing technicians use this wheel to achieve uniform edge and surface finishes without introducing excessive heat into the workpiece.\u003c\/p\u003e\u003cp\u003eThis unitized wheel is suited for both manual and automated finishing operations, including robotic processing where consistent conformability is required. The layered construction allows the wheel to work on complex geometries and contoured edges. It is appropriate for use on stainless steel, carbon steel, aluminum, titanium, and many engineering plastics. Applications include edge deburring after machining, pre-polish surface preparation, and light stock removal on heat-sensitive materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSoft, conformable non-woven construction stays in contact with complex and contoured part geometries\u003c\/li\u003e\n\u003cli\u003eAluminum oxide abrasive mineral delivers consistent cut on metal alloys, plastics, and composites\u003c\/li\u003e\n\u003cli\u003eLayered unitized build supports both clockwise and counterclockwise rotation\u003c\/li\u003e\n\u003cli\u003eMinimizes heat buildup, reducing thermal impact on heat-sensitive workpiece materials\u003c\/li\u003e\n\u003cli\u003eResists smearing for cleaner finished surfaces and reduced rework\u003c\/li\u003e\n\u003cli\u003eWheel edge can be dressed to maintain profile for precision deburring and polishing work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on bench grinders, pedestal grinders, and arbor-driven finishing equipment 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 machinist or finishing technician. Disengage and lock out all power to the grinder before mounting or removing the wheel. Confirm arbor shaft diameter matches the 3\/8 inch bore before seating the wheel, and verify that the grinder RPM rating does not exceed the wheel's maximum rated speed. Always dress the wheel face with an appropriate dressing tool before initial use to expose fresh abrasive and true the running surface.\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 Hole Diameter\u003c\/strong\u003e: 3\/8 inch\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 non-woven\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 00048011280226\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: 7000028519\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51346876530994,"sku":"7000028519","price":392.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310522846.jpg?v=1782093221","url":"https:\/\/voomisupply.com\/products\/3m-7000028519-scotch-brite-exl-unitized-wheel-4-in-ao","provider":"Voomi Supply","version":"1.0","type":"link"}
