It is a high-density, hard-construction wheel built for heavy-duty edge deburring and surface polishing on ferrous and non-ferrous metals, including stainless steel and aluminum. The wheel measures 4 inches in diameter with a 1\/4 inch center arbor hole and weighs 1.813 pounds. Its open-web construction resists loading, extending usable service life in demanding production and fabrication environments. Licensed HVAC, plumbing, and metalworking tradespeople who need consistent edge finishing will find this wheel suited to rotary tool and bench-mount applications.\u003c\/p\u003e\u003cp\u003eThis unitized wheel is designed for edge deburring, blending, and polishing operations on metal workpieces in industrial, fabrication, and maintenance settings. The aluminum oxide mineral performs well on carbon steel, stainless steel, and aluminum. Its hard density makes it a step up from 700 Series unitized wheels when tasks require increased edge durability and longer wheel life under continuous use. The wheel runs in both clockwise and counterclockwise directions, giving it added versatility across different tool and machine configurations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHigh-density, hard-construction aluminum oxide wheel engineered for heavy-duty edge deburring and stainless steel polishing\u003c\/li\u003e\n\u003cli\u003eOpen-web structure resists loading for extended abrasive service life\u003c\/li\u003e\n\u003cli\u003eCompatible with both clockwise and counterclockwise rotation for greater tool versatility\u003c\/li\u003e\n\u003cli\u003eAluminum oxide mineral suits ferrous and non-ferrous metals including aluminum and stainless steel\u003c\/li\u003e\n\u003cli\u003eHard density and extra-tough edge durability exceed the performance of 700 Series unitized wheels\u003c\/li\u003e\n\u003cli\u003eAttaches to rotary tools via a unitized wheel mandrel (sold separately)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with rotary tools and machines that accept a 1\/4 inch arbor-mount unitized wheel mandrel.

Ensure the tool or machine is powered down and fully de-energized before mounting or removing the wheel. Confirm the tool spindle speed rating meets or exceeds the maximum RPM rating of the wheel before use. Use only a compatible unitized wheel mandrel sized for the 1\/4 inch arbor hole.\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 Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Mineral\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 800 Series\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Density\u003c\/strong\u003e: Hard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotation Direction\u003c\/strong\u003e: Clockwise and Counterclockwise\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.56 inches x 4.56 inches x 4.31 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.813 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUOM\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 051115356358\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: 7010330321\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51345627808050,"sku":"7010330321","price":253.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310528774.jpg?v=1782061306","url":"https:\/\/voomisupply.com\/products\/3m-7010330321-unitized-abrasive-wheel-4-in-ao-1-4-in-arbor","provider":"Voomi Supply","version":"1.0","type":"link"}
