Part of the 800 Series, this wheel uses aluminum oxide mineral bonded into a hard-density, open-web construction. The hard density delivers extra edge durability compared to lower-series unitized wheels, making it well suited for aggressive deburring cycles and stainless steel polishing work. The open-web structure resists loading, which extends abrasive service life under sustained use. Licensed trades and fabrication shops running angle grinders, die grinders, or bench-mounted finishing tools will find this wheel a practical consumable for production and maintenance work.\u003c\/p\u003e\u003cp\u003eThis wheel is designed for ferrous and non-ferrous metal applications, including aluminum, carbon steel, and stainless steel. Common use cases include edge deburring after cutting or stamping, weld blending, and light surface conditioning. The 3 inch diameter and 1\/4 inch arbor fit a standard mandrel setup on portable or stationary power tools. The wheel runs in both clockwise and counterclockwise directions, which adds flexibility when paired with different tool configurations or machine setups. Minimum purchase quantity is 10 wheels per order.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHard-density 800 Series construction delivers greater edge durability than 700 Series unitized wheels\u003c\/li\u003e\n\u003cli\u003eAluminum oxide mineral is compatible with ferrous and non-ferrous metals including aluminum and stainless steel\u003c\/li\u003e\n\u003cli\u003eOpen-web design resists loading for extended abrasive service life in heavy-duty applications\u003c\/li\u003e\n\u003cli\u003eRuns clockwise and counterclockwise for versatility across tools and machines\u003c\/li\u003e\n\u003cli\u003e3 inch diameter with 1\/4 inch center arbor hole; attaches via a unitized wheel mandrel sold separately\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with portable die grinders, angle grinders, and bench finishing machines that accept a 1\/4 inch arbor mandrel.

Ensure the tool is fully powered down and disconnected from its power source before mounting or removing the wheel. Inspect the wheel for damage before each use and confirm the mandrel and spindle speed rating are compatible with the wheel. Do not exceed the rated maximum RPM of the wheel or the tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 800 Series Unitized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMineral\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDensity\u003c\/strong\u003e: Hard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.089 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 7.31 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 4.19 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 3.88 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 051115333076\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: 7000121938\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51347363397938,"sku":"7000121938","price":174.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310551890.jpg?v=1782102643","url":"https:\/\/voomisupply.com\/products\/3m-7000121938-unitized-abrasive-wheel-3-in-ao-1-4-in-arbor","provider":"Voomi Supply","version":"1.0","type":"link"}
