This non-woven aluminum oxide wheel carries an extra hard density rating, placing it at the aggressive end of the Standard Abrasives 900 Series lineup. The construction delivers high toughness and edge durability, making it well suited for removing stubborn burrs and polishing harder metals where softer wheels wear down too quickly. Designed to mount via a unitized wheel mandrel, it installs on die grinders, bench grinders, and similar rotary tools used in fabrication and maintenance shops.\u003c\/p\u003e\u003cp\u003eThis wheel is a practical choice for metalworking professionals in manufacturing, fabrication, welding, and industrial maintenance applications. The aluminum oxide mineral performs reliably on steel, stainless steel, cast iron, aluminum, and other common metals. The extra hard density provides longer service life compared to standard 800 Series unitized wheels when working on hard metals or heavy material removal tasks. The wheel accepts both clockwise and counterclockwise rotation, which adds flexibility when pairing with different tool and machine configurations on the shop floor.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eExtra hard density aluminum oxide construction for aggressive edge deburring and finishing on hard metals\u003c\/li\u003e\n\u003cli\u003eNon-woven abrasive wheel design delivers consistent cut rate throughout wheel life\u003c\/li\u003e\n\u003cli\u003eRuns clockwise and counterclockwise for greater tool and machine compatibility\u003c\/li\u003e\n\u003cli\u003eHigher material density and edge durability than 800 Series unitized wheels for extended life on heavy-duty tasks\u003c\/li\u003e\n\u003cli\u003eAluminum oxide mineral is compatible with ferrous and non-ferrous metals including aluminum\u003c\/li\u003e\n\u003cli\u003eCenter-hole design mounts to a standard unitized wheel mandrel (sold separately)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with rotary tools that accept a unitized wheel mandrel.

Power down and disconnect the tool from its power source before mounting or removing the wheel. Verify that the tool RPM rating meets or exceeds the wheel RPM rating before operation. The unitized wheel mandrel required for mounting is sold separately and must be correctly seated and tightened per the mandrel manufacturer instructions.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 3 inches\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: 900 Series\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDensity Grade\u003c\/strong\u003e: Extra Hard\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e: Non-Woven Unitized\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRotation\u003c\/strong\u003e: Clockwise and Counterclockwise\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.889 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 7.31 x 4.19 x 3.88 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 051115356877\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: 7100049934\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51347365232946,"sku":"7100049934","price":158.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310528840.jpg?v=1782102705","url":"https:\/\/voomisupply.com\/products\/3m-7100049934-unitized-abrasive-wheel-3-inch-aluminum-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
