It measures 3.5 inches in outside diameter by 1 inch wide, with a 0.625-inch center hole for arbor mounting. The abrasive is aluminum oxide on a cloth backing, rated at medium grade with an 80-grit cut. Maximum operating speed is 12,000 RPM. This wheel is suited for use on die grinders, bench grinders, and drill press setups. Metalworkers, fabricators, and maintenance technicians reach for this style of flap wheel when blending welds or cleaning up interior bores and curved surfaces.\u003c\/p\u003e\u003cp\u003eThis flap wheel is used in light industrial, fabrication shop, and maintenance environments where controlled material removal and surface finishing are required. Its unmounted design means it is installed directly onto an arbor or mandrel rather than pre-mounted on a spindle. It is well suited for deburring pipe ends, smoothing weld seams, and finishing curved or contoured workpieces where a rigid abrasive would lose contact. No interleaf construction keeps the design straightforward for standard finishing passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive on cloth backing for durable, consistent cut\u003c\/li\u003e\n\u003cli\u003e80 grit medium grade — effective for blending and moderate stock removal\u003c\/li\u003e\n\u003cli\u003e3.5-inch outside diameter by 1-inch width for broad surface contact\u003c\/li\u003e\n\u003cli\u003e12,000 RPM maximum rated speed for use on standard die grinders and drill presses\u003c\/li\u003e\n\u003cli\u003e0.625-inch center hole for direct arbor or mandrel mounting\u003c\/li\u003e\n\u003cli\u003eNo interleaf construction for straightforward finishing applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit abrasive flap wheel for use on standard arbor-mount die grinders, bench grinders, and drill press setups accepting a 0.625-inch bore unmounted flap wheel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eUnmounted flap wheels are installed and serviced by machinists, fabricators, or maintenance technicians familiar with abrasive tooling. Always power down and lock out the tool before mounting or removing the wheel. Verify that the tool spindle speed does not exceed the 12,000 RPM maximum rating marked on the wheel. Inspect the wheel for damage before each use and never exceed the rated speed, as doing so creates a safety hazard.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Cloth\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Hole Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 12,000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterleaf\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NORTON\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 63642502669\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538917982514,"sku":"63642502669","price":39.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6778cc2e5bee18240e3b8135a4947a9c.jpg?v=1785829591","url":"https:\/\/voomisupply.com\/products\/norton-63642502669-flap-wheel-80-grit-3-5x1-in-aluminum-oxide","provider":"Voomi Supply","version":"1.0","type":"link"}
