Built with aluminum oxide coated cloth flaps, this wheel delivers consistent extra fine material removal at 320 grit. The shank mount style allows direct chucking into die grinders, flex shafts, and rotary tools. Rated to 40,000 RPM, it handles high-speed finishing passes without flap separation. At 0.375 inches in diameter and 0.375 inches face width, it is well suited for small-bore work, port finishing, and detail deburring where larger wheels cannot reach. Machinists, tool and die techs, and fabricators are the primary users.\u003c\/p\u003e\u003cp\u003eThis mounted flap wheel is used in metalworking, fabrication, and maintenance applications requiring fine surface finishing in restricted areas. Typical scenarios include deburring drilled holes, blending welds in tight joints, and finish work on die cavities or mold surfaces. The 1\/8 inch shank diameter is the standard size for most die grinder collets and rotary tool chucks, making this wheel a straightforward drop-in for most existing setups. It is appropriate for use on ferrous metals, non-ferrous metals, and other hard materials where 320 grit extra fine finishing is called for.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e320 grit aluminum oxide coated cloth flaps for extra fine surface finishing\u003c\/li\u003e\n\u003cli\u003e0.375 inch diameter and 0.375 inch face width for small-bore and contoured applications\u003c\/li\u003e\n\u003cli\u003e1\/8 inch shank diameter fits standard die grinder and rotary tool collets\u003c\/li\u003e\n\u003cli\u003e40,000 RPM maximum speed rating for high-speed finishing passes\u003c\/li\u003e\n\u003cli\u003eCloth backing material supports consistent flap flex and uniform abrasion\u003c\/li\u003e\n\u003cli\u003eNo interleaf construction for direct flap-to-workpiece contact\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with die grinders, flex shafts, and rotary tools equipped with a 1\/8 inch collet.

Always confirm the tool spindle speed does not exceed the 40,000 RPM maximum rating marked for this wheel. Inspect flaps for wear or separation before each use and discard any wheel showing damage. Eye protection and appropriate PPE are required during grinding and finishing operations per applicable shop safety standards.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFace Width\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 320\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Extra Fine\u003c\/li\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\u003eBacking Material\u003c\/strong\u003e: Cloth\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Shank\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 40,000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterleaf\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MERIT ABRASIVES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 08834137475\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT","offers":[{"title":"Default Title","offer_id":51562614784306,"sku":"08834137475","price":16.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9c256cd8867964c00d7e04ba02d1f70.jpg?v=1786480827","url":"https:\/\/voomisupply.com\/products\/merit-abrasives-08834137475-mounted-flap-wheel-320-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
