The 9-inch diameter wheel is constructed from a Zirconia Alumina and Silicon Carbide blend bond in a resinoid bond matrix, delivering a coarse 20 grit cut rated for up to 6,600 RPM. At 0.25 inches thick with a 5\/8-11 threaded arbor hole, this wheel mounts directly to standard angle grinders and is suited for heavy grinding, weld blending, and surface prep on ferrous and non-ferrous metals. Licensed tradespeople and fabricators working in industrial, construction, and maintenance environments are the primary users.\u003c\/p\u003e\u003cp\u003eThis wheel is built for demanding grinding applications including weld removal, edge chamfering, and stock removal on steel, stainless, cast iron, and masonry substrates. The coarse 20 grit designation makes it appropriate for rapid material removal rather than finishing passes. The Type 27 depressed center profile allows the disc to be worked at a low angle to the workpiece, which reduces operator fatigue and improves control in flat or slightly contoured surfaces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e9 inches diameter Type 27 depressed center profile for low-angle grinding\u003c\/li\u003e\n\u003cli\u003eZirconia Alumina and Silicon Carbide blend abrasive for aggressive, multi-material stock removal\u003c\/li\u003e\n\u003cli\u003eCoarse 20 grit rating optimized for rapid weld blending and surface prep\u003c\/li\u003e\n\u003cli\u003eResinoid bond with Hardness Code R for controlled wear and consistent cut rate\u003c\/li\u003e\n\u003cli\u003e5\/8-11 threaded connector mounts directly to standard angle grinder spindles\u003c\/li\u003e\n\u003cli\u003e6,600 RPM maximum operating speed\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with angle grinders equipped with a 5\/8-11 threaded spindle.

Always confirm the grinder spindle speed does not exceed the 6,600 RPM maximum rating stamped on the wheel before mounting. Inspect the wheel for cracks or damage before each use and never operate a damaged wheel. Use the appropriate guard and personal protective equipment including face shield, gloves, and hearing protection per applicable ANSI B7.1 safety codes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 27 Depressed Center\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Zirconia Alumina and Silicon Carbide Blend\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 6,600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resinoid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Thread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Compatibility\u003c\/strong\u003e: Angle Grinder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.70 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\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: 66252843261\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540883276082,"sku":"66252843261","price":41.46,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2e9fd54e86278a02449cf5d39606daa2.jpg?v=1785865376","url":"https:\/\/voomisupply.com\/products\/norton-66252843261-type-27-grinding-wheel-9in-20-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
