Built with a ceramic alumina abrasive grain and a resinoid bond, this wheel delivers a coarse cut suited for weld grinding, surface preparation, and stock removal tasks. The 9-inch diameter and 1\/4-inch thickness make it a standard choice for angle grinders used in fabrication, structural steel work, and industrial maintenance. The wheel weighs approximately 1.93 pounds and threads onto a 5\/8-11 arbor. Licensed tradespeople and fabricators working on heavy grinding applications rely on this wheel's ceramic alumina construction for consistent cut rate and durability under high-pressure grinding conditions.\u003c\/p\u003e\u003cp\u003eThis wheel is intended for use on 9-inch angle grinders in both shop and field environments. Its coarse grade and ceramic alumina abrasive make it well suited for carbon steel, stainless steel, and other ferrous metals where fast stock removal is the priority. Typical applications include weld seam grinding, edge cleanup, and surface conditioning on structural components, pipe, and plate. The threaded 5\/8-11 hub provides a secure, vibration-resistant connection to compatible grinder spindles.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic alumina abrasive grain for high cut rate and extended wheel life\u003c\/li\u003e\n\u003cli\u003eResinoid bond provides durability and controlled grinding performance\u003c\/li\u003e\n\u003cli\u003eCoarse grade optimized for rapid stock removal on ferrous metals\u003c\/li\u003e\n\u003cli\u003eType 27 depressed center profile reduces interference and improves operator sight lines during grinding\u003c\/li\u003e\n\u003cli\u003e5\/8-11 threaded hub for secure mounting on standard angle grinders\u003c\/li\u003e\n\u003cli\u003eRigid, non-flexible construction maintains consistent contact pressure\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on 9-inch angle grinders equipped with a 5\/8-11 threaded spindle.

Disconnect and lock out power to the grinder before mounting or removing the wheel. Inspect the wheel for cracks or damage before each use and do not use a wheel that shows any signs of damage. Always use the correct flange hardware and ensure the wheel guard is properly in place before grinding.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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\u003eWheel Type\u003c\/strong\u003e: Type 27 Depressed Center\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic Alumina\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resinoid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Type\u003c\/strong\u003e: Threaded\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\u003eFlexible\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.93 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 66253370849\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542834544946,"sku":"66253370849","price":50.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/48be0c6b1d82ab0a94be658b42d0cc32.jpg?v=1785908811","url":"https:\/\/voomisupply.com\/products\/norton-66253370849-type-27-grinding-wheel-9in-ceramic","provider":"Voomi Supply","version":"1.0","type":"link"}
