Built with aluminum oxide abrasive and a resinoid bond, this 4.5-inch wheel delivers coarse 24-grit cutting action suited to weld grinding, surface prep, and deburring tasks. It is rated to a maximum of 13,580 RPM and fits standard 7\/8-inch arbor angle grinders. At 0.155 pounds, it is lightweight without sacrificing durability. The resinoid bond holds the abrasive grain firmly under load, making it a reliable choice for sustained grinding passes in metal fabrication and maintenance environments.\u003c\/p\u003e\u003cp\u003eThis wheel is used in metalworking, fabrication shops, and field maintenance settings where fast material removal is required. The Type 27 raised-hub profile keeps the grinding face at a low angle to the workpiece, reducing gouging and improving control on flat and curved surfaces. Typical applications include grinding welds flush, cleaning mill scale, removing rust, and prepping surfaces before welding or coating. It is well suited to ferrous metals and is installed on 4.5-inch angle grinders by fabricators, pipefitters, ironworkers, and maintenance technicians.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 27 depressed-center profile for low-angle flat and weld grinding\u003c\/li\u003e\n\u003cli\u003e24-grit coarse aluminum oxide abrasive for aggressive stock removal\u003c\/li\u003e\n\u003cli\u003eResinoid bond construction holds grain under sustained load\u003c\/li\u003e\n\u003cli\u003e13,580 maximum RPM rating for standard 4.5-inch angle grinders\u003c\/li\u003e\n\u003cli\u003e7\/8-inch arbor hole fits common angle grinder spindle sizes\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.155 pounds for reduced operator fatigue\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on 4.5-inch angle grinders with a 7\/8-inch arbor spindle and a minimum no-load speed rating of 13,580 RPM or higher.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and removal of grinding wheels must be performed by qualified personnel following ANSI B7.1 safety standards and the grinder manufacturer instructions. Confirm the grinder spindle speed does not exceed the 13,580 RPM maximum rating marked on the wheel before mounting. Disconnect power and allow the tool to come to a complete stop before changing wheels. Always use the correct flange size and inspect the wheel for cracks or damage before each use — do not use a damaged wheel.\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\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 24\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\u003eWheel Diameter\u003c\/strong\u003e: 4.5 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\u003eHole Size\u003c\/strong\u003e: 0.875 inches (7\/8 arbor)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 13,580\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Type\u003c\/strong\u003e: Arbor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 4.5 x 4.5 x 0.43 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.155 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: NORTON\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66252843594\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51699980697906,"sku":"66252843594","price":28.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8f0be5e81d163a5e67b2e76631095de0.jpg?v=1788384457","url":"https:\/\/voomisupply.com\/products\/norton-66252843594-type-27-grinding-wheel-4-5-in-24-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
