The wheel measures 7 inches in diameter and 0.25 inches thick, with a 0.875-inch arbor hole for standard angle grinder mounting. It uses aluminum oxide abrasive bonded with a resinoid bond and carries a coarse 20-grit rating, making it well suited for heavy stock removal, weld grinding, and surface preparation. The resinoid bond and reinforced fiberglass construction give it structural integrity at operating speeds up to 8,600 RPM. Wheel hardness is rated medium with a hardness code of P.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for use on angle grinders in metal fabrication, construction, and maintenance applications. The Type 27 depressed-center profile keeps the grinding face closer to flat work surfaces, which is useful for grinding flush welds, cleaning plate steel, and removing scale or slag. It is commonly used by ironworkers, pipefitters, fabricators, and general maintenance technicians working on structural steel, carbon steel, and similar ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e20-grit coarse aluminum oxide abrasive for aggressive stock removal\u003c\/li\u003e\n  \u003cli\u003eType 27 depressed-center profile allows flush grinding on flat surfaces\u003c\/li\u003e\n  \u003cli\u003eResinoid bond with reinforced fiberglass construction for durability under load\u003c\/li\u003e\n  \u003cli\u003eMedium hardness rating (hardness code P) balances cut rate and wheel life\u003c\/li\u003e\n  \u003cli\u003eSemi-friable abrasive resists glazing and maintains cutting action through the wheel life\u003c\/li\u003e\n  \u003cli\u003eRated to 8,600 RPM for use on standard 7-inch angle grinders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement grinding wheel for standard 7-inch angle grinders equipped with a 0.875-inch arbor spindle.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified operator familiar with abrasive wheel safety. Always power down and unplug the grinder before mounting or removing a wheel. Verify that the grinder spindle speed does not exceed the maximum wheel RPM rating of 8,600 before operation. Inspect the wheel for cracks or damage before each use and never use a damaged wheel.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 7 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 27\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: 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: 8,600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resinoid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFriable\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReinforced\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnector Type\u003c\/strong\u003e: Arbor\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.9 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 66252849377\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542851060018,"sku":"66252849377","price":27.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a34bf56fd6afcd056d124eaf4a7deee2.jpg?v=1785909103","url":"https:\/\/voomisupply.com\/products\/norton-66252849377-7-inch-grinding-wheel-20-grit-type-27","provider":"Voomi Supply","version":"1.0","type":"link"}
