Built with white aluminum oxide abrasive and a vitrified bond, it delivers consistent, friable cutting action that continuously exposes fresh grain during use. At 3 inches in diameter with a 0.25-inch face width and a maximum operating speed of 7,640 RPM, this wheel suits bench grinder and pedestal grinder setups where controlled material removal and edge refinement are required. Hardness Code J indicates a medium-hard grade that releases grain under moderate pressure, making it appropriate for precision tool sharpening and reconditioning of high-speed steel and similar tooling.\u003c\/p\u003e\n\u003cp\u003eThis wheel is used in toolroom and maintenance shop environments where technicians sharpen cutting tools, dress lathe bits, recondition drill bits, or resurface tool faces. The Type 11 cup profile directs the abrasive face against the workpiece, providing clearance for the wheel body during sharpening operations. It is well suited to light industrial, machine shop, and skilled trade maintenance settings where consistent geometry and repeatable results are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent, controlled stock removal\u003c\/li\u003e\n  \u003cli\u003eType 11 flaring cup geometry provides clearance during tool grinding operations\u003c\/li\u003e\n  \u003cli\u003e60 grit medium grade removes material efficiently while leaving a refinished edge\u003c\/li\u003e\n  \u003cli\u003eFriable grain structure continuously fractures to expose fresh cutting edges\u003c\/li\u003e\n  \u003cli\u003eWhite wheel color allows visual inspection of workpiece contact and heat buildup\u003c\/li\u003e\n  \u003cli\u003eRated to 7,640 RPM maximum for use on standard bench and pedestal grinders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-mount replacement or standard toolroom grinding wheel for bench grinders and pedestal grinders accepting a 0.75-inch arbor hole and rated for Type 11 cup wheels at or below 7,640 RPM.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMounting and dressing of grinding wheels should be performed by a qualified machinist or toolroom technician following ANSI B11.9 and applicable OSHA abrasive wheel standards. Always shut down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation and perform a ring test per manufacturer guidelines. Never exceed the maximum RPM stamped on the wheel, and ensure the grinder spindle speed does not exceed 7,640 RPM before operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Thickness\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFace Width\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 60\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 7,640\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: White\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFriable\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 38A60-JVBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 66243529197\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538322325810,"sku":"66243529197","price":56.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c34cc80f2e42235f33ebc88cba0fee50.jpg?v=1785822973","url":"https:\/\/voomisupply.com\/products\/norton-66243529197-type-11-grinding-wheel-60-grit-3in","provider":"Voomi Supply","version":"1.0","type":"link"}
