Built with ceramic alumina abrasive and a vitrified bond, this wheel delivers controlled, consistent stock removal on hardened steels and tool steels. It measures 5 inches in diameter with a 1-3\/4 inch overall thickness and a 1\/4 inch face width. Rated to a maximum of 4,585 RPM, the K hardness code and semi-friable grain structure help maintain sharp cutting edges throughout the wheel's life. This wheel is intended for use by tool and die specialists, machinists, and industrial grinding professionals.\u003c\/p\u003e\u003cp\u003eThis grinding wheel is suited for tool room environments, production grinding operations, and bench grinder setups where tight dimensional control is required. The Type 11 cup profile makes it appropriate for face grinding, off-hand tool sharpening, and reconditioning of cutting tools such as end mills, drill bits, and form tools. The ceramic alumina grain is well matched to applications on hardened high-speed steel and alloy tool steel workpieces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic alumina abrasive for consistent cut rate on hardened tool steels\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigid support and maintains wheel form\u003c\/li\u003e\n\u003cli\u003eK hardness (medium grade) balances wheel life with free cutting action\u003c\/li\u003e\n\u003cli\u003eSemi-friable grain structure promotes self-sharpening during use\u003c\/li\u003e\n\u003cli\u003eNon-porous construction reduces loading on ferrous materials\u003c\/li\u003e\n\u003cli\u003eType 11 cup profile designed for face grinding and tool reconditioning\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard toolroom grinding wheel for bench grinders and pedestal grinders equipped with a 1-1\/4 inch arbor bore and capable of accommodating a 5 inch diameter Type 11 wheel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tool grinding technician following ANSI B7.1 safe mounting practices for abrasive wheels. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before mounting and perform a ring test per standard procedure. Never exceed the rated maximum RPM of 4,585; confirm the grinder speed plate before operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic Alumina\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: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Thickness\u003c\/strong\u003e: 1-3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFace Width\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size (Arbor Bore)\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHub Diameter\u003c\/strong\u003e: 3-3\/4 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: K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriability\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorosity\u003c\/strong\u003e: Non-Porous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 4,585\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 5SG60-KVS\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: 66252830737\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541274394930,"sku":"66252830737","price":321.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/34c19dd870447e8763562bafe468a3e0.jpg?v=1785871252","url":"https:\/\/voomisupply.com\/products\/norton-66252830737-type-11-grinding-wheel-5-in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
