The wheel measures 6 inches in diameter with a 0.5 inch overall thickness and a 0.375 inch face width, mounted on a 1.25 inch arbor hole. It carries a 60-grit, J-hardness (medium) rating, making it well suited for moderate stock removal on tool steel and similar materials. Maximum operating speed is 4,140 RPM. Installation and use require a compatible bench or pedestal grinder. The vitrified bond provides consistent grain exposure and free-cutting action throughout the wheel life.\u003c\/p\u003e\u003cp\u003eThis wheel is a standard fit for bench grinders and pedestal grinders used in tool rooms, maintenance shops, and production environments. It is appropriate for resharpening cutting tools, deburring, and light surface grinding where a medium-grit aluminum oxide abrasive is the correct choice. The Type 12 form factor features a recessed face, which positions the grinding surface for specific tool-grinding fixtures and cup-wheel applications. Typical users include machinists, maintenance technicians, and tool-and-die professionals who require consistent, controlled material removal.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 12 cup wheel form with recessed face for tool-grinding fixture compatibility\u003c\/li\u003e\n\u003cli\u003e60-grit aluminum oxide abrasive for medium stock removal on tool steel\u003c\/li\u003e\n\u003cli\u003eJ hardness (medium) vitrified bond for consistent grain exposure and long wheel life\u003c\/li\u003e\n\u003cli\u003e4,140 RPM maximum operating speed\u003c\/li\u003e\n\u003cli\u003eNon-porous construction for uniform grinding action\u003c\/li\u003e\n\u003cli\u003eSpecification grade 32A60-JVBE for traceability and replacement ordering\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit grinding wheel for bench grinders and pedestal grinders accepting a 6 inch diameter, 1.25 inch arbor hole, Type 12 cup wheel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGrinding wheel installation must be performed by a qualified operator following ANSI B7.1 safety requirements. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the rated maximum RPM. Use proper flanges and a paper blotter on each side of the wheel as required by applicable safety standards.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Grade\u003c\/strong\u003e: 32A60-JVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: J\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Thickness\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFace Width\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 4,140\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.603 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: 66252836966\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51543073423666,"sku":"66252836966","price":117.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c457aaf7cfe7ae9ea5b235f2f8e88f5d.jpg?v=1785914905","url":"https:\/\/voomisupply.com\/products\/norton-66252836966-type-12-grinding-wheel-6-in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
