The wheel measures 7 inches in diameter with a 0.5 inch overall thickness and a 0.4375 inch face width, mounted on a 1.25 inch arbor hole. Rated at a maximum of 3,550 RPM, it carries a 60 grit, medium hardness (Grade K) abrasive spec — designated 32A60-KVBE. This wheel is installed and used by machinists, tool-and-die technicians, and grinding shop professionals working with ferrous and non-ferrous tooling materials.\u003c\/p\u003e\n\u003cp\u003eDesigned for use on bench or pedestal tool-and-cutter grinders, this wheel suits applications including resharpening milling cutters, reamers, taps, and similar cutting tools. The Type 12 profile — a dish-shaped wheel — allows clearance grinding and sharpening of multi-fluted cutting tools where a flat wheel face cannot reach the cutting geometry. It is appropriate for light to medium stock removal in precision grinding environments. The non-porous, vitrified bond provides consistent cutting action and resistance to loading during tool reconditioning work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 12 dish profile for clearance and tool-geometry grinding\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive — suitable for resharpening high-speed steel and general-purpose tooling\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigid, consistent abrasive retention\u003c\/li\u003e\n  \u003cli\u003e60 grit medium grade (Hardness Code K) for controlled stock removal with moderate finish\u003c\/li\u003e\n  \u003cli\u003e3,550 RPM maximum speed rating for standard bench and pedestal grinder use\u003c\/li\u003e\n  \u003cli\u003eNon-porous structure minimizes loading on tool steel surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or aftermarket grinding wheel for bench and pedestal tool-and-cutter grinders accepting a 7 inch diameter, 1.25 inch arbor hole, Type 12 wheel.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eGrinding wheel mounting and dressing should be performed by a qualified machinist or grinding technician following ANSI B7.1 safe-use standards. Always power down and lock out the grinder before changing wheels. Inspect the wheel for cracks or chips using a ring test before mounting — do not use a damaged wheel. Ensure the spindle RPM rating of the grinder does not exceed the 3,550 RPM maximum speed marked on this wheel.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 12 (Dish)\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\u003eWheel Diameter\u003c\/strong\u003e: 7 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: 0.4375 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\u003eGrit\u003c\/strong\u003e: 60\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium (Hardness Code K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Spec Designation\u003c\/strong\u003e: 32A60-KVBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3,550\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: 0.82 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: 66252941647\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538386485554,"sku":"66252941647","price":120.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6e4d49ee4c9e0247fa3bf661056200a4.jpg?v=1785824075","url":"https:\/\/voomisupply.com\/products\/norton-66252941647-type-12-grinding-wheel-7-in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
