It measures 14 inches in diameter and 2 inches thick, with a 5-inch arbor hole and a single-side recess of 8 inches diameter by 1 inch deep. The 60-grit, K-hardness (medium grade) bond specification — 60K8V32A — delivers a balance of cut rate and wheel life suited to production surface and cylindrical grinding applications. Rated at a maximum of 2320 RPM, this wheel is intended for use by machinists and grinding technicians operating industrial grinding equipment.\u003c\/p\u003e\n\u003cp\u003eThe 66253246888 is designed for use on surface grinders and cylindrical grinders in both job shop and production environments. It handles a broad range of materials including 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The Type 5 recessed profile supports coolant flow and reduces thermal loading at the grinding face, making it appropriate for precision flat-surface work and OD grinding where heat control and consistent surface finish are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 5 single-side recess geometry — 8-inch recess diameter, 1-inch recess depth\u003c\/li\u003e\n  \u003cli\u003e60 grit, K hardness, vitrified bond — specification 60K8V32A\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive, medium grade, non-porous structure\u003c\/li\u003e\n  \u003cli\u003eRated for 2320 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eCompatible with wide material range including stainless, carbon steels, tool steels, and cast iron\u003c\/li\u003e\n  \u003cli\u003eBlue and gray wheel color consistent with NORTON 32A series identification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eSuitable for use with surface grinders and cylindrical grinders.

Always inspect the wheel for cracks or chips using a ring test before mounting, and never exceed the rated maximum RPM of 2320. Power down and lock out the grinder before changing wheels, and ensure the arbor flange and blotter are properly seated before tightening. A fresh wheel should be trued and dressed before use to ensure concentricity and correct profile.\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 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\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\u003eFull Specification\u003c\/strong\u003e: 60K8V32A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Diameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Depth\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: One-Side\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 2320\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Blue and Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11.43 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: 66253246888\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538303811890,"sku":"66253246888","price":282.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a63b0ca869df879150f70d2ed2513dd7.jpg?v=1785822416","url":"https:\/\/voomisupply.com\/products\/norton-66253246888-surface-grinding-wheel-14in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
