Built with aluminum oxide abrasive and a vitrified bond, this wheel carries a 60 grit, medium grade specification rated for both wet and dry operation. At 8 inches in diameter and 1\/2 inch thick with a 1-1\/4 inch arbor hole, it is sized for standard surface and cylindrical grinding applications. The wheel is rated to a maximum of 3600 RPM and falls under NORTON series specification 25A60-HVP2. Hardness code H and a semi-friable grain structure make it a workable choice for controlled stock removal across a range of ferrous workpieces.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both shop and production environments. The porous, vitrified bond structure promotes chip clearance and coolant flow, making it appropriate for wet grinding setups where heat management and surface finish consistency are priorities. Licensed machinists and tool-and-die professionals are the typical installers for this type of abrasive wheel.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive, semi-friable — effective on soft carbon steels, tool steels, and super alloys\u003c\/li\u003e\n\u003cli\u003eVitrified bond with porous structure for coolant flow and chip clearance\u003c\/li\u003e\n\u003cli\u003e60 grit, medium grade for controlled stock removal\u003c\/li\u003e\n\u003cli\u003eRated for both wet and dry operation\u003c\/li\u003e\n\u003cli\u003eType 1 flat wheel profile, no recess, no taper\u003c\/li\u003e\n\u003cli\u003eSeries specification 25A60-HVP2\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines accepting an 8 inch diameter Type 1 wheel with a 1-1\/4 inch arbor hole running at or below 3600 RPM.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eAbrasive wheel mounting must be performed by a qualified operator following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Inspect the wheel for cracks or chips before mounting and perform a ring test. Never exceed the maximum rated RPM of 3600. Ensure the machine guard is properly in place before powering the grinder.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1\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\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: H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriability\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Pink\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWet\/Dry Operation\u003c\/strong\u003e: Wet and Dry\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries Specification\u003c\/strong\u003e: 25A60-HVP2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.8 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: 66253019356\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541763424562,"sku":"66253019356","price":92.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bb78a8c6c6955ba987313283435d9df7.jpg?v=1785884314","url":"https:\/\/voomisupply.com\/products\/norton-66253019356-surface-grinding-wheel-8in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
