Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent stock removal on ferrous metals. It measures 8 inches in diameter and 1\/2 inch thick, with a 1-1\/4 inch arbor hole. The 60-grit medium-grade specification and H hardness code suit it for controlled material removal passes on hard and soft carbon steels and tool steels. Maximum operating speed is rated at 3600 RPM. Installation and operation are handled by machinists and tool-and-die professionals using compatible grinding machines.\u003c\/p\u003e\u003cp\u003eThis wheel is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both wet and dry grinding conditions. Its ruby-colored aluminum oxide construction and porous structure support heat dissipation during extended grinding cycles. Typical applications include toolroom work, die maintenance, and production surface grinding of hard carbon steels, soft carbon Steels, and tool steels where a medium-grade, moderately hard wheel is appropriate.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent, repeatable grinding action\u003c\/li\u003e\n\u003cli\u003e60-grit medium grade suited for stock removal on carbon and tool steels\u003c\/li\u003e\n\u003cli\u003eH hardness code (Soft-to-Medium range) helps the wheel shed dull grains and reduce heat buildup\u003c\/li\u003e\n\u003cli\u003ePorous wheel structure promotes coolant flow in wet grinding setups\u003c\/li\u003e\n\u003cli\u003eRated for wet and dry operation up to 3600 RPM\u003c\/li\u003e\n\u003cli\u003eType 1 flat wheel profile with no recess — compatible with standard surface and cylindrical grinder flanges\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.

Confirm machine spindle speed does not exceed the 3600 RPM maximum rating before mounting.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGrinding wheels must be installed, dressed, and operated by qualified personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always de-energize and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips using a ring test before every installation, and never exceed the rated maximum RPM. Use appropriate flanges, blotters, and guards as specified by the machine manufacturer.\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\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: H\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 Type\u003c\/strong\u003e: Type 1 (No Recess)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Ruby\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Yes\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\u003eSpecification Code\u003c\/strong\u003e: 48A60-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: 66253019352\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540686111026,"sku":"66253019352","price":108.59,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/089a6c09eaf87eb2763269c65b6d79a4.jpg?v=1785861915","url":"https:\/\/voomisupply.com\/products\/norton-66253019352-surface-grinding-wheel-8in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
