At 7 inches in diameter, 1\/2 inch thick, and bored to a 1-1\/4 inch hole, this wheel fits standard surface grinder spindles. The 60-grit, H-hardness medium-grade bond delivers controlled stock removal on a broad range of ferrous and non-ferrous workpiece materials. The vitrified bond provides consistent structure and free-cutting action, making it well-suited for precision surface grinding applications in tool rooms and production environments. Licensed HVAC technicians, machinists, and maintenance professionals working with hard alloys or cast iron specify this wheel for its predictable performance and dimensional stability under load.\u003c\/p\u003e\n\u003cp\u003eThis wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. It handles a wide range of materials including 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The non-porous, non-recessed, non-tapered Type 1 flat wheel profile is the standard configuration for surface grinding applications in both job shop and production settings. It is appropriate for both light finishing passes and moderate material removal on flat workpiece surfaces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 1 flat wheel profile — no recess, no taper, direct spindle mount\u003c\/li\u003e\n  \u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent, free-cutting action\u003c\/li\u003e\n  \u003cli\u003e60 grit, H hardness (medium grade) for balanced stock removal and surface finish\u003c\/li\u003e\n  \u003cli\u003eRated to 3600 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eCompatible with a broad range of ferrous and non-ferrous materials including stainless, tool steels, and cast iron\u003c\/li\u003e\n  \u003cli\u003eSeries 32A Type 1 specification code: 60H8V32A\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before installation — never mount a damaged wheel. Ring-test the wheel before use, ensure flanges and blotters are correctly seated, and run the wheel at operating speed for at least one minute with guards in place before bringing it into contact with the workpiece.\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 1\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\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\u003eGrit\u003c\/strong\u003e: 60\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 60H8V32A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Blue \/ Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.86 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\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: 66253246815\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541292548402,"sku":"66253246815","price":31.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5e7bfcf9896192a34c76c49a64fb890e.jpg?v=1785871539","url":"https:\/\/voomisupply.com\/products\/norton-66253246815-surface-grinding-wheel-60-grit-7in","provider":"Voomi Supply","version":"1.0","type":"link"}
