It uses an aluminum oxide abrasive bonded with a vitrified bond system, producing consistent cut rates and predictable wear. The wheel measures 7 inches in diameter, 0.5 inches thick, with a 1.25-inch arbor hole. Rated to 3600 RPM, it carries an H hardness code and medium grade classification under the 32A series specification. Licensed HVAC, metalworking, and machining professionals install this wheel on surface grinders, cylindrical grinders, and CNC cutting tool machines.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding operations in both job-shop and production environments. Compatible material applications include 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The porous, vitrified bond structure promotes chip clearance and coolant flow, making it a practical choice for wet or dry surface grinding passes where heat management is a priority.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive for reliable stock removal on ferrous and non-ferrous workpieces\u003c\/li\u003e\n\u003cli\u003eVitrified bond with porous structure supports chip clearance and consistent wheel breakdown\u003c\/li\u003e\n\u003cli\u003eH hardness code, medium grade for balanced cut aggressiveness and wheel life\u003c\/li\u003e\n\u003cli\u003e60 grit for moderate material removal with acceptable surface finish\u003c\/li\u003e\n\u003cli\u003eType 1 straight profile with no recess for straightforward mounting\u003c\/li\u003e\n\u003cli\u003e3600 RPM maximum speed rating for use on standard surface and cylindrical grinders\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.

Inspect the wheel for cracks or chips before mounting and perform a ring test. Power down and lock out the grinder before changing wheels. Never exceed the maximum RPM stamped on the wheel or listed in the supplier documentation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\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: Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries Specification\u003c\/strong\u003e: 32A60-HVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.59 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: 66252940879\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51543149707570,"sku":"66252940879","price":101.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/83b14d22833fbc8930ea831d02de4791.jpg?v=1785916471","url":"https:\/\/voomisupply.com\/products\/norton-66252940879-surface-grinding-wheel-7in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
