Built with aluminum oxide abrasive and a vitrified bond, it measures 8 inches in diameter, 1 inch thick, with a 1-1\/4 inch arbor hole. The 60-grit, medium-hardness (Grade I) construction delivers consistent material cut rates on surfaces that require controlled finish and dimensional accuracy. Rated at a maximum of 3,600 RPM, this wheel suits production and toolroom environments where flat-surface grinding is the primary operation. It carries the internal specification designation 32A60-IVBE.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding applications on a wide range of metalworking materials including 400-series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Compatible equipment includes surface grinders, cylindrical grinders, and CNC cutting tool machines. It is commonly installed in job shops, tool and die operations, and maintenance machining environments where consistent wheel geometry is required across multiple passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive for reliable cut rate across ferrous and non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigidity and consistent wheel form retention\u003c\/li\u003e\n\u003cli\u003e60-grit medium grade balances stock removal speed with surface finish quality\u003c\/li\u003e\n\u003cli\u003eGrade I hardness (medium) supports broad material compatibility without excessive glazing\u003c\/li\u003e\n\u003cli\u003ePorous structure promotes chip clearance and cooler grinding action\u003c\/li\u003e\n\u003cli\u003eType 1 straight profile with no recess, no taper — straightforward mounting and dressing\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.

Always power down and lock out the grinder before mounting or removing a wheel. Perform a ring test before mounting — a cracked wheel must never be used. Confirm the machine spindle speed does not exceed the 3,600 RPM maximum rating stamped on the wheel, and run the wheel under guard at operating speed for at least one minute before bringing it into contact with the workpiece.\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: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 1-1\/4 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 (Hardness Code I)\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 (Straight, No Recess, No Taper)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3,600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: 32A60-IVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4.18 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\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: 66253044624\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539492995378,"sku":"66253044624","price":167.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d63c0bb8286ef0f48b125d08e9ddd3f5.jpg?v=1785841647","url":"https:\/\/voomisupply.com\/products\/norton-66253044624-surface-grinding-wheel-8in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
