Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cut rates and predictable wheel breakdown. The wheel measures 7 inches in diameter, 1\/4 inch thick, and carries a 1-1\/4 inch arbor hole. Grit is 60 with a medium (I) hardness rating, making it suited for moderate material removal without excessive surface loading. Rated to 3600 RPM, it meets typical surface and cylindrical grinder operating speeds. Licensed grinding technicians and toolroom machinists are the primary installers.\u003c\/p\u003e\u003cp\u003eThis wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. Stated material applications include 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is a flat, straight-profile wheel with no recess and no taper, following standard Type 1 geometry. The Series 32A designation indicates a well-established aluminum oxide specification commonly specified in production grinding and toolroom environments for general-purpose ferrous and non-ferrous work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive for reliable cut rate on steel, cast iron, and aluminum\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides open, porous structure for cool cutting and consistent wheel performance\u003c\/li\u003e\n\u003cli\u003e60 grit medium grade balances stock removal speed with acceptable surface finish\u003c\/li\u003e\n\u003cli\u003eType 1 flat wheel geometry with no recess — straightforward mounting to standard arbors\u003c\/li\u003e\n\u003cli\u003e3600 RPM max speed rating fits common surface and cylindrical grinder spindle speeds\u003c\/li\u003e\n\u003cli\u003eSeries 32A specification (32A60-IVBE) for traceable, repeatable performance across batches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eSpecified for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always ring-test the wheel before mounting and inspect for cracks or damage. Power down and lockout the grinder before changing wheels, and never exceed the maximum RPM marked on the wheel. A flanged arbor with properly sized blotters should be used to distribute clamping load evenly across the wheel face.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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 (Straight)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 32A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: 32A60-IVBE\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: 0.25 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\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: I\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\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: Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.79 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: 66252939548\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539009601842,"sku":"66252939548","price":96.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b7b1f8e918ca37b1781ca162d3871cf.jpg?v=1785832714","url":"https:\/\/voomisupply.com\/products\/norton-66252939548-surface-grinding-wheel-60-grit-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
