Constructed from aluminum oxide abrasive with a vitrified bond, it measures 8 inches in diameter, 3\/4 inches thick, and carries a 1-1\/4 inch arbor hole. At 60 grit with H hardness (medium grade), it delivers an efficient cut rate suited to surface, cylindrical, and CNC tool grinding. Rated to 3600 RPM, it meets the demands of both manual and automated grinding setups. The porous structure of the vitrified bond aids in coolant flow and chip clearance during extended runs.\u003c\/p\u003e\u003cp\u003eThis wheel is engineered for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. It is well suited to grinding 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The 32A series designation identifies the specific aluminum oxide grain blend Norton uses for consistent cut and form retention across medium-to-hard workpiece materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent cut and long wheel life\u003c\/li\u003e\n\u003cli\u003e60 grit, H hardness (medium grade) balances material removal rate and surface finish\u003c\/li\u003e\n\u003cli\u003ePorous wheel structure promotes coolant flow and chip clearance\u003c\/li\u003e\n\u003cli\u003eType 1 straight wheel profile fits standard surface and cylindrical grinder spindles\u003c\/li\u003e\n\u003cli\u003e3600 RPM max operating speed suits common bench and floor-standing grinders\u003c\/li\u003e\n\u003cli\u003eNo recess, no taper — straightforward mount and dress\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with surface grinders, cylindrical grinders, and CNC cutting tool machines accepting a Type 1 straight wheel with an 8 inch diameter, 3\/4 inch width, and 1-1\/4 inch arbor hole.

Always inspect the wheel for cracks or chips before mounting — never mount a damaged wheel. Power down and lock out the grinder before changing wheels, and verify the machine spindle speed does not exceed the 3600 RPM rating marked on the wheel. Use proper flanges and blotters as specified by the machine manufacturer, and conduct a free-spin safety test before bringing the wheel into contact with the workpiece.\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\u003eSeries\u003c\/strong\u003e: 32A Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 (Straight, No Recess)\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: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 3\/4 inches\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\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\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\u003eMaterial Application\u003c\/strong\u003e: 400 Series Stainless, Hard Carbon Steels, Soft Carbon Steels, Tool Steels, Aluminum, Cast Iron, Ductile Iron, Gray Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.69 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: 66253044168\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541946630450,"sku":"66253044168","price":184.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0451b2ca6e161f9580f419d81d30478d.jpg?v=1785888211","url":"https:\/\/voomisupply.com\/products\/norton-66253044168-surface-grinding-wheel-60-grit-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
