It measures 6 inches in diameter, 0.25 inches thick, with a 1.25-inch arbor hole. The wheel is made from aluminum oxide abrasive bonded with a vitrified bond, delivering consistent cut rates and free-cutting action at a maximum speed of 4140 RPM. At a 60-grit, K-hardness (medium) rating, it is well-suited to moderate material removal where surface finish and wheel longevity both matter. Weight is approximately 0.58 pounds. This wheel is installed by machinists, toolroom technicians, and maintenance grinders working on production or job-shop equipment.\u003c\/p\u003e\u003cp\u003eThis wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. It performs across a broad material range including 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The porous structure of the wheel promotes coolant flow and chip clearance, reducing heat buildup during extended grinding passes. The 32A series designation reflects Norton's aluminum oxide formulation optimized for tool steels and ferrous alloys common in precision grinding applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 1 straight wheel profile with no recess, no taper — direct drop-in fit for standard arbor setups\u003c\/li\u003e\n\u003cli\u003e60-grit aluminum oxide abrasive for medium stock removal with controlled surface finish\u003c\/li\u003e\n\u003cli\u003eK hardness (medium grade) vitrified bond maintains wheel integrity under consistent load\u003c\/li\u003e\n\u003cli\u003ePorous structure aids coolant penetration and swarf clearance during wet or dry grinding\u003c\/li\u003e\n\u003cli\u003eRated to 4140 RPM maximum — verify machine RPM before mounting\u003c\/li\u003e\n\u003cli\u003eCompatible with a broad material range including stainless steel, tool steel, cast iron, and aluminum\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.

Power down and lock out the grinder before installing or removing the wheel. Inspect the wheel for cracks or chips before mounting — never mount a damaged wheel. Confirm the machine spindle speed does not exceed the 4140 RPM maximum rating stamped on the wheel, and always perform a no-load ring test and trial run behind a guard before grinding.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 6 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\u003eWheel Type\u003c\/strong\u003e: Type 1 (Straight, No Recess)\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\u003eGrit\u003c\/strong\u003e: 60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: K\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: 4140\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\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecifications Code\u003c\/strong\u003e: 32A60-KVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.58 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: 66252835786\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540842545458,"sku":"66252835786","price":80.93,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/90846e4ef910346ab8d7acaa1d8e4859.jpg?v=1785864760","url":"https:\/\/voomisupply.com\/products\/norton-66252835786-surface-grinding-wheel-60-grit-6-in","provider":"Voomi Supply","version":"1.0","type":"link"}
