At 14 inches in diameter, 1.5 inches thick, with a 5-inch arbor hole and a 60 grit medium-grade abrasive, this wheel delivers consistent stock removal and controlled surface finish. The H hardness code indicates a soft-to-medium bond that releases dull grains efficiently, maintaining cut rate across extended use. Maximum operating speed is rated at 1,775 RPM. Rated weight is 11.43 pounds. This wheel is installed and operated by skilled grinding machinists and tool-and-die professionals in production and job shop environments.\u003c\/p\u003e\n\u003cp\u003eThis grinding wheel is suited for surface grinding, cylindrical grinding, and CNC cutting tool machine applications. 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 32A Series designation identifies the specific aluminum oxide grain structure, which is formulated for aggressive cutting on hardened and abrasion-resistant workpieces. Typical use is in horizontal and vertical spindle surface grinders in both residential machine shops and commercial production facilities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eType 1 straight wheel profile with no recess — maximizes usable abrasive volume\u003c\/li\u003e\n  \u003cli\u003e60 grit medium-grade aluminum oxide abrasive for balanced stock removal and surface finish\u003c\/li\u003e\n  \u003cli\u003eH hardness (soft bond) promotes self-sharpening action to extend wheel life on hard materials\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigidity, porosity control, and thermal stability during wet or dry grinding\u003c\/li\u003e\n  \u003cli\u003eNon-tapered, non-porous construction for consistent grinding geometry across the wheel face\u003c\/li\u003e\n  \u003cli\u003eCompatible with surface grinders, cylindrical grinders, and CNC cutting tool machines\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Suitable for grinding 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Verify spindle speed does not exceed 1,775 RPM and that the machine arbor accepts a 5-inch hole mount before installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or grinding specialist following ANSI B7.1 safety requirements for the use, care, and protection of abrasive wheels. Always power down and lock out the grinder before mounting or removing the wheel. Perform a ring test before mounting to check for cracks, and run the wheel at operating speed with the guard in place for at least one minute before bringing it into contact with the workpiece. Never exceed the rated maximum RPM of 1,775.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 5 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: H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 1,775\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\u003eSeries\u003c\/strong\u003e: 32A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 60H8V32A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\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: Blue \/ Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11.43 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 66253246807\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51543022141746,"sku":"66253246807","price":215.36,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/684b5b7be5c719ec06f28803934ede9e.jpg?v=1785913873","url":"https:\/\/voomisupply.com\/products\/norton-66253246807-surface-grinding-wheel-14in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
