At 14 inches in diameter and 1-1\/2 inches thick, it carries a 5-inch arbor hole and spins up to 2320 RPM. Hardness code I places it in the medium range, giving it enough bond retention to hold grain under aggressive cuts while still allowing controlled breakdown as the wheel wears. The 32A Series designation identifies this as a production-grade wheel built for consistent, repeatable performance on industrial grinding equipment.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for use on CNC cutting tool machines, cylindrical grinders, and surface grinders in both production shops and maintenance environments. Material applications include 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The coarse 46-grit specification targets high material removal rates rather than finish grinding. It is typically installed and dressed by machinists or tool-and-die professionals working with horizontal-spindle surface grinders handling large workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive, Series 32A vitrified bond for stable, controlled breakdown\u003c\/li\u003e\n  \u003cli\u003e46 grit coarse grade optimized for high material removal rate\u003c\/li\u003e\n  \u003cli\u003eMedium hardness (code I) balances grain retention with self-dressing action\u003c\/li\u003e\n  \u003cli\u003eRated to 2320 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eNon-porous, non-tapered Type 1 straight-wheel profile with no recess\u003c\/li\u003e\n  \u003cli\u003eCompatible material range covers stainless, carbon steels, tool steels, aluminum, and cast iron grades\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CNC cutting tool machines, cylindrical grinders, and surface grinders.

Before mounting, power down and lockout the grinder per OSHA lockout\/tagout procedures and inspect the wheel for cracks or chips using the ring test. The wheel must be mounted with proper flanges and blotters per ANSI B7.1 standards and must never be operated above its rated maximum RPM. Dress the wheel before initial use to true the face and expose fresh abrasive grain.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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, No Recess)\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\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\u003eHole Size\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 46\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: I (Medium)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 2320\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Blue \/ Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 46I8V32A\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: 66253246803\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51543004152114,"sku":"66253246803","price":215.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6c3ae926d4bfb0a044edf66b3be36f21.jpg?v=1785913465","url":"https:\/\/voomisupply.com\/products\/norton-66253246803-surface-grinding-wheel-46-grit-14-in","provider":"Voomi Supply","version":"1.0","type":"link"}
