Constructed from aluminum oxide abrasive in a vitrified bond, this wheel delivers consistent cutting action and thermal stability across extended grinding cycles. The coarse 46 grit and K hardness rating (medium) make it well suited for aggressive material removal where surface finish is secondary to throughput. Rated at a maximum of 1800 RPM, the wheel measures 14 inches in diameter, 1 inch thick, with a 5-inch arbor hole. Installation and operation require a compatible spindle and guarding setup rated for the wheel dimensions.\u003c\/p\u003e\u003cp\u003eThis wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in professional shop environments. The 38A Series aluminum oxide formulation is a standard choice for grinding soft carbon steels, tool steels, and super alloys where wheel life and cut rate need to stay balanced. The non-porous, non-tapered, non-recessed profile fits standard Type 1 mounting configurations. Shops running high-volume tool reconditioning or surface prep on structural components will find the coarse grit appropriate for roughing passes before finish grinding operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e46 grit coarse aluminum oxide abrasive for aggressive stock removal\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigidity and thermal resistance during dry or wet grinding\u003c\/li\u003e\n\u003cli\u003eK hardness (medium) rating balances wheel wear against cutting efficiency\u003c\/li\u003e\n\u003cli\u003eSemi-friable abrasive exposes fresh cutting edges as the wheel wears\u003c\/li\u003e\n\u003cli\u003eType 1 flat profile with no recess and no taper for straightforward mounting\u003c\/li\u003e\n\u003cli\u003eCompatible with surface grinders, cylindrical grinders, and CNC tool machines\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eSuitable for use on CNC cutting tool machines, cylindrical grinders, and surface grinders.

Power down and lock out the machine before mounting or removing any grinding wheel. Inspect the wheel for cracks or chips using the ring test before mounting, and never exceed the 1800 RPM maximum speed rating. Ensure the machine spindle, flanges, and guards are rated for a 14-inch diameter wheel before operation.\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: 38A Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 38A46-KVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1\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 inch\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: 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: K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriable\u003c\/strong\u003e: Semi-Friable\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: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 1800\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Soft Carbon Steels, Tool Steels, Super Alloys\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11.46 pounds\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: 66253364049\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540565328178,"sku":"66253364049","price":393.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2523c53d1aa696c04f5ba1ab9a8c5f21.jpg?v=1785858549","url":"https:\/\/voomisupply.com\/products\/norton-66253364049-surface-grinding-wheel-14in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
