It measures 14 inches in diameter, 1 inch thick, with a 5-inch arbor hole. The wheel is constructed from aluminum oxide abrasive bonded with a vitrified bond system, producing a coarse, semi-friable cutting action suited to softer ferrous metals and high-performance alloys. Rated at a maximum of 1800 RPM, it carries an H hardness code, placing it in the soft-to-medium range of the hardness scale. Specification designation is 38A46-HVBE. Total unit weight is 11.46 pounds.\u003c\/p\u003e\u003cp\u003eThis wheel is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in industrial and commercial shop environments. The aluminum oxide grain and coarse 46-grit structure make it well suited for soft carbon steels, tool steels, and super alloys where aggressive material removal is required without loading the wheel face. It is a non-tapered, non-recessed, non-porous Type 1 flat wheel compatible with machines that accept a 5-inch bore arbor at or below 1800 RPM.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent, open cutting action\u003c\/li\u003e\n\u003cli\u003e46 grit coarse grade for aggressive stock removal on ferrous metals and super alloys\u003c\/li\u003e\n\u003cli\u003eH hardness code — soft-to-medium wheel hardness suitable for harder workpiece materials\u003c\/li\u003e\n\u003cli\u003eSemi-friable grain structure self-sharpens during use to maintain cutting efficiency\u003c\/li\u003e\n\u003cli\u003eNon-porous, non-recessed Type 1 flat profile for surface and cylindrical grinding setups\u003c\/li\u003e\n\u003cli\u003eSeries 38A Type 1 designation with specification code 38A46-HVBE\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.

Always inspect the wheel for cracks or chips before mounting and perform a ring test. Power down and lock out the grinder before changing wheels, and verify that the machine spindle speed does not exceed the 1800 RPM maximum rating stamped on the wheel. Use correct flange hardware rated for the wheel diameter and arbor size.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size (Arbor Bore)\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: H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Soft\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\u003eFriability\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\u003eWheel Color\u003c\/strong\u003e: White\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\u003eMaximum RPM\u003c\/strong\u003e: 1800\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 38A46-HVBE\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: 66253364043\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541767192882,"sku":"66253364043","price":378.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cdfb0e32c9d0fd892a90645e91288cd5.jpg?v=1785884440","url":"https:\/\/voomisupply.com\/products\/norton-66253364043-surface-grinding-wheel-14in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
