It measures 14 inches in diameter, 2 inches thick, with a 5-inch hole and a one-side recess of 0.5 inches at 8 inches diameter. The abrasive is aluminum oxide with a vitrified bond, rated at 60 grit and H hardness code (medium grade). The wheel carries a maximum operating speed of 2320 RPM. At 11.93 pounds, it is sized for industrial-grade surface and cylindrical grinders. The 38A series designation indicates a semi-friable, white aluminum oxide grain structure suited to precision grinding applications where heat control matters.\u003c\/p\u003e\u003cp\u003eThis wheel is intended for use on surface grinders and cylindrical grinders in both production and toolroom environments. Typical applications include finish and rough grinding of soft carbon steels, tool steels, and super alloys. The medium grade and 60 grit combination makes it a practical choice for operators balancing stock removal rate with surface finish quality. It is installed and dressed by grinding machine operators and toolroom machinists working with stationary grinder setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 5 recessed wheel with one-side recess at 8 inches diameter and 0.5 inches depth for clearance in recessed-hub applications\u003c\/li\u003e\n\u003cli\u003e38A aluminum oxide grain — semi-friable, white, suited to heat-sensitive materials and precision tolerances\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigidity and porosity for consistent chip clearance during grinding\u003c\/li\u003e\n\u003cli\u003e60 grit medium grade balances aggressive stock removal with acceptable surface finish\u003c\/li\u003e\n\u003cli\u003eH hardness code (soft hardness rating) promotes self-dressing action on harder workpiece materials\u003c\/li\u003e\n\u003cli\u003eRated to 2320 RPM maximum operating speed\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with surface grinders and cylindrical grinders.

Always inspect the wheel for cracks or chips before mounting and perform a ring test prior to installation. Power down and lock out the grinder before removing or installing any wheel. Never exceed the maximum operating speed of 2320 RPM marked on the wheel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 38A Type 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 38A60-HVP2\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 Color\u003c\/strong\u003e: White\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\u003eHardness Rating\u003c\/strong\u003e: Soft\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: Yes\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: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: One-Side\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Diameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Depth\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 2320\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11.93 pounds\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\u003eFor Use With\u003c\/strong\u003e: Cylindrical Grinder, Surface Grinder\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: 66253319951\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540884128050,"sku":"66253319951","price":597.26,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3f27e0f8c2e0730926f3ba198724e06b.jpg?v=1785865410","url":"https:\/\/voomisupply.com\/products\/norton-66253319951-surface-grinding-wheel-14in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
