Built on a vitrified bond with 80-grit aluminum oxide abrasive, this wheel delivers consistent cut rates and predictable wear across high-cycle grinding operations. It measures 8 inches in diameter, 0.5 inches thick, with a 1-1\/4 inch arbor hole, and carries a J hardness code (medium grade). The 38A series designation indicates a semi-friable aluminum oxide grain suited to applications requiring a sharp, self-dressing cutting action. Maximum operating speed is 3,600 RPM.\u003c\/p\u003e\n\u003cp\u003eThis wheel is rated for use on soft carbon steels, tool steels, and super alloys. It is a standard fit for surface grinders, cylindrical grinders, and CNC cutting tool machines in production and tool-room environments. The medium-grade, non-porous, vitrified matrix holds its form well under moderate grinding pressures, making it a practical choice for flat surface finishing and tool reconditioning work in both job-shop and industrial settings.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e80-grit aluminum oxide abrasive for moderate material removal with good surface finish\u003c\/li\u003e\n  \u003cli\u003eJ hardness code, medium grade, vitrified bond for consistent wheel wear and form retention\u003c\/li\u003e\n  \u003cli\u003eType 1 straight wheel profile, no recess, non-tapered for standard surface and cylindrical grinder spindles\u003c\/li\u003e\n  \u003cli\u003eSemi-friable grain structure promotes self-dressing action on tool steels and super alloys\u003c\/li\u003e\n  \u003cli\u003eRated to 3,600 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eWhite wheel color for visual wear monitoring during use\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.

Always inspect the wheel for cracks or chips before mounting and perform a ring test. Power down and de-energize the machine completely before mounting or dismounting the wheel. Never exceed the rated maximum speed of 3,600 RPM; verify machine spindle speed before operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\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 (Straight)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 38A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecifications Code\u003c\/strong\u003e: 38A80-JVBE\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\u003eMaximum RPM\u003c\/strong\u003e: 3,600\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: 2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\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: 66253013787\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541166522674,"sku":"66253013787","price":81.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/634061c8e22b3f476893d8c57a423d3e.jpg?v=1785869341","url":"https:\/\/voomisupply.com\/products\/norton-66253013787-surface-grinding-wheel-80-grit-type-1","provider":"Voomi Supply","version":"1.0","type":"link"}
