Built with aluminum oxide abrasive in a vitrified bond, this wheel carries an 80 grit rating and K hardness code, placing it in the medium grade range. It measures 14 inches in diameter, 1 inch thick, and carries a 5-inch arbor hole. The wheel is rated to a maximum of 1800 RPM and is classified as semi-friable, meaning it fractures gradually to expose fresh cutting grain during use. It is intended for installation and operation by skilled machinists and grinding technicians.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for wet or dry surface grinding applications on soft carbon steels, tool steels, and super alloys. It fits surface grinders, cylindrical grinders, and CNC cutting tool machines. The 38A series vitrified aluminum oxide construction makes it a standard choice in tool-room and production grinding environments where consistent finish and wheel life are priorities. At 11.46 pounds, the wheel mass is appropriate for large-diameter surface grinding operations requiring stable, controlled material removal.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive with vitrified bond for controlled, consistent cutting action\u003c\/li\u003e\n  \u003cli\u003e80 grit, K hardness (medium grade) for balanced stock removal and surface finish on steels and alloys\u003c\/li\u003e\n  \u003cli\u003eSemi-friable construction exposes fresh abrasive grain progressively during grinding\u003c\/li\u003e\n  \u003cli\u003eType 1 flat wheel profile with no recess and non-tapered sides\u003c\/li\u003e\n  \u003cli\u003e5-inch arbor hole fits standard large surface grinder and cylindrical grinder spindles\u003c\/li\u003e\n  \u003cli\u003e38A series specification (38A80-KVBE) for consistent lot-to-lot performance\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 using the ring test before mounting, and never exceed the rated maximum speed of 1800 RPM. Guard the wheel per machine manufacturer requirements and dress the wheel face before the first pass after installation. Power down and lock out the grinder before changing or adjusting the wheel.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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\u003eArbor Hole Size\u003c\/strong\u003e: 5 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: K\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFriability\u003c\/strong\u003e: Semi-Friable\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\u003eSeries Specification\u003c\/strong\u003e: 38A80-KVBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11.46 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: 66253364058\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542392734002,"sku":"66253364058","price":371.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6d1ff08d15180ea1c0b9693c7a9cd2d0.jpg?v=1785899509","url":"https:\/\/voomisupply.com\/products\/norton-66253364058-surface-grinding-wheel-80-grit-14in","provider":"Voomi Supply","version":"1.0","type":"link"}
