Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent stock removal and profile retention across extended grinding cycles. It measures 10 inches in diameter, 1\/4 inches thick, and accepts a 3-inch arbor hole. The 80-grit, K-hardness (medium grade) specification targets applications where controlled surface finish and dimensional accuracy are required. The semi-friable aluminum oxide grain self-sharpens under load, reducing heat buildup at the workpiece surface. Rated at a maximum of 2,485 RPM, this wheel is well-suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines.\u003c\/p\u003e\n\u003cp\u003eThis grinding wheel is designed for use on soft carbon steels, tool steels, and super alloys. Its medium hardness and 80-grit structure make it appropriate for general surface grinding where moderate material removal and reasonable surface finish are both priorities. The 3-inch center hole fits standard surface grinder spindles, and the Type 1 straight-wheel profile suits flat surface and cylindrical OD grinding operations in production and tool room environments alike. The white aluminum oxide wheel color indicates a friability level suited to heat-sensitive workpieces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive with semi-friable grain for self-sharpening under load\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigidity and consistent form-holding during grinding\u003c\/li\u003e\n  \u003cli\u003e80 grit, K hardness (medium grade) balances stock removal with surface finish quality\u003c\/li\u003e\n  \u003cli\u003eType 1 straight-wheel profile fits surface grinders, cylindrical grinders, and CNC tool machines\u003c\/li\u003e\n  \u003cli\u003eNon-tapered, no-recess design for straightforward mounting on standard 3-inch arbors\u003c\/li\u003e\n  \u003cli\u003eSeries 38A Type 1 specification (38A80-KVBE) for consistent grade-to-grade repeatability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always power down and de-energize the machine before mounting or removing a wheel. Inspect the wheel for cracks or chips before each installation using the ring test, and never exceed the rated maximum of 2,485 RPM. Use proper flanges and blotters as recommended by the machine manufacturer.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 (Straight)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 3 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\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: 2,485\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\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\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\u003eMaterial Application\u003c\/strong\u003e: Soft Carbon Steels, Tool Steels, Super Alloys\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.53 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: 66253149572\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542348497202,"sku":"66253149572","price":107.91,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e9d4fef4c7186e6dc428e6c12ae99508.jpg?v=1785898693","url":"https:\/\/voomisupply.com\/products\/norton-66253149572-surface-grinding-wheel-80-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
