Built on an aluminum oxide abrasive with a vitrified bond, it delivers consistent cut rates and shape retention across high-cycle production runs. The wheel measures 7 inches in diameter, 0.5 inches thick, and accepts a 1.25-inch arbor hole. Rated to a maximum of 3,600 RPM, it carries an I hardness code and medium grade classification, making it well-suited for applications that demand controlled material removal without aggressive wheel breakdown. The 38A series designation identifies the semi-friable white aluminum oxide grain used in this wheel.\u003c\/p\u003e\u003cp\u003eThis wheel is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both job-shop and production environments. The vitrified bond resists heat and maintains form under repeated dressing cycles, which is critical when grinding tight-tolerance workpieces from tool steels or super alloys. Soft carbon steels also fall within its rated material applications, making it a versatile choice for shops that run mixed workloads. It is a non-porous, non-tapered, non-recessed Type 1 flat wheel with a white wheel color for easy wear monitoring.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e80 grit, medium grade aluminum oxide abrasive for controlled stock removal\u003c\/li\u003e\n\u003cli\u003eVitrified bond maintains wheel form and withstands dressing cycles\u003c\/li\u003e\n\u003cli\u003eSemi-friable 38A grain self-sharpens under load, extending cut life on hard materials\u003c\/li\u003e\n\u003cli\u003eNon-porous, non-recessed Type 1 flat profile fits standard surface and cylindrical grinder arbors\u003c\/li\u003e\n\u003cli\u003e3,600 RPM maximum speed rating for use on common bench and pedestal surface grinders\u003c\/li\u003e\n\u003cli\u003eRated for soft carbon steels, tool steels, and super alloys\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.

Disconnect and lock out power to the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the 3,600 RPM maximum speed rating stamped on the wheel. Always use the proper flanges and blotters specified for Type 1 wheels and allow the wheel to run at operating speed for at least one minute behind a guard before presenting work.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 7 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\u003eHole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\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: I\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\u003eSeries\u003c\/strong\u003e: 38A Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecifications\u003c\/strong\u003e: 38A80-IVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriable\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\u003eFor Use With\u003c\/strong\u003e: CNC Cutting Tool Machine, Cylindrical Grinder, Surface Grinder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.59 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: 66252941048\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542376513842,"sku":"66252941048","price":89.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f4bbfdf9079d39cf7a6523094e4a6534.jpg?v=1785898989","url":"https:\/\/voomisupply.com\/products\/norton-66252941048-surface-grinding-wheel-80-grit-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
