The wheel measures 7 inches in diameter by 1\/2 inch thick with a 1-1\/4 inch arbor hole. It runs at a maximum of 3600 RPM and carries a 120-grit, fine-grade abrasive rated at hardness code K. The 38A aluminum oxide grain is semi-friable, meaning it fractures under load to expose fresh cutting edges, which helps maintain cut rate without excessive heat buildup on the workpiece. Weighing approximately 1.59 pounds, the wheel is compact enough for bench and surface grinding machines used in tool rooms and production shops.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for grinding soft carbon steels, tool steels, and super alloys. It is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. The vitrified bond provides a rigid, porous-free structure that holds abrasive grains firmly during high-precision passes, making it a dependable choice for flat surface work, sharpening HSS tooling, and finishing hardened steel components in both job shop and production environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e120-grit, fine-grade aluminum oxide abrasive for smooth surface finishes on ferrous materials\u003c\/li\u003e\n  \u003cli\u003eSemi-friable 38A grain continuously self-dresses to sustain cut efficiency and reduce glazing\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigid grain retention and consistent geometry throughout wheel life\u003c\/li\u003e\n  \u003cli\u003eType 1 flat wheel profile with no recess — straightforward mounting on standard arbors\u003c\/li\u003e\n  \u003cli\u003eRated to 3600 RPM maximum for safe operation on compatible surface and cylindrical grinders\u003c\/li\u003e\n  \u003cli\u003eWhite wheel color allows easy visual inspection for contamination or loading between uses\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 per standard procedure. Power down and lock out the machine before installing or removing the wheel. Never exceed the 3600 RPM maximum speed rating stamped on the wheel or listed in this specification.\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\u003eSeries\u003c\/strong\u003e: 38A Type 1\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: 120\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\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 Color\u003c\/strong\u003e: White\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\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\u003eSpecifications\u003c\/strong\u003e: 38A120-KVBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.59 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: 66252941175\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542964437298,"sku":"66252941175","price":89.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2612db459b51ff18c234ded39f44c36d.jpg?v=1785912424","url":"https:\/\/voomisupply.com\/products\/norton-66252941175-surface-grinding-wheel-120-grit-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
