Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rates and controlled breakdown on soft carbon steels, tool steels, and super alloys. It measures 7 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole. The 46-grit, H-hardness (coarse grade) specification makes it well suited for aggressive material removal where surface finish is secondary to stock removal rate. Maximum operating speed is 3,600 RPM.\u003c\/p\u003e\u003cp\u003eThis wheel is used in production and maintenance grinding applications involving surface grinders, cylindrical grinders, and CNC cutting tool machines. The white aluminum oxide, semi-friable construction self-dresses effectively, reducing heat buildup at the workpiece. It is the 38A Type 1 series from NORTON, a specification widely referenced in toolroom and production floor environments where consistent wheel behavior across multiple passes is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent, controlled cut\u003c\/li\u003e\n\u003cli\u003e46 grit, H hardness coarse grade for aggressive stock removal\u003c\/li\u003e\n\u003cli\u003eSemi-friable construction promotes self-dressing and reduces heat transfer\u003c\/li\u003e\n\u003cli\u003ePorous wheel structure supports coolant flow and chip clearance\u003c\/li\u003e\n\u003cli\u003eRated to 3,600 RPM maximum operating speed\u003c\/li\u003e\n\u003cli\u003eNo recess, no taper — standard flat Type 1 profile\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Before mounting, inspect the wheel for cracks using the ring test — a damaged wheel must never be installed. Power down and lock out the grinder before changing wheels. Never exceed the rated 3,600 RPM maximum speed marked for this wheel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries Specification\u003c\/strong\u003e: 38A46-HVBE\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\u003eGrit\u003c\/strong\u003e: 46\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3,600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: White\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: Yes\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: 1.59 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\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: 66252941023\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540566835506,"sku":"66252941023","price":79.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/64afae05f52c549871aae0c9131e46bb.jpg?v=1785858598","url":"https:\/\/voomisupply.com\/products\/norton-66252941023-surface-grinding-wheel-7in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
