Built with aluminum oxide abrasive and a vitrified bond, this wheel carries a coarse 46 grit rating and an H hardness code, placing it in the soft-to-medium hardness range for efficient, cool cutting. It measures 7 inches in diameter, 1\/2 inch thick, and features a 1-1\/4 inch arbor hole. The vitrified bond structure is porous, promoting chip clearance and reduced heat buildup during wet or dry operation. This wheel is installed and dressed by qualified grinding machine operators and surface grinder technicians.\u003c\/p\u003e\u003cp\u003eThis grinding wheel is suited for surface grinding, cylindrical grinding, and CNC cutting tool machine applications. It is rated for soft carbon steels, tool steels, and super alloys, making it a practical choice for tool rooms, production grinding cells, and maintenance shops. The 25A series designation indicates a pink aluminum oxide grain that is semi-friable, allowing the wheel to self-sharpen as it wears. It supports both wet and dry grinding operations, giving operators flexibility across different machine setups and coolant configurations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive grain, semi-friable, for consistent cut rate on steels and super alloys\u003c\/li\u003e\n\u003cli\u003eVitrified bond with porous structure promotes chip clearance and reduces heat at the workpiece\u003c\/li\u003e\n\u003cli\u003e46 grit coarse grade for aggressive stock removal\u003c\/li\u003e\n\u003cli\u003eH hardness code for efficient grinding on softer workpiece materials\u003c\/li\u003e\n\u003cli\u003eRated for wet and dry operation\u003c\/li\u003e\n\u003cli\u003eNo recess, no taper — standard Type 1 flat wheel profile\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.

Always power down and lock out the grinder before mounting or removing the wheel. Perform a ring test before installation to check for cracks, and never exceed the rated maximum speed of 3600 RPM. Use the correct flange and blotter assembly for the arbor size, and allow the wheel to run at operating speed in a guarded position before bringing it to the workpiece.\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\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\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\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Pink\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriable\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWet\/Dry Operation\u003c\/strong\u003e: Wet and Dry\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\u003eSeries\u003c\/strong\u003e: 25A Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecifications\u003c\/strong\u003e: 25A46-HVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.47 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: 69936662909\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541820899634,"sku":"69936662909","price":80.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d1d1b2f8c6e6b9fd3eb4809962878e65.jpg?v=1785885844","url":"https:\/\/voomisupply.com\/products\/norton-69936662909-surface-grinding-wheel-46-grit-7in","provider":"Voomi Supply","version":"1.0","type":"link"}
