Built around a white aluminum oxide abrasive grain with a vitrified bond, it delivers consistent stock removal and finish quality on production surface grinders and cylindrical grinders. The wheel measures 12 inches in diameter, 1 inch thick, with a 3-inch arbor hole. At 60 grit and an H hardness code (medium grade, semi-friable), it balances cut rate with controlled wear, making it a reliable choice for licensed toolroom machinists and grinding specialists working in job shops or industrial maintenance environments.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding operations on a range of ferrous workpiece materials including soft carbon steels, tool steels, and super alloys. It is compatible with CNC cutting tool machines, cylindrical grinders, and surface grinders. The non-tapered, non-recessed Type 1 flat wheel profile fits standard spindle setups common in both manual and CNC grinding cells. The 38A series designation identifies it as a Norton aluminum oxide product line recognized across industrial toolroom and production grinding applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eWhite aluminum oxide abrasive for consistent cut on steels and super alloys\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigid grain support and open structure for efficient chip clearance\u003c\/li\u003e\n\u003cli\u003e60 grit, H hardness (medium grade) balances stock removal rate with wheel life\u003c\/li\u003e\n\u003cli\u003eSemi-friable grain fractures to expose fresh cutting edges during use\u003c\/li\u003e\n\u003cli\u003eNon-porous, non-tapered, no-recess Type 1 flat wheel profile for broad spindle compatibility\u003c\/li\u003e\n\u003cli\u003eRated to 2070 RPM maximum operating speed\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 requiring a Type 1 flat wheel with a 3-inch arbor hole and 12-inch diameter.

Always power down and lock out 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 2070 RPM maximum speed rating. Use flanges and blotters appropriate for the wheel size and arbor as specified by the machine manufacturer.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eArbor Hole Size\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: H\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriability\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorosity\u003c\/strong\u003e: Non-Porous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 (No Recess, No Taper)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 2070\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 38A Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 38A60-HVBE\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: 9.045 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: 66253262711\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539130450226,"sku":"66253262711","price":284.24,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/393af81d043481a411c8eba21c61ed2a.jpg?v=1785835089","url":"https:\/\/voomisupply.com\/products\/norton-66253262711-surface-grinding-wheel-60-grit-12-in","provider":"Voomi Supply","version":"1.0","type":"link"}
