Built to the 38A series specification, it features a 60-grit, medium-grade abrasive structure with a K hardness code and a semi-friable grain that self-sharpens under load. The wheel measures 12 inches in diameter, 1 inch thick, with a 3-inch arbor hole, and carries a maximum operating speed of 2,070 RPM. At 9.04 pounds, it is suited for production surface grinding where consistent cut rate and wheel life are both priorities.\u003c\/p\u003e\u003cp\u003eThis wheel is rated for use on soft carbon steels, tool steels, and super alloys. It installs on surface grinders, cylindrical grinders, and CNC cutting tool machines. The non-porous, vitrified bond provides rigidity and precise form-holding, making it appropriate for flat-surface finishing work in job shops, tool rooms, and production grinding environments. Licensed machinists and toolroom grinders are the primary installers of wheels in this class.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e38A series aluminum oxide grain — semi-friable, self-sharpening under load\u003c\/li\u003e\n\u003cli\u003eVitrified bond for rigid, precise form retention\u003c\/li\u003e\n\u003cli\u003e60 grit, K hardness (medium grade) balanced for soft carbon steels, tool steels, and super alloys\u003c\/li\u003e\n\u003cli\u003eNon-porous, no-recess Type 1 flat wheel profile\u003c\/li\u003e\n\u003cli\u003eRated to 2,070 RPM maximum operating speed\u003c\/li\u003e\n\u003cli\u003eWhite wheel color for easy dressing inspection\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 3-inch arbor hole and a 12-inch diameter Type 1 wheel.

Always power down and lock out the machine before mounting or removing a wheel. Inspect the wheel for cracks or chips using the ring test before installation and never exceed the 2,070 RPM maximum speed marked on the wheel. Flanges, blotters, and mounting hardware must conform to ANSI B11.9 and the machine manufacturer's requirements.\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\u003eMaximum RPM\u003c\/strong\u003e: 2,070\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: K\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\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 (Flat, No Recess)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries Specification\u003c\/strong\u003e: 38A60-KVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriability\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9.04 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: 66253262718\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542520627506,"sku":"66253262718","price":294.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4218c0a3f326a8f8ea82824e24d8d004.jpg?v=1785902737","url":"https:\/\/voomisupply.com\/products\/norton-66253262718-surface-grinding-wheel-60-grit-12-in","provider":"Voomi Supply","version":"1.0","type":"link"}
