It measures 6 inches in diameter and 1\/4 inch thick with a 1-1\/4 inch arbor hole. The abrasive is aluminum oxide with a vitrified bond, rated at medium hardness (K hardness code) and semi-friable grain structure. Maximum operating speed is 4140 RPM. The 38A Series designation identifies this as a white aluminum oxide wheel optimized for consistent stock removal and controlled heat generation during dry or wet grinding operations.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding, cylindrical grinding, and use on CNC cutting tool machines. It is commonly applied to soft carbon steels, tool steels, and super alloys where controlled abrasion and wheel breakdown rate are critical to finish quality and workpiece integrity. The non-porous, non-tapered, non-recessed profile makes it a direct fit for standard surface grinder spindle setups encountered in tool rooms and production grinding cells.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive (38A Series) for use on carbon steels, tool steels, and super alloys\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigid support and consistent grit exposure throughout wheel life\u003c\/li\u003e\n\u003cli\u003eMedium grade (K hardness) semi-friable grain self-dresses for controlled stock removal\u003c\/li\u003e\n\u003cli\u003e60 grit delivers a balance of aggressive cutting and acceptable surface finish\u003c\/li\u003e\n\u003cli\u003eNon-porous, non-tapered, no-recess Type 1 profile for straightforward spindle mounting\u003c\/li\u003e\n\u003cli\u003eRated to 4140 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.

Always inspect the wheel for cracks or chips using the ring test before mounting. Power down and lock out the grinder before changing wheels, and confirm the machine RPM rating meets or exceeds the wheel's 4140 RPM maximum before use. Use appropriate flanges and blotters when mounting; never exceed the rated maximum speed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.25 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 Type\u003c\/strong\u003e: Type 1\u003c\/li\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\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\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\u003eWheel Color\u003c\/strong\u003e: White\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\u003eMaximum RPM\u003c\/strong\u003e: 4140\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\u003eFor Use With\u003c\/strong\u003e: CNC Cutting Tool Machine, Cylindrical Grinder, Surface Grinder\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecifications\u003c\/strong\u003e: 38A60-KVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.58 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: 66252835803\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51544098767154,"sku":"66252835803","price":64.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0f2ac80722be2427e70f8176bf648040.jpg?v=1785924132","url":"https:\/\/voomisupply.com\/products\/norton-66252835803-surface-grinding-wheel-60-grit-6-in","provider":"Voomi Supply","version":"1.0","type":"link"}
