Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rates and thermal stability across demanding grinding cycles. It measures 8 inches in diameter, 1\/4 inch thick, with a 1-1\/4 inch arbor hole, and is rated to a maximum of 3600 RPM. The 60-grit, K-hardness (medium grade) specification makes it well suited for stock removal applications where surface finish and wheel longevity must both be maintained. It weighs approximately 1.05 pounds and ships as a single unit.\u003c\/p\u003e\n\u003cp\u003eThis wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in both job shop and production environments. It is a standard Type 1 straight wheel with no recess and no taper, fitting conventional spindle setups without modification. Typical users include tool-and-die makers, machinists, and grinding specialists working with ferrous materials. The semi-friable aluminum oxide grain continuously self-sharpens to sustain cutting action through extended runs on hard-to-grind materials including tool steels and super alloys.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive — semi-friable grain self-sharpens for consistent stock removal\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigidity and thermal resistance during wet or dry grinding\u003c\/li\u003e\n  \u003cli\u003e60 grit, K hardness (medium grade) balances aggressive cut rate with controlled wheel wear\u003c\/li\u003e\n  \u003cli\u003eRated to 3600 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eType 1 straight profile with no recess and no taper — fits standard surface grinder spindles\u003c\/li\u003e\n  \u003cli\u003eNon-porous wheel construction for uniform abrasive density across the full face\u003c\/li\u003e\n  \u003cli\u003eSeries designation 38A60-KVBE for direct OEM and MRO cross-reference\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Before mounting, inspect the wheel for cracks or chips using the ring test — do not mount a damaged wheel. Ensure the machine spindle speed does not exceed the 3600 RPM maximum rating stamped on the wheel. Use proper flanges and blotters, and run the wheel at operating speed with the guard in place for at least one minute before bringing it into contact with the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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 Type 1 (38A60-KVBE)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 8 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\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\u003eMaximum RPM\u003c\/strong\u003e: 3600\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: Non-Porous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: White\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\u003eWeight\u003c\/strong\u003e: 1.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 66253010825\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539192611122,"sku":"66253010825","price":77.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/667c3aee86a6cd0d259815cf91ee9368.jpg?v=1785836329","url":"https:\/\/voomisupply.com\/products\/norton-66253010825-surface-grinding-wheel-8in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
