Constructed with aluminum oxide abrasive and a vitrified bond, it delivers consistent stock removal with controlled wear. The wheel measures 14 inches in diameter, 1 inch thick, with a 5-inch arbor hole. It carries a 60 grit rating and K hardness code, placing it in the medium grade range. Rated at a maximum of 1800 RPM, this wheel is sized for production-level surface grinders and is installed by machinists and grinding professionals in tool rooms and manufacturing environments.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding operations on soft carbon steels, tool steels, and super alloys. It is designed for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. The 38A series aluminum oxide grain is semi-friable, meaning it fractures under load to expose fresh cutting edges, which supports cooler grinding action and longer wheel life on ferrous workpieces. It is a non-tapered, non-recessed Type 1 flat wheel with a white wheel color for easy visual wear inspection.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 1 flat wheel profile with no recess and no taper for straightforward surface grinding setups\u003c\/li\u003e\n\u003cli\u003e60 grit, K hardness (medium grade) for balanced material removal and surface finish on steel and alloys\u003c\/li\u003e\n\u003cli\u003eSemi-friable aluminum oxide grain refreshes cutting edges during use, reducing heat buildup\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigidity and consistent performance across the wheel face\u003c\/li\u003e\n\u003cli\u003eMaximum operating speed of 1800 RPM — do not exceed this rating\u003c\/li\u003e\n\u003cli\u003eWhite wheel color for easy visual inspection of wear and loading\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always power down and lock out the machine before mounting or dismounting a grinding wheel. Inspect the wheel for cracks or chips using the ring test prior to mounting, and use proper blotters and flanges as required by the machine manufacturer. Never exceed the maximum operating speed of 1800 RPM marked on the wheel or its packaging.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 5 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\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 1800\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\u003eSeries\u003c\/strong\u003e: 38A\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: 11.46 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: 66253364053\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542449357106,"sku":"66253364053","price":322.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bec1c0b2bb6c066fc28cc25457264b5f.jpg?v=1785900862","url":"https:\/\/voomisupply.com\/products\/norton-66253364053-surface-grinding-wheel-14in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
