Built with a ceramic abrasive grain and a vitrified bond, this wheel delivers consistent stock removal and dimensional control on difficult-to-grind materials. It measures 14 inches in diameter, 1 inch thick, with a 5-inch arbor hole, and is rated for a maximum speed of 1800 RPM. At 17 pounds, this is a full-size wheel suited to production-grade surface and cylindrical grinding equipment. The K hardness code indicates a medium-grade bond that balances wheel life against cutting action across a wide range of ferrous and exotic alloys.\u003c\/p\u003e\n\u003cp\u003eThis wheel is designed for grinding 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. It is intended for use on CNC cutting tool machines, cylindrical grinders, and surface grinders in industrial and toolroom environments. The semi-friable ceramic grain continuously fractures to expose fresh cutting edges, making it well suited for heat-sensitive materials and applications where surface finish and geometry tolerances are tight. Machinists, tool grinders, and grinding technicians working in job shops, aerospace, and heavy manufacturing are the primary installers and operators.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic abrasive grain for aggressive, cool cutting on hard and exotic alloys\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigidity and consistent form-holding under heavy cuts\u003c\/li\u003e\n  \u003cli\u003eType 1 straight wheel profile fits standard surface and cylindrical grinder spindles with 5-inch arbor holes\u003c\/li\u003e\n  \u003cli\u003eK hardness (medium grade) balances wheel life and self-dressing action\u003c\/li\u003e\n  \u003cli\u003eSemi-friable grain structure reduces heat buildup on heat-sensitive workpieces such as titanium and tool steels\u003c\/li\u003e\n  \u003cli\u003eRated to 1800 RPM for safe operation on production grinding equipment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with CNC cutting tool machines, cylindrical grinders, and surface grinders requiring a Type 1 straight wheel with a 14-inch diameter, 5-inch arbor hole, and 1800 RPM maximum operating speed.

Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation using the ring test, and never exceed the rated maximum RPM of 1800. Allow the wheel to run at operating speed for at least one minute in a guarded position 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\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\u003eArbor Hole Size\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 (Straight)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 1800\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic\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: Blue\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5SG Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecifications\u003c\/strong\u003e: 5SG80-KVS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 17 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: 66253364003\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541484044594,"sku":"66253364003","price":749.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0ac5633bda3df9012ae2622508194405.jpg?v=1785877469","url":"https:\/\/voomisupply.com\/products\/norton-66253364003-surface-grinding-wheel-80-grit-14-in","provider":"Voomi Supply","version":"1.0","type":"link"}
