Built with a ceramic abrasive grain and a vitrified bond, this wheel delivers consistent stock removal and long wheel life on hard-to-grind materials. It measures 10 inches in diameter, 1 inch thick, with a 3-inch arbor hole, and carries a coarse 46 grit rating with a J hardness code. The semi-friable ceramic grain continuously self-sharpens under load, reducing heat buildup and glazing. Licensed HVAC techs and machinists working with tool steels or exotic alloys will find this wheel well-suited to production surface and cylindrical grinding applications.\u003c\/p\u003e\u003cp\u003eThis grinding wheel is intended for use on CNC cutting tool machines, cylindrical grinders, and surface grinders. It is rated for material applications including 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. The blue vitrified wheel is porous in structure, which supports coolant flow and chip clearance during wet or dry grinding operations. It is a single-piece, no-recess, straight wheel with no taper, making it a direct fit for standard surface grinder arbor setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic abrasive grain with semi-friable structure for continuous self-sharpening\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigidity and dimensional stability at operating speed\u003c\/li\u003e\n\u003cli\u003eCoarse 46 grit, J hardness (medium wheel hardness) for aggressive stock removal\u003c\/li\u003e\n\u003cli\u003ePorous wheel structure supports coolant flow and chip evacuation\u003c\/li\u003e\n\u003cli\u003eRated for a wide range of ferrous and exotic alloy materials including titanium and super alloys\u003c\/li\u003e\n\u003cli\u003eStraight Type 1 profile, no recess, no taper — compatible with standard arbor setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CNC cutting tool machines, cylindrical grinders, and surface grinders.

Always inspect the wheel for cracks or chips using a ring test before mounting, and confirm the machine spindle speed does not exceed the rated maximum RPM. Power down and lock out the grinder before changing wheels. Never force a wheel onto an arbor or alter the bore diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 10 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\u003eGrit\u003c\/strong\u003e: 46\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: J\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Medium\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\u003eWheel Type\u003c\/strong\u003e: Type 1 (Straight)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: 5SG46-JVS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5SG Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 2485\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Blue\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: Yes\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\u003eMaterial Application\u003c\/strong\u003e: 400 Series Stainless, Hard Carbon Steels, Tool Steels, Titanium, Super Alloys, Cast Iron, Ductile Iron, Gray Iron\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: 66253160401\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542080225586,"sku":"66253160401","price":438.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e9ed868c6fbbf0ea574bc61eed6a6592.jpg?v=1785891429","url":"https:\/\/voomisupply.com\/products\/norton-66253160401-surface-grinding-wheel-10in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
