Built with ceramic abrasive grain and a vitrified bond, it operates at a maximum of 1800 RPM and delivers consistent, cool cutting action across the full wheel face. At 14 inches in diameter, 1 inch thick, and with a 5 inch arbor hole, this wheel is sized for production-grade surface and cylindrical grinder spindles. The 60 grit, J hardness (medium grade) combination suits stock removal passes where controlled aggressiveness and wheel integrity under load both matter. Licensed trades and skilled machinists handle installation and dressing of wheels this size.\u003c\/p\u003e\n\u003cp\u003eThis wheel is rated for use on 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. It is designed to mount on CNC cutting tool machines, cylindrical grinders, and surface grinders. The porous, semi-friable ceramic structure allows the wheel to self-sharpen as it cuts, which helps maintain cut rate on hard, heat-sensitive workpiece materials. The blue vitrified wheel is non-tapered with no recess, conforming to the standard Type 1 flat wheel geometry.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic abrasive grain with vitrified bond for cool, free-cutting action on hard metals\u003c\/li\u003e\n  \u003cli\u003e60 grit, J hardness (medium grade) suited for aggressive stock removal passes\u003c\/li\u003e\n  \u003cli\u003ePorous, semi-friable structure promotes continuous self-sharpening under load\u003c\/li\u003e\n  \u003cli\u003eType 1 flat wheel geometry, no taper, no recess — standard mounting configuration\u003c\/li\u003e\n  \u003cli\u003eRated for stainless steels, tool steels, titanium, super alloys, and iron grades\u003c\/li\u003e\n  \u003cli\u003eMaximum operating speed of 1800 RPM\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 accepting a 14 inch diameter, 5 inch arbor hole, Type 1 flat wheel.

Always inspect the wheel for cracks or damage before mounting and perform a ring test per standard procedure. Power down and lock out the machine before changing wheels. Never exceed the 1800 RPM maximum operating speed marked on the wheel.\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\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: J\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: 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 1800\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFriable\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\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\u003eSeries\u003c\/strong\u003e: 5SG Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 5SG60-JVS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 11.47 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: 66253363975\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540837204274,"sku":"66253363975","price":750.13,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9ac7135d66b7defcd4840cfbc3e89a54.jpg?v=1785864611","url":"https:\/\/voomisupply.com\/products\/norton-66253363975-surface-grinding-wheel-14in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
