Built on a vitrified bond with a ceramic (seeded gel) abrasive grain, this wheel operates at a maximum of 1800 RPM and delivers consistent stock removal on hard, difficult-to-grind materials. At 14 inches in diameter and 1.5 inches thick, with a 5-inch arbor hole, it is sized for industrial surface grinders and cylindrical grinders. The 60-grit, K-hardness (medium) structure provides a balance of aggressive cut rate and controlled surface finish. Licensed grinding professionals and tool room machinists are the primary installers of this wheel.\u003c\/p\u003e\n\u003cp\u003eThis wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in production and tool room environments. It is well suited for material applications including 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. The porous, semi-friable grain structure allows the wheel to remain free-cutting through extended runs on these tough materials, making it a practical choice for shops handling mixed ferrous and specialty alloy work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic abrasive grain — semi-friable, self-sharpening for consistent cut on hard alloys\u003c\/li\u003e\n  \u003cli\u003eVitrified bond with porous structure promotes coolant flow and reduces heat buildup\u003c\/li\u003e\n  \u003cli\u003e60 grit, K hardness (medium grade) balances material removal rate with surface finish quality\u003c\/li\u003e\n  \u003cli\u003eType 1 flat wheel profile — no recess, no taper — fits standard surface and cylindrical grinder flanges\u003c\/li\u003e\n  \u003cli\u003eRated to 1800 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003e5SG series specification (5SG60-KVS) for traceability and replacement matching\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eSpecified for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always perform a ring test before mounting and inspect the wheel for cracks or damage. Never exceed the 1800 RPM maximum rated speed; verify the machine spindle speed before operation. Use properly sized blotter pads and flanges, and allow the wheel to run at operating speed for at least one minute behind a guard before presenting workpiece contact.\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: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Hole 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: 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\u003eSeries Specification\u003c\/strong\u003e: 5SG60-KVS\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\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\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: 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: 66253302160\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538860572978,"sku":"66253302160","price":1098.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/67d3ec48ffd930e1f4073f5cb7b5bc20.jpg?v=1785828475","url":"https:\/\/voomisupply.com\/products\/norton-66253302160-surface-grinding-wheel-60-grit-14-in","provider":"Voomi Supply","version":"1.0","type":"link"}
