Built to the 5SG specification with a vitrified bond, this wheel measures 12 inches in diameter, 1 inch thick, with a 3-inch arbor hole. The 60-grit, K-hardness (medium) structure delivers a balance of cut rate and wheel life suited to production surface and cylindrical grinding. The semi-friable ceramic abrasive continuously fractures to expose fresh cutting edges, reducing heat buildup and extending dress intervals. Licensed trade professionals and industrial grinding specialists are the primary installers and operators of this wheel.\u003c\/p\u003e\u003cp\u003eThis wheel is designed for demanding applications involving 400 Series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. It is rated for use on CNC cutting tool machines, cylindrical grinders, and surface grinders. The porous, vitrified-bond construction supports coolant penetration, making it well suited to wet-grinding setups where thermal management is critical. The non-tapered, no-recess Type 1 flat profile fits standard 3-inch arbor spindles common on industrial surface grinders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic abrasive grain (5SG series) with semi-friable fracture pattern for consistent cut rate\u003c\/li\u003e\n\u003cli\u003eVitrified bond with open, porous structure supports coolant flow and chip clearance\u003c\/li\u003e\n\u003cli\u003e60 grit, K hardness (medium) for balanced stock removal and wheel life\u003c\/li\u003e\n\u003cli\u003eType 1 flat wheel, no recess, no taper — fits standard 3-inch arbor spindles\u003c\/li\u003e\n\u003cli\u003eRated for 400 Series stainless, tool steels, titanium, super alloys, and cast and ductile iron\u003c\/li\u003e\n\u003cli\u003eMaximum operating speed of 2,070 RPM\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 requiring a Type 1 flat wheel with a 3-inch arbor hole and a maximum speed rating of 2,070 RPM.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGrinding wheel mounting must be performed by a qualified operator following ANSI B11.9 and OSHA 29 CFR 1910.215 standards. Always ring-test the wheel before mounting and inspect for cracks or chips. Power down and lock out the grinder before changing wheels. Never exceed the maximum operating speed of 2,070 RPM marked on the wheel or its blotter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 (Flat, No Recess)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic (Semi-Friable)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries \/ Specification\u003c\/strong\u003e: 5SG60-KVS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 12 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: 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\u003eMaximum RPM\u003c\/strong\u003e: 2,070\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Blue\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\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\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: 66253262505\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541779546418,"sku":"66253262505","price":618.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6c2f602096ffb59cacd7fd4eeb47e34e.jpg?v=1785884728","url":"https:\/\/voomisupply.com\/products\/norton-66253262505-surface-grinding-wheel-60-grit-12in","provider":"Voomi Supply","version":"1.0","type":"link"}
