It measures 8 inches in diameter, 0.5 inches thick, with a 1.25-inch arbor hole. The wheel uses a ceramic abrasive grain bonded in a vitrified matrix, rated at a medium grade with a G hardness code. This combination supports consistent stock removal and extended wheel life on hard ferrous and exotic materials. Rated to 3,600 RPM maximum, it is suited for wet grinding operations on surface grinders and CNC tool grinding equipment. Machinists and tool grinders are the primary installers and operators of this wheel.\u003c\/p\u003e\u003cp\u003eThis wheel is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. The ceramic abrasive and porous structure make it 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. Its semi-friable grain continually fractures to expose fresh cutting edges, reducing heat buildup during tight-tolerance surface grinding passes. The purple wheel color is characteristic of the 3SG Series Type 1 profile.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic abrasive grain with vitrified bond for consistent cutting action and long wheel life\u003c\/li\u003e\n\u003cli\u003ePorous wheel structure supports wet grinding and efficient coolant flow\u003c\/li\u003e\n\u003cli\u003eSemi-friable grain self-dresses during use to maintain sharpness\u003c\/li\u003e\n\u003cli\u003eG hardness code and medium grade balance wheel wear against workpiece hardness\u003c\/li\u003e\n\u003cli\u003eType 1 straight wheel profile fits standard surface and cylindrical grinder 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\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always inspect the wheel for cracks or chips before mounting and perform a ring test. Power down and lock out the grinder before changing wheels. Never exceed the maximum spindle speed of 3,600 RPM marked on the wheel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 60\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: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3,600\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\u003eWheel Color\u003c\/strong\u003e: Purple\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriability\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation\u003c\/strong\u003e: Wet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3SG Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecifications\u003c\/strong\u003e: 3SGR60-GVP2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.8 pounds\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: 66253019347\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540120207666,"sku":"66253019347","price":182.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8cf084807d9931fb636acbe7cb3e84f0.jpg?v=1785846197","url":"https:\/\/voomisupply.com\/products\/norton-66253019347-surface-grinding-wheel-60-grit-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
