It measures 12 inches in diameter and 1.5 inches thick, with a 5-inch arbor hole and a one-side recess of 0.5 inches at a 7.5-inch recess diameter. The wheel uses a vitrified bond with 60 grit and an I hardness code, placing it in the medium grade range. At a maximum operating speed of 2070 RPM, it delivers controlled, consistent cut rates on demanding materials. Weighing 10.92 pounds, it is sized for production-grade surface and cylindrical grinding operations.\u003c\/p\u003e\u003cp\u003eThis wheel is intended for use on surface grinders and cylindrical grinders in industrial and toolroom environments. Its ceramic abrasive and semi-friable grain structure make it well suited for hard carbon steels, tool steels, 400 series stainless steel, titanium, super alloys, cast iron, ductile iron, and gray iron. The blue vitrified wheel is a common choice for precision grinding applications where heat generation and wheel breakdown must be carefully controlled.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 5 profile with one-side recess — 0.5 inches deep at 7.5 inches diameter\u003c\/li\u003e\n\u003cli\u003eCeramic abrasive grain for extended wheel life on hard and abrasive workpiece materials\u003c\/li\u003e\n\u003cli\u003eVitrified bond provides rigidity and porosity for free cutting action\u003c\/li\u003e\n\u003cli\u003e60 grit medium grade for efficient stock removal with moderate surface finish\u003c\/li\u003e\n\u003cli\u003eRated to 2070 RPM maximum operating speed\u003c\/li\u003e\n\u003cli\u003eCompatible with surface grinders and cylindrical grinders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with surface grinders and cylindrical grinders.

Always inspect the wheel for cracks or chips before mounting and perform a ring test. Power down and lockout the grinder before changing wheels. Never exceed the 2070 RPM maximum speed rating 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: 12 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\u003eHole Size\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Depth\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Diameter\u003c\/strong\u003e: 7.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: One-Side\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 5\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\u003eGrit\u003c\/strong\u003e: 60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: I\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriability\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 2070\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 10.92 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Series\u003c\/strong\u003e: 5SG60-IVSP\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: 66253263050\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538291851570,"sku":"66253263050","price":830.66,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c49a583f5e34396823ee46a5f4d4addc.jpg?v=1785822056","url":"https:\/\/voomisupply.com\/products\/norton-66253263050-surface-grinding-wheel-60-grit-12-in","provider":"Voomi Supply","version":"1.0","type":"link"}
