It measures 14 inches in diameter, 1 inch thick, with a 5-inch arbor hole. The wheel is constructed from ceramic abrasive grain bonded with a vitrified bond, producing a semi-friable, porous structure that resists loading and maintains a sharp cutting face longer than conventional aluminum oxide wheels. Rated at a maximum of 1800 RPM, it carries an I hardness code and medium grade classification. Licensed HVAC, machine, and tool-room technicians rely on this wheel for precision surface and cylindrical grinding applications.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for production and maintenance grinding on 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. Compatible machine types include surface grinders, cylindrical grinders, and CNC cutting tool machines. Its porous, semi-friable ceramic grain structure makes it especially effective on heat-sensitive materials where minimizing workpiece burn is critical. The blue wheel color identifies the 5SG ceramic series, specification 5SG60-IVSP.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCeramic abrasive grain with vitrified bond for consistent, cool-cutting action\u003c\/li\u003e\n\u003cli\u003eSemi-friable, porous structure resists loading on hard and exotic alloys\u003c\/li\u003e\n\u003cli\u003eI hardness code, medium grade — balances wheel life and free cutting on dense materials\u003c\/li\u003e\n\u003cli\u003e14-inch diameter, 1-inch face width for broad contact on surface grinder tables\u003c\/li\u003e\n\u003cli\u003e5-inch arbor hole fits standard production surface and cylindrical grinder spindles\u003c\/li\u003e\n\u003cli\u003e1800 RPM maximum speed rating, Type 1 flat wheel configuration, no recess\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.

Before mounting, inspect the wheel for cracks using a ring test and confirm the spindle speed does not exceed the 1800 RPM maximum rating stamped on the wheel. Power down and lock out the machine before changing wheels, and always use the correct flanges and blotters for the arbor size. A fresh wheel should be dressed before first use to true the face and expose fresh abrasive grain.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: I\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 (No Recess, Not Tapered)\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\u003eStructure\u003c\/strong\u003e: Porous, Semi-Friable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 1800\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: 5SG60-IVSP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5SG Type 1\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: 3.31 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: 66253363871\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542499033394,"sku":"66253363871","price":918.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f8f87964c3cd0f0947321ad3b05712d8.jpg?v=1785902080","url":"https:\/\/voomisupply.com\/products\/norton-66253363871-surface-grinding-wheel-60-grit-14-in","provider":"Voomi Supply","version":"1.0","type":"link"}
