Built with a vitrified bond and rated at a coarse 46 grit with J hardness, this wheel delivers consistent cut rates and controlled breakdown on demanding workpieces. It measures 7 inches in diameter and 1 inch thick, with a 1-1\/4 inch arbor hole and a one-side recess measuring 2-3\/4 inches in diameter and 0.5 inches deep. Maximum operating speed is 3,600 RPM. The ceramic abrasive grain is semi-friable, continuously exposing fresh cutting edges during use. Licensed machinists, tool and die shops, and industrial grinding technicians are the primary installers and operators.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for precision surface grinding and cylindrical grinding applications across a range of hard and difficult-to-grind materials. Rated applications include 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. The recessed Type 5 profile accommodates clearance needs on surface grinders and cylindrical grinders where a flat Type 1 wheel would interfere with workholding fixtures. It is appropriate for both production and maintenance grinding environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic abrasive grain — semi-friable construction continuously exposes sharp cutting edges for consistent material removal rates\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigidity and porosity for coolant flow and chip clearance\u003c\/li\u003e\n  \u003cli\u003e46 grit coarse grade suited for rapid stock removal rather than finish grinding\u003c\/li\u003e\n  \u003cli\u003eJ hardness rating — medium wheel hardness balances grain retention with controlled breakdown\u003c\/li\u003e\n  \u003cli\u003eType 5 one-side recessed profile with 2-3\/4 inch recess diameter and 0.5 inch recess depth for fixture clearance\u003c\/li\u003e\n  \u003cli\u003eRated for 400 series stainless, tool steels, titanium, super alloys, and iron grades\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with surface grinders and cylindrical grinders.

Always inspect the wheel for cracks or damage before mounting and perform a ring test. Never exceed the rated maximum speed of 3,600 RPM. Power down and lock out the grinder before changing wheels, and use the correct flanges and blotters for the arbor size.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 7 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: 1-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Diameter\u003c\/strong\u003e: 2-3\/4 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 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: 46\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: J\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\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\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3,600 RPM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 5SG46-JVS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5SG Type 5\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: 66252942427\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539998540082,"sku":"66252942427","price":248.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3fa167602e44b45fdc181c2bbb0fd748.jpg?v=1785845340","url":"https:\/\/voomisupply.com\/products\/norton-66252942427-surface-grinding-wheel-46-grit-7in-type-5","provider":"Voomi Supply","version":"1.0","type":"link"}
