Measuring 12 inches in diameter and 1-1\/2 inches thick with a 5-inch arbor hole, this wheel uses a ceramic abrasive grain bonded in a vitrified matrix. The 46 grit, coarse grade designation suits applications where fast material removal takes priority over fine surface finish. At a maximum rated speed of 2,070 RPM, it is intended for use on industrial surface grinders and CNC cutting tool machines operated by skilled grinding technicians or tool-room personnel.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for surface grinding and cylindrical grinding operations in industrial and tool-room environments. It performs well on 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. The semi-friable ceramic grain continuously fractures to expose fresh cutting edges, which helps maintain cut rate and reduce heat buildup during extended grinding passes. It is a practical choice for shops that regularly process hard, abrasion-resistant materials where conventional aluminum oxide wheels wear too quickly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic abrasive grain with semi-friable characteristics for consistent cut rate on hard alloys\u003c\/li\u003e\n  \u003cli\u003eVitrified bond provides rigidity and porosity for coolant penetration and chip clearance\u003c\/li\u003e\n  \u003cli\u003e46 grit coarse grade removes material quickly on ferrous and super-alloy workpieces\u003c\/li\u003e\n  \u003cli\u003eType 1 flat wheel profile with no recess, compatible with standard surface and cylindrical grinder spindles\u003c\/li\u003e\n  \u003cli\u003eRated to 2,070 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eWheel color is blue; series designation 5SG Type 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always perform a ring test before mounting and verify the machine spindle speed does not exceed the wheel's 2,070 RPM maximum rating. Ensure the arbor hole fits the machine spindle with the correct flanges and blotters before tightening. True and dress the wheel after mounting before bringing a workpiece into contact.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Ceramic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\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: 1-1\/2 inches\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: 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: I\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness 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\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\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 5SG Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecifications\u003c\/strong\u003e: 5SG46-IVS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 12 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\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: 66253202842\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539000459570,"sku":"66253202842","price":816.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9de024470104425e3ecdf2a899988dee.jpg?v=1785832385","url":"https:\/\/voomisupply.com\/products\/norton-66253202842-surface-grinding-wheel-12in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
