Built with a ceramic abrasive grain and a vitrified bond, this wheel delivers consistent stock removal and long wheel life in high-production grinding operations. The coarse 46 grit and G hardness code (soft hardness rating) allow the wheel to cut freely and release dull grains quickly, maintaining an open, aggressive cutting action. Rated at a maximum of 2320 RPM, it is sized at 14 inches in diameter and 1-1\/2 inches thick with a 5-inch arbor hole. A licensed HVAC tech or surface grinder operator in a tool-and-die or maintenance shop environment would typically install and dress this wheel for precision flat grinding applications.\u003c\/p\u003e\n\u003cp\u003eThis grinding wheel is suited for use on surface grinders and cylindrical grinders in both industrial and maintenance shop environments. It is designed for grinding 400 series stainless steel, hard carbon steels, tool steels, titanium, super alloys, cast iron, ductile iron, and gray iron. The semi-friable ceramic grain structure makes it particularly effective on hard, heat-sensitive materials where conventional aluminum oxide wheels would glaze or burn the workpiece. The one-side recessed Type 5 profile with an 8-inch recess diameter and 1\/2-inch recess depth suits flange-mount configurations common on production surface grinders.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCeramic abrasive grain with vitrified bond for consistent cut rate and extended wheel life\u003c\/li\u003e\n  \u003cli\u003e46 grit coarse grade with G (soft) hardness rating for free-cutting, self-dressing action\u003c\/li\u003e\n  \u003cli\u003eType 5 one-side recessed profile: 8-inch recess diameter, 1\/2-inch recess depth\u003c\/li\u003e\n  \u003cli\u003eMaximum operating speed of 2320 RPM — verify this rating before mounting\u003c\/li\u003e\n  \u003cli\u003eSemi-friable grain construction reduces heat buildup on sensitive alloys and stainless steel\u003c\/li\u003e\n  \u003cli\u003eCompatible with surface grinders and cylindrical grinders across a broad range of ferrous workpiece materials\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 power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips using a ring test before installation, and never exceed the maximum RPM stamped on the wheel or listed on the blotter. Use proper flanges and a clean, undamaged arbor to ensure secure, centered mounting.\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\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 5\u003c\/li\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: 1.5 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 Diameter\u003c\/strong\u003e: 8 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\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: G\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: Soft\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 2320\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFriability\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Purple\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3SG Type 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 3SGR46-GVP2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 13.5 pounds\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: 66253319953\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540524630322,"sku":"66253319953","price":687.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/15c410973f7cda61546a256c4a01c1bb.jpg?v=1785857480","url":"https:\/\/voomisupply.com\/products\/norton-66253319953-type-5-surface-grinding-wheel-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
