Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent, controlled cutting action across surface and cylindrical grinding applications. At 46 grit with a K hardness rating and semi-friable grain structure, the wheel self-dresses efficiently and maintains a sharp cutting face throughout its service life. The porous structure promotes coolant flow and reduces heat buildup at the workpiece. Rated to 3600 RPM, it is sized at 7 inches in diameter, 1 inch thick, and carries a 1-1\/4 inch arbor hole for secure mounting on compatible spindles.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for use on surface grinders and cylindrical grinders in production and maintenance shop environments, handling both ferrous and high-performance alloy workpieces. The coarse 46-grit specification makes it appropriate for aggressive material removal passes rather than finish grinding. Its Type 5 geometry features a 3-inch recess diameter and 1\/2-inch recess depth on one side, which accommodates specific spindle nose configurations common on surface grinding setups. Typical users include machinist-trade professionals and tool room operators working on ferrous metals and demanding super alloy components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for durable, open cutting action\u003c\/li\u003e\n\u003cli\u003e46 grit, coarse grade for efficient material removal on soft carbon steels, tool steels, and super alloys\u003c\/li\u003e\n\u003cli\u003eK hardness (medium) with semi-friable grain structure promotes consistent self-dressing\u003c\/li\u003e\n\u003cli\u003ePorous wheel structure aids coolant penetration and reduces thermal loading\u003c\/li\u003e\n\u003cli\u003eType 5 recessed geometry with 3-inch recess diameter and 1\/2-inch recess depth on one side\u003c\/li\u003e\n\u003cli\u003eRated to 3600 RPM maximum operating speed\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 conduct a ring test per wheel manufacturer guidelines. Power down and lock out the grinder before changing wheels. Never exceed the maximum operating speed of 3600 RPM 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: 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: 3 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: Aluminum Oxide\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: K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFriable\u003c\/strong\u003e: Semi-Friable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 38A Type 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecifications\u003c\/strong\u003e: 38A46-KVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Soft Carbon Steels, Tool Steels, Super Alloys\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.93 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: 66252942793\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539335512370,"sku":"66252942793","price":107.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9691794fdd901c4e5c46b62c1963ad2.jpg?v=1785838499","url":"https:\/\/voomisupply.com\/products\/norton-66252942793-surface-grinding-wheel-46-grit-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
