Built with aluminum oxide abrasive and a vitrified bond, it delivers consistent cut rates and thermal stability across extended grinding cycles. The wheel measures 7 inches in diameter and 3\/4 inches thick with a 1-1\/4 inch arbor hole, and is rated to a maximum of 3600 RPM. At 46 grit with an I hardness code (coarse grade, medium hardness rating), it is suited for aggressive material removal rather than fine finishing work. Machinists, tool-and-die workers, and grinding machine operators are the primary users.\u003c\/p\u003e\u003cp\u003eThis wheel is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. Its coarse, porous structure makes it well-matched to hard carbon steels, soft carbon Steels, and tool steels where rapid stock removal is the priority. The one-side recessed profile (recess diameter 3 inches, recess depth 1\/4 inch) allows proper fitment on compatible machine spindles. The gray aluminum oxide abrasive self-dresses during use, maintaining a free-cutting action throughout the wheel life. This wheel follows the 32A Type 1 series specification, designated 32AA46-IVTR.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for thermal stability and consistent cut rate\u003c\/li\u003e\n\u003cli\u003e46 grit, coarse grade for aggressive stock removal on ferrous metals\u003c\/li\u003e\n\u003cli\u003eI hardness code, medium hardness rating balances wheel life with cut aggressiveness\u003c\/li\u003e\n\u003cli\u003ePorous wheel structure promotes coolant flow and chip clearance during grinding\u003c\/li\u003e\n\u003cli\u003eOne-side recess (3 inches diameter, 1\/4 inch depth) for proper spindle fitment\u003c\/li\u003e\n\u003cli\u003eMaximum spindle speed rated at 3600 RPM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Always inspect the wheel for cracks or chips using the ring test before mounting, and never exceed the rated maximum RPM of 3600. Power down and lockout the machine before mounting or removing the wheel. Use properly matched flanges and a blotter gasket on each side of the wheel as required by the machine manufacturer.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\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\u003eSeries\u003c\/strong\u003e: 32A Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 32AA46-IVTR\u003c\/li\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: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1.25 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: 0.25 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: I\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: Medium\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: Gray\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\u003eWeight\u003c\/strong\u003e: 0.195 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: 66252938885\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541297922354,"sku":"66252938885","price":159.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9e3d3fc3368556c3d52addd2b0a51fb3.jpg?v=1785871641","url":"https:\/\/voomisupply.com\/products\/norton-66252938885-surface-grinding-wheel-46-grit-7in","provider":"Voomi Supply","version":"1.0","type":"link"}
