Constructed with aluminum oxide abrasive and a vitrified bond, this wheel measures 12 inches in diameter, 1.5 inches thick, with a 5-inch arbor hole. The 46-grit, coarse-grade specification makes it well suited for aggressive material removal passes where surface finish is secondary to throughput. Rated at a maximum of 2,070 RPM, the wheel carries the 32A46-HVBE specification and is marked with an H hardness code in the soft-to-medium range. It weighs 9.75 pounds. Licensed grinding technicians and machining professionals install and dress this wheel on compatible grinding equipment.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for use on cylindrical grinders and surface grinders in production and maintenance machining environments. The aluminum oxide grain and vitrified bond combination performs reliably across a broad range of workpiece materials. Suitable for grinding 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The one-side recess design, with a 7.5-inch recess diameter and 0.5-inch recess depth, reduces wheel weight and allows clearance in recessed-hub flange setups common in surface grinding applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent cut rate and wheel integrity\u003c\/li\u003e\n  \u003cli\u003e46 grit coarse grade for aggressive stock removal on a wide range of metals\u003c\/li\u003e\n  \u003cli\u003eType 5 one-side recessed profile with 7.5-inch recess diameter and 0.5-inch recess depth\u003c\/li\u003e\n  \u003cli\u003eH hardness code in the soft range, reducing glazing on harder workpiece materials\u003c\/li\u003e\n  \u003cli\u003eMaximum operating speed of 2,070 RPM\u003c\/li\u003e\n  \u003cli\u003ePorous structure promotes chip clearance and coolant flow during wet or dry grinding\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with cylindrical grinders and surface grinders.

Always power down and lock out the grinder before mounting or dismounting any wheel. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the marked maximum RPM. Flanges and blotters must be clean, flat, and properly sized for the 5-inch arbor hole before tightening.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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: 1.5 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: 7.5 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\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: H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Soft\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\u003eWheel Type\u003c\/strong\u003e: Type 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: One-Side\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 2,070\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: Light Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: 32A46-HVBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9.75 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: 66253263164\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542176137522,"sku":"66253263164","price":554.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/499a7c8967ff9bac73e11045e8a34c54.jpg?v=1785894218","url":"https:\/\/voomisupply.com\/products\/norton-66253263164-surface-grinding-wheel-12in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
