Constructed with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent, controlled cutting action across a wide range of materials. The 46-grit coarse grade removes material aggressively while the J hardness code indicates a medium-hard bond that resists breakdown under sustained load. Rated at a maximum of 2070 RPM, it measures 12 inches in diameter, 1 inch thick, and carries a 3-inch arbor hole. Weight is 9.045 pounds. Licensed machinists and grinding technicians install this wheel on surface and cylindrical grinder spindles for flat surface finishing and tool reconditioning.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding operations in industrial machine shops, tool rooms, and production environments. Compatible materials include 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is designed for use with CNC cutting tool machines, cylindrical grinders, and surface grinders. The porous, non-tapered, no-recess design supports free cutting and heat dissipation during extended grinding passes.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent, repeatable cut rate\u003c\/li\u003e\n\u003cli\u003e46-grit coarse grade rated for aggressive material removal on a broad range of metals\u003c\/li\u003e\n\u003cli\u003eJ hardness (medium) bond resists glazing while holding form under load\u003c\/li\u003e\n\u003cli\u003eNon-tapered, no-recess Type 1 profile fits standard straight-wheel surface grinder flanges\u003c\/li\u003e\n\u003cli\u003ePorous wheel structure aids coolant penetration and chip clearance\u003c\/li\u003e\n\u003cli\u003eSpecification designation 32A46-JVBE identifies exact wheel composition for cross-referencing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with CNC cutting tool machines, cylindrical grinders, and surface grinders.

Before mounting, inspect the wheel for cracks or chips using a ring test and confirm the machine spindle speed does not exceed the 2070 RPM maximum rating marked on the wheel. Power down and lock out the grinder before removing the existing wheel and seating the new one. Use proper reducing bushings if required to achieve a snug, non-forced fit on the arbor, and always install blotter washers between the wheel and flanges as required by ANSI B7.1 safety standards.\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\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: J\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Designation\u003c\/strong\u003e: 32A46-JVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 46\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 2070\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 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 3 inches\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\u003eWheel Color\u003c\/strong\u003e: Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9.045 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\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: 66253262567\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540844052786,"sku":"66253262567","price":385.73,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7e1dfd3573ff5fc9f982265b92813bed.jpg?v=1785864805","url":"https:\/\/voomisupply.com\/products\/norton-66253262567-surface-grinding-wheel-12in-46-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
