It measures 6 inches in diameter, 0.5 inches thick, with a 1.25 inch arbor hole. The abrasive grain is aluminum oxide bonded in a vitrified bond matrix, rated K hardness (medium) at a coarse 46 grit. The specification code 32AA46-KVTR identifies the exact wheel formulation for shops that cross-reference grinding wheel specs. Maximum operating speed is 4140 RPM. Licensed grinding technicians and toolroom machinists are the primary installers of this wheel type.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface and cylindrical grinding applications on hard carbon steels, soft carbon steels, and tool steels. The vitrified bond provides a rigid, porous structure that allows coolant penetration and efficient swarf clearance, making it appropriate for both wet and dry surface grinding setups. The 6 inch diameter and coarse 46 grit combination is commonly used for aggressive material removal passes before finishing operations. It fits standard surface grinder spindle configurations accepting a 1.25 inch arbor hole.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive grain for effective cutting action on ferrous materials including tool steels\u003c\/li\u003e\n\u003cli\u003eVitrified bond construction provides a rigid, porous wheel structure for good coolant flow and swarf removal\u003c\/li\u003e\n\u003cli\u003e46 grit coarse grade suited for high stock removal grinding passes\u003c\/li\u003e\n\u003cli\u003eK hardness code (medium) balances wheel wear against cutting efficiency on a range of steel hardness levels\u003c\/li\u003e\n\u003cli\u003eType 1 straight wheel profile with no recess, compatible with standard surface grinder and cylindrical grinder spindles\u003c\/li\u003e\n\u003cli\u003eMaximum operating speed rated at 4140 RPM\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines accepting a Type 1 straight wheel with a 1.25 inch arbor hole and 6 inch diameter.

Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the maximum RPM stamped on the wheel or stated in the product specification. Ensure the machine spindle speed does not exceed 4140 RPM for this wheel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\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\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.5 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\u003eMaximum RPM\u003c\/strong\u003e: 4140\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 32AA46-KVTR\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\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: 66252835093\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542902047026,"sku":"66252835093","price":102.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/60729405395100990c0d3044b8584b35.jpg?v=1785910375","url":"https:\/\/voomisupply.com\/products\/norton-66252835093-surface-grinding-wheel-46-grit-6-in","provider":"Voomi Supply","version":"1.0","type":"link"}
