Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cutting action and thermal stability under repeated use. It measures 7 inches in diameter, 1\/4 inch thick, and carries a 1-1\/4 inch arbor hole. The fine grade, 120 grit specification suits finish grinding passes where surface quality matters. Rated to 3600 RPM, it is sized for bench-top and floor-model surface grinders used in production and toolroom environments.\u003c\/p\u003e\u003cp\u003eThis wheel is rated for use on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Compatible machine types include surface grinders, cylindrical grinders, and CNC cutting tool machines. The porous, gray-bodied wheel carries a hardness code of L, placing it in the medium hardness range, which balances wheel life against free-cutting behavior on a broad range of workpiece materials. It is a practical choice for toolroom technicians and production grinding operators who need reliable consistency across varied material applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for controlled, consistent material removal\u003c\/li\u003e\n\u003cli\u003e120 grit, fine grade for finish grinding and close-tolerance surface work\u003c\/li\u003e\n\u003cli\u003eHardness code L (medium) balances wheel life with cutting efficiency\u003c\/li\u003e\n\u003cli\u003ePorous structure aids coolant flow and reduces heat buildup at the grinding interface\u003c\/li\u003e\n\u003cli\u003e3600 RPM maximum operating speed\u003c\/li\u003e\n\u003cli\u003eType 1 flat wheel profile, no recess, no taper — direct drop-in for standard arbor setups\u003c\/li\u003e\n\u003cli\u003eSeries designation 32A120-LVBE for specification-driven procurement\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.

Always inspect the wheel for cracks or chips before mounting — do not use a damaged wheel. Power down and lockout the grinder before changing wheels. Verify the machine spindle speed does not exceed the 3600 RPM maximum marked on the wheel, and use the correct flange and blotter assembly for the 1-1\/4 inch arbor bore.\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: 32A120-LVBE\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: 0.25 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\u003eGrit\u003c\/strong\u003e: 120\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: L\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\u003ePorous\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Gray\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\u003eWeight\u003c\/strong\u003e: 0.8 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: 66252911685\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51544529830194,"sku":"66252911685","price":79.91,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a8103fc80d8e0ce74567edc0e4323624.jpg?v=1785928900","url":"https:\/\/voomisupply.com\/products\/norton-66252911685-surface-grinding-wheel-120-grit-7in","provider":"Voomi Supply","version":"1.0","type":"link"}
