It measures 8 inches in diameter and 1\/4 inch thick with a 1-1\/4 inch arbor hole. The wheel is constructed from aluminum oxide abrasive bonded in a vitrified bond matrix, rated at 100 grit with a Fine grade and K hardness code. Rated for a maximum of 3600 RPM, it is suited for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. Licensed machinists, tool and die makers, and grinding specialists are the primary installers and operators of this wheel.\u003c\/p\u003e\u003cp\u003eThis wheel is appropriate for both light and medium-duty surface grinding applications in job shop, maintenance, and production environments. Its aluminum oxide abrasive and vitrified bond make it well suited for grinding 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The Fine grade designation indicates it is intended for finishing passes and closer-tolerance work rather than aggressive bulk removal.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive for broad metal compatibility including stainless, carbon steels, and cast iron\u003c\/li\u003e\n\u003cli\u003eVitrified bond for rigidity, porosity, and consistent cut rate\u003c\/li\u003e\n\u003cli\u003e100 grit Fine grade delivers smooth surface finishes\u003c\/li\u003e\n\u003cli\u003eK hardness code provides medium wheel hardness for balanced wear and cut retention\u003c\/li\u003e\n\u003cli\u003ePorous structure aids coolant flow and chip clearance during grinding\u003c\/li\u003e\n\u003cli\u003eType 1 straight wheel profile with no recess for standard surface and cylindrical grinder mounting\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 perform a ring test before mounting and inspect the wheel for cracks or chips. Power down and de-energize the grinder completely before changing wheels, and confirm the machine spindle speed does not exceed the 3600 RPM maximum stamped on the wheel. A proper flange set and blotter must be used during installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 8 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\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\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 100\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: K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Hardness 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\u003eSpecification Series\u003c\/strong\u003e: 32A100-KVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.05 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: 66253043428\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542373761330,"sku":"66253043428","price":84.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4d2f9cee2044e4bc9b73458c3ddcb28c.jpg?v=1785898895","url":"https:\/\/voomisupply.com\/products\/norton-66253043428-surface-grinding-wheel-8in-100-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
