Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent stock removal and a fine finish at a maximum operating speed of 3600 RPM. It measures 8 inches in diameter with a 1\/4 inch face width and a 1-1\/4 inch arbor hole. The vitrified bond structure is porous, promoting cool cutting and reduced glazing during extended runs. At 1.04 pounds, it is well suited for bench-mounted and CNC surface grinder setups where dimensional control matters. Grinding professionals and machinists are the primary installers and operators.\u003c\/p\u003e\u003cp\u003eThis wheel is rated for use on 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is intended for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. The fine grade and 100 grit rating make it appropriate for finishing passes and light stock removal rather than aggressive rough grinding. The 32A Type 1 series designation identifies it as a straight wheel with no recess and no taper, making it compatible with standard surface grinder spindle setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive with vitrified bond for consistent, cool cutting action\u003c\/li\u003e\n\u003cli\u003e100 grit fine grade for finish grinding and controlled stock removal\u003c\/li\u003e\n\u003cli\u003ePorous wheel structure reduces heat buildup and glazing during use\u003c\/li\u003e\n\u003cli\u003eRated to 3600 RPM maximum operating speed\u003c\/li\u003e\n\u003cli\u003eType 1 straight profile with no recess and no taper for standard spindle mounting\u003c\/li\u003e\n\u003cli\u003eCompatible with a broad range of ferrous and non-ferrous materials including stainless, tool steel, aluminum, and cast iron\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 power down and de-energize the machine before mounting or changing wheels. Inspect the wheel for cracks or chips using the ring test before installation, and never exceed the maximum rated RPM of 3600. Use appropriate flanges and blotters as specified by the machine manufacturer and applicable safety standards.\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\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: I\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\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 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Gray\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\u003eSeries\u003c\/strong\u003e: 32A Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecifications\u003c\/strong\u003e: 32A100-IVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.04 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: 66253043426\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540466762034,"sku":"66253043426","price":86.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9bf07293b6ae248a24b15269f5805ff2.jpg?v=1785856114","url":"https:\/\/voomisupply.com\/products\/norton-66253043426-surface-grinding-wheel-100-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
