At 7 inches in diameter and 1\/2 inch thick with a 1-1\/4 inch arbor hole, it mounts to standard surface grinders and cylindrical grinders. The 80-grit, medium-grade abrasive delivers a balance of cut rate and finish quality, and the H hardness code indicates a soft-to-medium bond that releases dull grains readily to expose fresh cutting edges. Maximum operating speed is 3,600 RPM. The Series 32A designation identifies the bond system and grain structure used in this wheel.\u003c\/p\u003e\n\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. It is suited to surface grinders and cylindrical grinders in tool rooms, machine shops, and maintenance environments. CNC cutting tool machines are also listed as compatible equipment. The non-porous, non-tapered, non-recessed profile makes this a straightforward flat-wheel application on standard spindle setups requiring a 1-1\/4 inch bore.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive — effective on steels, cast iron, and aluminum\u003c\/li\u003e\n  \u003cli\u003e80 grit, medium grade — balanced cut rate and surface finish\u003c\/li\u003e\n  \u003cli\u003eH hardness code with vitrified bond — promotes self-dressing action during use\u003c\/li\u003e\n  \u003cli\u003eType 1 flat wheel geometry — no recess, no taper, straightforward mounting\u003c\/li\u003e\n  \u003cli\u003e3,600 RPM maximum rated speed\u003c\/li\u003e\n  \u003cli\u003eSeries 32A bond specification: 80H8V32A\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines.

Before mounting, inspect the wheel for cracks using the ring test and confirm the machine spindle speed does not exceed the 3,600 RPM maximum rating stamped on the wheel. Power down and lock out the grinder before changing wheels. Always use the correct flanges and blotters for the arbor bore size and never force the wheel onto the spindle.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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: 0.5 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\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1\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\u003eMaximum RPM\u003c\/strong\u003e: 3,600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 80H8V32A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 32A Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePorous\u003c\/strong\u003e: Non-Porous\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: Blue, Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.86 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 66253246829\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51544071373106,"sku":"66253246829","price":31.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/277bccba93430a9216a6e536a2c5a2b6.jpg?v=1785923656","url":"https:\/\/voomisupply.com\/products\/norton-66253246829-surface-grinding-wheel-80-grit-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
