It measures 8 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole. The wheel uses aluminum oxide abrasive bonded in a vitrified matrix, rated at a coarse 46 grit with an H hardness code. The blue-colored 32A series wheel carries a maximum operating speed of 3,105 RPM. Vitrified bond construction provides rigidity and consistent cut geometry, making it a reliable choice for surface grinder work in production and job-shop environments. Installation and operation should only be performed by qualified grinding machine operators familiar with abrasive wheel safety standards.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for flat surface grinding operations on hard carbon steels, soft carbon steels, and tool steels. The coarse 46 grit cuts aggressively for rapid material removal while the H hardness rating keeps the wheel from loading prematurely on softer grades of steel. It mounts on surface grinders, cylindrical grinders, and CNC cutting tool machines equipped with the appropriate 1-1\/4 inch arbor. The Type 1 straight-wheel profile fits standard horizontal and vertical spindle surface grinder setups commonly found in tool rooms and machining shops.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e46 grit coarse aluminum oxide abrasive for aggressive stock removal\u003c\/li\u003e\n  \u003cli\u003eVitrified bond for rigid, consistent cutting action and easy dressing\u003c\/li\u003e\n  \u003cli\u003eH hardness code with porous structure reduces heat buildup and wheel loading\u003c\/li\u003e\n  \u003cli\u003eType 1 straight-wheel profile with no recess and no taper for broad spindle compatibility\u003c\/li\u003e\n  \u003cli\u003eRated to 3,105 RPM maximum operating speed\u003c\/li\u003e\n  \u003cli\u003eSuitable for hard carbon steels, soft carbon steels, and tool steels\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with surface grinders, cylindrical grinders, and CNC cutting tool machines equipped with a 1-1\/4 inch arbor.

Always ring-test the wheel for cracks before mounting and never exceed the rated maximum RPM of 3,105. Ensure the machine spindle is fully de-energized and locked out before changing wheels. Use proper flanges and blotters as specified for the wheel diameter and arbor size; do not overtighten the arbor nut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 0.5 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: 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: H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Hardness Rating\u003c\/strong\u003e: Soft\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\u003eSeries\u003c\/strong\u003e: 32A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 32AA46-HVTRP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3,105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Blue\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\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: 66253007161\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541968191794,"sku":"66253007161","price":137.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fda9a0ba04dd09066279807d1a421b93.jpg?v=1785888596","url":"https:\/\/voomisupply.com\/products\/norton-66253007161-surface-grinding-wheel-46-grit-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
