Built from aluminum oxide abrasive bonded with a vitrified bond, this wheel delivers consistent, controlled cuts on hard carbon steels, soft carbon steels, and tool steels. It measures 8 inches in diameter, 0.75 inches thick, and features a 1.25-inch arbor hole. Rated at a maximum of 3105 RPM and specified at 46 grit with H hardness (coarse grade), it is suited for aggressive surface grinding operations performed by machinists and grinding technicians.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for use on surface grinders, cylindrical grinders, and CNC cutting tool machines in machine shops and tool rooms handling ferrous workpieces. The coarse 46-grit rating makes it appropriate for high-material-removal passes on hard and soft carbon steels as well as tool steels. The porous structure promotes coolant flow and chip clearance during extended grinding cycles, reducing heat buildup at the workpiece surface.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive for reliable performance on ferrous metals including hard carbon steels, soft carbon steels, and tool steels\u003c\/li\u003e\n  \u003cli\u003eVitrified bond construction provides rigidity and consistent wheel shape throughout the wheel life\u003c\/li\u003e\n  \u003cli\u003eCoarse 46-grit rating supports high material removal rates\u003c\/li\u003e\n  \u003cli\u003ePorous wheel structure aids coolant penetration and chip evacuation\u003c\/li\u003e\n  \u003cli\u003eMaximum rated speed of 3105 RPM for safe operation on compatible machines\u003c\/li\u003e\n  \u003cli\u003eType 1 straight profile with no recess, compatible with standard surface and cylindrical grinder arbors\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.

Always power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before each use using the ring test, and never operate above the maximum rated RPM stamped on the wheel or listed on its blotter. Use appropriate flanges and a compressible blotter on each side of the wheel when mounting.\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: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eArbor Hole 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\u003eHardness 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\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\u003eMaximum RPM\u003c\/strong\u003e: 3105\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: 32AA46-HVTRP\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 32A Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Hard Carbon Steels, Soft Carbon Steels, Tool Steels\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: 66253007166\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538259607858,"sku":"66253007166","price":179.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6bfb1362887e8231489c0766aa2ec361.jpg?v=1785821115","url":"https:\/\/voomisupply.com\/products\/norton-66253007166-surface-grinding-wheel-46-grit-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
