Built around an aluminum oxide abrasive with a vitrified bond, this wheel delivers consistent cut rate and form retention throughout its service life. It measures 8 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole. The 60-grit, J-hardness (medium grade) specification makes it well suited for moderate material removal where surface finish and wheel life must both be considered. Rated at a maximum of 3,600 RPM, it is sized for benchtop and floor-standing surface grinders used in tool rooms and production grinding applications. Licensed machinists and grinding technicians are the primary installers and operators of this wheel.\u003c\/p\u003e\u003cp\u003eThis wheel is rated for use on hard carbon steels, soft carbon steels, and tool steels. Its vitrified bond structure provides an open, porous matrix that resists loading and maintains free-cutting action during extended passes. The 32AA60-JVTR specification designates the full abrasive formulation for shops that need to cross-reference or match existing wheel specs. The wheel ships individually and is designed for use on surface grinders, cylindrical grinders, and CNC cutting tool machines.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive — effective on hard and soft carbon steels and tool steels\u003c\/li\u003e\n\u003cli\u003eVitrified bond with porous structure resists loading and supports free-cutting action\u003c\/li\u003e\n\u003cli\u003e60 grit, J hardness (medium grade) balances material removal rate with wheel longevity\u003c\/li\u003e\n\u003cli\u003eType 1 straight wheel profile with no recess — straightforward mounting on standard arbors\u003c\/li\u003e\n\u003cli\u003e3,600 RPM maximum operating speed\u003c\/li\u003e\n\u003cli\u003eFull specification code: 32AA60-JVTR\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines requiring a Type 1 straight wheel with a 1-1\/4 inch arbor hole and 8 inch diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGrinding wheel mounting and dressing must be performed by a qualified machinist or grinding technician. Before mounting, inspect the wheel for cracks or chips using the ring test per ANSI B11.9 and OSHA 29 CFR 1910.215 guidelines. Power down and lock out the grinder before changing wheels, and confirm the machine spindle speed does not exceed the 3,600 RPM rating stamped on the wheel. Always use the correct flanges and blotters, and allow the wheel to run at operating speed for at least one minute behind a guard before grinding.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1 (Straight, No Recess)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Vitrified\u003c\/li\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\u003eArbor Hole Size\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 60\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: J\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStructure\u003c\/strong\u003e: Porous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3,600\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Specification\u003c\/strong\u003e: 32AA60-JVTR\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\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: 66253038895\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539560431922,"sku":"66253038895","price":141.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c11b4f5e904397f08d3397d5ca27020f.jpg?v=1785843050","url":"https:\/\/voomisupply.com\/products\/norton-66253038895-surface-grinding-wheel-8in-60-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
