Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rate and form retention across high-cycle production and toolroom applications. It measures 12 inches in diameter, 1 inch thick, with a 5 inch arbor hole, and carries a 60 grit, K hardness (medium grade) specification. The vitrified bond structure is porous, promoting free cutting action and efficient chip clearance. Maximum rated speed is 2705 RPM. Installation is performed by qualified grinding machine operators or maintenance machinists following ANSI B7.1 safety standards.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding operations on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. Compatible equipment includes surface grinders, cylindrical grinders, and CNC cutting tool machines. The 12 inch diameter and 5 inch hole sizing position this wheel for mid-to-large capacity production surface grinders common in job shops and manufacturing environments. The 32A60-KVBE specification identifies it within the Norton 32A Type 1 series, a well-established line for precision ferrous grinding.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive for effective grinding of steels, cast irons, and aluminum\u003c\/li\u003e\n\u003cli\u003eVitrified bond with porous structure for free-cutting action and reduced heat buildup\u003c\/li\u003e\n\u003cli\u003e60 grit, K hardness (medium grade) delivers a balance of material removal rate and surface finish\u003c\/li\u003e\n\u003cli\u003eType 1 straight wheel profile, no recess, no taper — fits standard surface and cylindrical grinder spindles\u003c\/li\u003e\n\u003cli\u003eRated to 2705 RPM maximum operating speed\u003c\/li\u003e\n\u003cli\u003eNorton 32A series specification: 32A60-KVBE\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 perform a ring test before mounting and inspect the wheel for cracks or chips. Power down and lock out the grinder before changing wheels, and verify the machine RPM rating meets or exceeds the wheel maximum of 2705 RPM before operation. Never exceed the rated maximum speed marked on the wheel.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 5 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: K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Medium\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\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\u003eWheel Color\u003c\/strong\u003e: Gray\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 2705\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: 32A60-KVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 32A Type 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 7.973 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: 66253262691\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539930022194,"sku":"66253262691","price":379.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/39a316e36ca99d3108246f3d48fb0166.jpg?v=1785845084","url":"https:\/\/voomisupply.com\/products\/norton-66253262691-surface-grinding-wheel-60-grit-12-in","provider":"Voomi Supply","version":"1.0","type":"link"}
