Built with aluminum oxide abrasive and a vitrified bond, this wheel measures 7 inches in diameter, 3\/4 inches thick, with a 1-1\/4 inches arbor hole. It runs at a maximum of 3,600 RPM and carries a 60 grit, K hardness (medium grade) rating — a combination well suited to controlled material removal on hard and soft steels, cast iron, and aluminum. The vitrified bond provides consistent grain exposure and good wheel breakdown behavior under surface grinding loads. Licensed machinists, tool room technicians, and industrial maintenance trades are the primary installers and operators.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding and cylindrical grinding applications in tool room, production, and maintenance environments. It performs across a broad range of materials including 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 porous, gray-colored wheel body supports coolant flow and chip clearance during wet or dry grinding operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAluminum oxide abrasive for versatile use on steels, cast irons, and aluminum\u003c\/li\u003e\n\u003cli\u003eVitrified bond delivers consistent grain exposure and stable wheel geometry\u003c\/li\u003e\n\u003cli\u003e60 grit, K hardness medium grade balances cut rate and surface finish\u003c\/li\u003e\n\u003cli\u003ePorous wheel structure supports coolant flow and chip evacuation\u003c\/li\u003e\n\u003cli\u003eType 1 straight profile fits standard surface grinder and cylindrical grinder spindles\u003c\/li\u003e\n\u003cli\u003eRated to 3,600 RPM maximum operating speed\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 inspect the wheel for cracks or chips before mounting and perform a ring test per standard procedure. Power down and lock out the grinder before changing wheels, and verify that spindle RPM does not exceed the 3,600 RPM maximum rating marked on the wheel. Use the correct flange size and paper blotter washers to ensure even clamping pressure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 0.75 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: 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\u003eMaximum RPM\u003c\/strong\u003e: 3,600\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\u003eSpecification Code\u003c\/strong\u003e: 32A60-KVBE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.38 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\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: 66252941943\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542035824946,"sku":"66252941943","price":122.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/82449c5a3825c059696ebeb4e3a2ed59.jpg?v=1785890278","url":"https:\/\/voomisupply.com\/products\/norton-66252941943-surface-grinding-wheel-60-grit-7-in","provider":"Voomi Supply","version":"1.0","type":"link"}
