Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cutting action and open structure suited to fine-finish surface grinding applications. It measures 7 inches in diameter, 1\/4 inch thick, and carries a 1-1\/4 inch arbor hole. The 100-grit, K-hardness (medium) rating makes it appropriate for controlled material removal where surface finish quality matters. Rated to a maximum of 3,600 RPM, it is installed and operated by machinists and tool room technicians on compatible surface grinding equipment.\u003c\/p\u003e\n\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. Typical applications include toolroom surface grinders and CNC cutting tool machines as well as cylindrical grinders. The porous, vitrified-bonded construction promotes coolant flow and chip clearance during wet or dry grinding, making it a practical choice for both production and maintenance grinding tasks in industrial and shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAluminum oxide abrasive for consistent performance on steel, stainless, and iron workpieces\u003c\/li\u003e\n  \u003cli\u003eVitrified bond with porous structure aids coolant penetration and chip clearance\u003c\/li\u003e\n  \u003cli\u003e100 grit, fine grade delivers smooth surface finishes with controlled stock removal\u003c\/li\u003e\n  \u003cli\u003eK hardness (medium) rating balances wheel wear against cutting efficiency\u003c\/li\u003e\n  \u003cli\u003eType 1 flat wheel profile with no recess — straightforward mounting on standard arbors\u003c\/li\u003e\n  \u003cli\u003eMaximum operating speed of 3,600 RPM\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 requiring a Type 1 wheel with a 1-1\/4 inch arbor hole.

Always inspect the wheel for cracks or chips before mounting and perform a ring test. Ensure the machine spindle speed does not exceed the 3,600 RPM maximum rating marked on the wheel. Power down and lock out the grinder before changing wheels, and allow the wheel to run at operating speed for at least one minute behind a guard before bringing it into contact with the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 0.25 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: 100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Rating\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: 3,600\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 32A Type 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecifications\u003c\/strong\u003e: 32A100-KVBE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.8 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23131503\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: 66252939673\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540134461746,"sku":"66252939673","price":80.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f4ac15fb8cd8e2b5455c059aaf00fde0.jpg?v=1785846676","url":"https:\/\/voomisupply.com\/products\/norton-66252939673-surface-grinding-wheel-7in-100-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
