It features a synthetic diamond (SD) abrasive bonded in a resinoid matrix at 100 percent concentration, delivering consistent stock removal and fine surface finish. The wheel measures 6 inches in diameter, 0.125 inches thick, with a 1.25-inch arbor hole and a 0.25-inch superabrasive depth. Rated Very Fine at 220 grit with a soft hardness rating (R), this wheel is intended for wet operation. Licensed machinists, tool grinders, and precision grinding technicians install and dress this type of wheel.\u003c\/p\u003e\n\u003cp\u003eThis wheel is suited for wet surface grinding applications where a very fine finish is required, particularly in finishing passes on carbide, ceramic, glass, and other hard materials. The Type 1A1 straight wheel form fits standard surface grinder spindles. Its resinoid bond offers a degree of compliance that helps produce smooth surface finishes, making it appropriate for production finishing and precision toolroom work on flat workpiece surfaces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e220 grit synthetic diamond abrasive for very fine material finishing\u003c\/li\u003e\n  \u003cli\u003eResinoid bond at 100 percent superabrasive concentration for consistent cut and finish\u003c\/li\u003e\n  \u003cli\u003eType 1A1 straight wheel profile fits standard surface grinder spindles\u003c\/li\u003e\n  \u003cli\u003e0.25-inch superabrasive depth provides extended wheel life during finishing operations\u003c\/li\u003e\n  \u003cli\u003eSoft hardness rating (R) reduces heat buildup and glazing on hard workpiece materials\u003c\/li\u003e\n  \u003cli\u003eWet operation design supports coolant use for heat management and swarf control\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a Type 1A1 straight-form diamond surface grinding wheel for use on surface grinders with a 1.25-inch arbor, suitable for finishing carbide, ceramic, glass, and similarly hard or brittle materials.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified grinding machine operator or machinist with the grinder fully powered down and locked out before mounting. Inspect the wheel for cracks or chips before installation and conduct a ring test per ANSI B7.1 guidelines. Always use the correct flanges and blotters for the wheel diameter and never exceed the maximum operating speed marked on the wheel. Run the wheel at operating speed with the guard in place for at least one minute before bringing it into contact with the workpiece, and ensure coolant flow is established before beginning wet grinding.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Synthetic Diamond (SD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1A1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resinoid\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 220\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Very Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: R (Soft)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSuperabrasive Concentration\u003c\/strong\u003e: 100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Diameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.125 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\u003eSuperabrasive Depth\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWet\/Dry Operation\u003c\/strong\u003e: Wet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecess Type\u003c\/strong\u003e: No Recess\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTapered\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Norton Diamond\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: SD220-R100B99-1\/4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 66260273615\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540372291890,"sku":"66260273615","price":474.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/280097bf12944e1be2a8c1a704a305c0.jpg?v=1785853641","url":"https:\/\/voomisupply.com\/products\/norton-66260273615-surface-grinding-wheel-220-grit-6in","provider":"Voomi Supply","version":"1.0","type":"link"}
