Built with a synthetic diamond abrasive and a resinoid bond, this wheel delivers consistent material removal at a very fine 220 grit rating. It measures 4 inches in diameter, 1\/16 inch thick, with a 1-1\/4 inch hole size, and carries a soft hardness rating (Code R) with 100 percent superabrasive concentration. The 1\/4 inch superabrasive depth provides extended wheel life during finishing operations. Suitable for use in both wet and dry grinding conditions, this wheel is sized for bench and surface grinders used in tool rooms, machine shops, and precision grinding environments.\u003c\/p\u003e\n\u003cp\u003eThis wheel is intended for finishing operations on hard and brittle materials where tight tolerances and fine surface finishes are required. Its Type 1A1 straight wheel profile fits standard surface grinder spindles with a 1-1\/4 inch arbor. The very fine 220 grit makes it appropriate for final-pass material removal rather than aggressive stock reduction. Machinists, tool grinders, and precision fabricators working with carbide, ceramics, glass, or similarly hard substrates will find this wheel suited to their finishing stage workflow.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSynthetic diamond abrasive provides long-lasting cutting performance on hard, brittle materials\u003c\/li\u003e\n  \u003cli\u003e220 grit very fine grade suited for finishing and final-pass surface work\u003c\/li\u003e\n  \u003cli\u003eResinoid bond offers controlled cut rate with good surface finish results\u003c\/li\u003e\n  \u003cli\u003eType 1A1 straight wheel profile with no recess and no taper for broad spindle compatibility\u003c\/li\u003e\n  \u003cli\u003eRated for both wet and dry operation, supporting coolant use or dry grinding as needed\u003c\/li\u003e\n  \u003cli\u003eSoft wheel hardness (Code R) helps prevent glazing when grinding hard workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit grinding wheel for surface grinders and bench grinders accepting a 1-1\/4 inch arbor hole and Type 1A1 straight wheel geometry.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or tool room technician. Power down and lock out the grinder before mounting or removing any grinding wheel. Inspect the wheel for cracks or chips before installation and perform a ring test per ANSI B7.1 guidelines. Use proper flanges and never exceed the wheel's rated maximum operating speed.\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\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\u003eBond Type\u003c\/strong\u003e: Resinoid\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: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.0625 inches (1\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1.25 inches (1-1\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSuperabrasive Depth\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\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\u003eWet\/Dry Operation\u003c\/strong\u003e: Wet and Dry\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: 0.4 pounds\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: 66260273586\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540704067890,"sku":"66260273586","price":374.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d487a9091294de013e278c4e1fbd85fc.jpg?v=1785862427","url":"https:\/\/voomisupply.com\/products\/norton-66260273586-surface-grinding-wheel-220-grit-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
