Built with a synthetic diamond (SD) abrasive and a resinoid bond, this wheel delivers consistent material removal at a fine 120 grit rating. It measures 7 inches in diameter, 0.25 inches thick, with a 1.25-inch arbor hole, and weighs 1.5 pounds. The wheel carries a soft hardness rating (Code R) and a superabrasive concentration of 100, making it well suited for controlled roughing and cut-off work on hard, abrasive materials. Installation and operation are performed by skilled grinding machine operators in shop and production environments.\u003c\/p\u003e\u003cp\u003eThis wheel is intended for surface grinding operations where a fine finish and consistent stock removal are required. It is rated for both wet and dry operation, giving operators flexibility depending on coolant availability and workpiece requirements. The 0.25-inch superabrasive depth provides adequate grinding life for roughing and cut-off tasks. With no recess and no taper, it mounts flat and concentric on compatible surface grinding spindles. The Norton Diamond series is commonly found in tool rooms, production shops, and maintenance facilities working with hard materials such as ceramics, carbide, and hardened steel.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSynthetic diamond (SD) abrasive for effective grinding of hard, abrasive materials\u003c\/li\u003e\n\u003cli\u003eResinoid bond provides controlled cut action and smooth finish at 120 grit fine grade\u003c\/li\u003e\n\u003cli\u003eRated for both wet and dry operation for application flexibility\u003c\/li\u003e\n\u003cli\u003eType 1A1 straight wheel geometry with no recess and no taper for flat, concentric mounting\u003c\/li\u003e\n\u003cli\u003eSuperabrasive concentration of 100 for consistent, uniform material removal\u003c\/li\u003e\n\u003cli\u003eSoft wheel hardness (Code R) reduces glazing on demanding workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use grinding wheel for surface grinding machines accepting a 7-inch diameter, 1.25-inch arbor hole, Type 1A1 straight wheel configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified grinding machine operator following the machine manufacturer's mounting instructions and all applicable ANSI B7.1 safety standards for abrasive wheels. Always power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before installation and perform a ring test where applicable. Do not exceed the maximum operating speed marked on the wheel or the machine, whichever is lower.\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: 0.25 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\u003eGrit\u003c\/strong\u003e: 120\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Rating\u003c\/strong\u003e: Soft\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness Code\u003c\/strong\u003e: R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Synthetic Diamond (SD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resinoid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1A1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperabrasive Concentration\u003c\/strong\u003e: 100\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: Roughing\/Cut-Off\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\u003eSpecification Code\u003c\/strong\u003e: SD120-R100B99-1\/4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Norton Diamond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.5 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: 66260273566\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51544089035058,"sku":"66260273566","price":778.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4563a2fc56434ac333418b1f31d685bc.jpg?v=1785923932","url":"https:\/\/voomisupply.com\/products\/norton-66260273566-surface-grinding-wheel-120-grit-7in","provider":"Voomi Supply","version":"1.0","type":"link"}
