Measuring 6 inches in diameter and 1\/16 inches thick with a 1-1\/4 inches arbor hole, this wheel uses synthetic diamond (SD) abrasive bonded in a resinoid matrix. At 220 grit with a Very Fine grade and a soft hardness rating (R), it is suited for controlled stock removal and surface finishing passes where tight tolerances and smooth finishes are required. The resinoid bond supports both wet and dry operation, giving technicians flexibility at the machine.\u003c\/p\u003e\u003cp\u003eThis wheel is designed for surface grinding applications that demand a very fine finish. It is well-suited for toolroom and production grinding of carbide, ceramics, glass, and other hard materials where conventional abrasive wheels are ineffective. The 1\/4 inches superabrasive depth provides adequate working material for finishing cycles. Machinists, toolroom operators, and precision grinding technicians working on surface grinders will find this wheel appropriate for final-stage material finishing rather than aggressive stock removal.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 1A1 straight wheel profile — flat face geometry for surface grinding applications\u003c\/li\u003e\n\u003cli\u003eSynthetic diamond (SD) abrasive at 100 concentration for consistent cutting action\u003c\/li\u003e\n\u003cli\u003e220 grit Very Fine grade produces smooth surface finishes on hard materials\u003c\/li\u003e\n\u003cli\u003eResinoid bond supports both wet and dry grinding operation\u003c\/li\u003e\n\u003cli\u003eSoft hardness rating (R) helps maintain sharp cutting edges on dense workpiece materials\u003c\/li\u003e\n\u003cli\u003eNo recess, no taper — straightforward mounting on standard surface grinder spindles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit surface grinding wheel for surface grinders accepting a 6 inches diameter, 1-1\/4 inches arbor hole, Type 1A1 straight wheel.

Always power down and lock out the surface grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before mounting, use the correct flanges and blotters as specified by the machine manufacturer, and never exceed the maximum operating speed marked on the wheel or its packaging.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Type\u003c\/strong\u003e: Type 1A1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Synthetic Diamond (SD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperabrasive Concentration\u003c\/strong\u003e: 100\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\u003eWheel Diameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 1\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Size\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuperabrasive Depth\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation Type\u003c\/strong\u003e: Wet and Dry\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: 0.7 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: 66260273599\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540354957618,"sku":"66260273599","price":551.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f641e77e4c48025b03243d4d56a0d2c3.jpg?v=1785853147","url":"https:\/\/voomisupply.com\/products\/norton-66260273599-surface-grinding-wheel-220-grit-diamond","provider":"Voomi Supply","version":"1.0","type":"link"}
