It measures 7 inches in diameter, 1\/2 inch thick, with a 1-1\/4 inch arbor hole. The wheel uses synthetic diamond (SD) abrasive bonded in a resinoid matrix at 100 percent concentration, producing a Very Fine, 220-grit cut. The superabrasive depth is 1\/4 inch. This wheel is rated for wet operation and carries a soft wheel hardness (R hardness code). It is installed and dressed by grinding machine operators and tool room technicians working on precision surface grinding equipment.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for finishing applications where tight surface finish tolerances are required. The 220 grit and Very Fine grade make it appropriate for final-pass grinding on ceramics, carbides, glass, ferrite, and similar hard or brittle workpiece materials. The resinoid bond provides good cutting action and a consistent finish in wet grinding conditions. It fits standard surface grinders with a 1-1\/4 inch spindle bore and is sold individually.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 1A1 straight wheel profile with no recess and no taper\u003c\/li\u003e\n\u003cli\u003eSynthetic diamond (SD) abrasive at 100 percent superabrasive concentration\u003c\/li\u003e\n\u003cli\u003e220 grit Very Fine grade for precision finishing passes\u003c\/li\u003e\n\u003cli\u003eResinoid bond system rated for wet operation\u003c\/li\u003e\n\u003cli\u003e1\/4 inch superabrasive depth for extended wheel life\u003c\/li\u003e\n\u003cli\u003eSoft hardness rating (R) for controlled stock removal on hard materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit wheel for surface grinders accepting a Type 1A1 straight wheel with a 1-1\/4 inch bore, 7 inch diameter, and 1\/2 inch face width.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDiamond grinding wheels must be mounted and dressed by qualified machine operators following the grinder manufacturer's instructions and ANSI B7.1 safety standards. Always ring-test the wheel before mounting and ensure the spindle speed does not exceed the wheel's rated maximum RPM. Power down and lock out the grinder before changing wheels. Wet grinding operation requires adequate coolant flow to the wheel face throughout the grinding cycle to prevent heat buildup and workpiece damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.5 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: 2.31 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: 69014191857\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51544626364722,"sku":"69014191857","price":1052.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e7bf6ae2613be3d8352496a07ea9079e.jpg?v=1785931937","url":"https:\/\/voomisupply.com\/products\/norton-69014191857-diamond-grinding-wheel-220-grit-7in","provider":"Voomi Supply","version":"1.0","type":"link"}
