Built on a resinoid bond with synthetic diamond (SD) abrasive at 100 concentration, this wheel delivers consistent cut rate and controlled surface finish during wet roughing operations. The wheel measures 4 inches in diameter, 1\/16 inch thick, with a 1-1\/4 inch arbor hole. At 100 grit and a fine grade with soft hardness (R), it suits applications where dimensional accuracy and surface integrity are critical. Grinding technicians and tool room machinists are the typical installers.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for wet surface grinding operations in tool and die, carbide tooling, ceramics, and hard material roughing applications. The 1\/4 inch superabrasive depth provides adequate wheel life for production and maintenance grinding tasks. The Type 1A1 straight wheel profile fits standard surface grinder spindles equipped with a 1-1\/4 inch arbor. It is part of the Norton Diamond series and is intended for roughing passes where stock removal is the primary objective.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSynthetic diamond (SD) abrasive at 100 concentration for aggressive, consistent cutting action on hard materials\u003c\/li\u003e\n\u003cli\u003eResinoid bond provides shock resistance and smooth grinding action during wet operation\u003c\/li\u003e\n\u003cli\u003e100 grit fine grade with soft hardness code R for controlled material removal without excessive wheel loading\u003c\/li\u003e\n\u003cli\u003eType 1A1 straight wheel profile with no recess for direct spindle mounting on standard surface grinders\u003c\/li\u003e\n\u003cli\u003e1\/4 inch superabrasive depth extends usable wheel life through repeated dressing cycles\u003c\/li\u003e\n\u003cli\u003eWet operation design helps manage heat, extend abrasive life, and maintain workpiece dimensional tolerances\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit grinding wheel for surface grinders equipped with a 1-1\/4 inch arbor spindle accepting Type 1A1 straight wheels up to 4 inches in diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eA licensed machinist or qualified grinding technician should mount and dress this wheel. Before mounting, inspect the wheel for cracks or chips and perform a ring test per ANSI B7.1 standards. Power down and lock out the grinder before changing wheels. Never exceed the wheel speed rating marked on the wheel or packaging, and always use the appropriate flanges and blotter pads when mounting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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 inch)\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\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: 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: 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\u003eWet\/Dry Operation\u003c\/strong\u003e: Wet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Roughing\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: SD100S-R100B99-1\/4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 66260273583\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51538399723826,"sku":"66260273583","price":374.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/117fe86d5eb1f4f9ca65f4f82b4b69a4.jpg?v=1785824548","url":"https:\/\/voomisupply.com\/products\/norton-66260273583-diamond-surface-grinding-wheel-4in-100g","provider":"Voomi Supply","version":"1.0","type":"link"}
