Built with a synthetic diamond (SD) abrasive and resinoid bond, this wheel delivers consistent material removal and finishing performance at a very fine 150 grit grade. The wheel measures 6 inches in diameter and 1\/8 inches thick, with a 1-1\/4 inches arbor hole. It is rated for wet operation and carries a soft hardness rating (R-grade), making it well-suited for controlled stock removal and fine finishing passes. Licensed machinists, tool grinders, and industrial maintenance technicians are the primary installers and operators of this wheel.\u003c\/p\u003e\n\u003cp\u003eThis grinding wheel is intended for roughing and finishing operations on hard and brittle materials where diamond abrasive provides a clear performance advantage over conventional abrasives. The Type 1A1 straight-wheel geometry fits standard surface grinder spindles accepting a 1-1\/4 inches arbor. With a 1\/4 inches superabrasive depth and 100 concentration of synthetic diamond abrasive, the wheel is built for production-level consistency. It is part of the Norton Diamond series and suits applications in precision grinding shops, toolrooms, and industrial maintenance settings handling carbide, ceramic, glass, and similar hard materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSynthetic diamond (SD) abrasive at 100 concentration for consistent cutting performance\u003c\/li\u003e\n  \u003cli\u003e150 grit very fine grade for controlled stock removal and smooth surface finish\u003c\/li\u003e\n  \u003cli\u003eResinoid bond provides good shock resistance and self-dressing characteristics\u003c\/li\u003e\n  \u003cli\u003eSoft hardness rating (R-code) reduces heat buildup and promotes free cutting action\u003c\/li\u003e\n  \u003cli\u003eRated for wet operation, compatible with standard water-soluble and oil-based grinding coolants\u003c\/li\u003e\n  \u003cli\u003eType 1A1 straight-wheel form with no recess and no taper for straightforward spindle mounting\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\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 inches arbor hole and a 6 inches diameter wheel capacity.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or grinding equipment operator following the grinder manufacturer's spindle speed and mounting specifications. 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 standards. Never exceed the maximum RPM rating marked on the wheel, and always use appropriate coolant flow when operating in wet mode.\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: 150\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: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.125 inches (1\/8 inches)\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 inches)\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 and Finishing\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\u003eSpecification Code\u003c\/strong\u003e: SD150-R100B99-1\/4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: 66260273613\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539066814770,"sku":"66260273613","price":559.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dff3d795e3c8d366d32015960bfea13f.jpg?v=1785834213","url":"https:\/\/voomisupply.com\/products\/norton-66260273613-surface-grinding-wheel-150-grit-6in","provider":"Voomi Supply","version":"1.0","type":"link"}
