It measures 4 inches in diameter and 1\/16 inch thick, with a 1-1\/4 inch hole size, and uses a resinoid bond with synthetic diamond (SD) abrasive at 150 grit. The Very Fine grade designation makes it well suited for applications where surface finish quality matters alongside material removal. A superabrasive depth of 1\/4 inch and 100 concentration rating indicate a high-density abrasive section for consistent, repeatable performance. Tool and die makers, surface grind operators, and machine shop technicians are the primary users of this wheel.\u003c\/p\u003e\u003cp\u003eThis wheel is built for surface grinding operations on hard and brittle materials, including carbide tooling, ceramics, glass, and hardened steels where conventional abrasives underperform. It supports both wet and dry operation, giving the operator flexibility based on workpiece material and available coolant systems. The roughing and finishing material application rating means this single wheel can handle stock removal and surface refinement within the same setup, reducing changeover time in production or tool-room environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 1A1 straight wheel geometry for standard surface grinding spindle setups\u003c\/li\u003e\n\u003cli\u003eSynthetic diamond abrasive at 150 grit Very Fine grade for controlled material removal and smooth finish\u003c\/li\u003e\n\u003cli\u003eResinoid bond with Hardness Code R (Soft) for free cutting action on hard workpiece materials\u003c\/li\u003e\n\u003cli\u003e100 superabrasive concentration for high, consistent abrasive density across the wheel face\u003c\/li\u003e\n\u003cli\u003eCompatible with both wet and dry grinding operations\u003c\/li\u003e\n\u003cli\u003eNo recess, no taper — straightforward mounting on standard surface grinder arbors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct specification match for Type 1A1 diamond surface grinding wheel applications on standard surface grinders accepting a 1-1\/4 inch hole arbor and 4 inch diameter wheel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eSurface grinding wheels must be installed by qualified machine operators or tool room technicians familiar with grinding wheel safety standards. Always power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or chips before mounting and perform a ring test per ANSI B7.1 guidelines. Do not exceed the maximum operating speed marked on the wheel, and always dress the wheel before initial use to ensure proper seating and concentricity.\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: 1\/16 inch\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\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\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\u003eBond Type\u003c\/strong\u003e: Resinoid\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\u003eSuperabrasive Depth\u003c\/strong\u003e: 1\/4 inch\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 and Finishing\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: SD150-R100B99-1\/4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Norton Diamond\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: 66260273584\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51542507684146,"sku":"66260273584","price":374.96,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b8ee9b1ca7abd7475cff1c5bc1a7d50d.jpg?v=1785902352","url":"https:\/\/voomisupply.com\/products\/norton-66260273584-surface-grinding-wheel-150-grit-diamond","provider":"Voomi Supply","version":"1.0","type":"link"}
