Built with a synthetic diamond (SD) abrasive and a resinoid bond, this wheel delivers consistent stock removal and a fine surface finish in wet grinding applications. At 7 inches in diameter, 3\/8 inches thick, and with a 1-1\/4 inch arbor hole, it mounts on standard surface grinding equipment. The 220 grit, very fine grade makes it well suited for final-pass finishing rather than aggressive material removal. Wheel hardness is rated Soft (R), and the superabrasive depth is 1\/4 inch at 100 percent concentration.\u003c\/p\u003e\u003cp\u003eThis wheel is intended for finishing operations on carbide, ceramics, glass, hardened tool steels, and other hard substrates where conventional abrasives lose efficiency. The Type 1A1 straight-wheel profile fits standard surface grinder spindles. Wet operation is required to maintain wheel integrity, manage heat, and flush swarf. Toolroom machinists, grinding specialists, and precision fabrication shops are the primary installers and operators of this wheel.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSynthetic diamond (SD) abrasive for grinding hard and brittle materials\u003c\/li\u003e\n\u003cli\u003eResinoid bond provides controlled wear and smooth cutting action\u003c\/li\u003e\n\u003cli\u003e220 grit very fine grade optimized for finishing passes\u003c\/li\u003e\n\u003cli\u003eType 1A1 straight wheel profile with no recess for broad spindle compatibility\u003c\/li\u003e\n\u003cli\u003eWet operation design for heat management and extended wheel life\u003c\/li\u003e\n\u003cli\u003e100 percent superabrasive concentration (SD220-R100B99-1\/4) for consistent performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-fitment superabrasive grinding wheel for surface grinders accepting a 7 inch diameter, 1-1\/4 inch arbor hole, Type 1A1 straight wheel configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and dressing of superabrasive wheels should be performed by a qualified grinding machine operator or toolroom technician familiar with ANSI B7.1 wheel safety standards. Power down and lock out the grinder before mounting or removing the wheel. Inspect the wheel for cracks or damage before each use and verify that the machine's maximum RPM rating meets or exceeds the wheel's rated speed. Wet coolant flow must be active before the wheel contacts the workpiece to prevent thermal damage to the bond and abrasive layer.\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\u003eWheel Diameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.375 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\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\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\u003eMaterial Application\u003c\/strong\u003e: Finishing\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\u003eSeries\u003c\/strong\u003e: Norton Diamond\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.83 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: 69014191852\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51540259995954,"sku":"69014191852","price":919.06,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4cc3fc7e12252bead0bd9961a367bf55.jpg?v=1785850534","url":"https:\/\/voomisupply.com\/products\/norton-69014191852-surface-grinding-wheel-7in-220-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
