Built with a resinoid bond and medium hardness (hardness code T), it delivers controlled stock removal at 120 grit, a fine grade suited for finishing passes and tight-tolerance surface work. The wheel measures 7 inches in diameter, 0.25 inches thick, with a 1.25-inch arbor hole and a superabrasive depth of 0.25 inches. Wet operation is specified, making it appropriate for high-production surface grinding setups where coolant is available. Machinists, tool-and-die makers, and grinding specialists are the primary installers.\u003c\/p\u003e\u003cp\u003eThis wheel is intended for roughing and cut-off operations on ferrous materials, particularly hardened tool steels, high-speed steels, and superalloys where conventional abrasives wear too quickly. The Type 1A1 flat-wheel profile fits standard surface grinding machines with a 1.25-inch spindle bore. Its 75 concentration CBN formulation balances wheel life with consistent cut rates across extended production runs. No recess and no taper keep setup straightforward on compatible surface grinders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCBN abrasive material for long wheel life on hardened ferrous workpieces\u003c\/li\u003e\n\u003cli\u003e120 grit, fine grade for controlled stock removal and surface finish\u003c\/li\u003e\n\u003cli\u003eResinoid bond with medium hardness (T) for stable, consistent grinding action\u003c\/li\u003e\n\u003cli\u003eWet operation design requires coolant for optimal performance and wheel longevity\u003c\/li\u003e\n\u003cli\u003eType 1A1 flat profile with no recess and no taper for straightforward machine mounting\u003c\/li\u003e\n\u003cli\u003e75 CBN concentration balances cut rate with extended service life\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on surface grinding machines equipped with a 1.25-inch arbor bore accepting a Type 1A1 straight wheel.

Power down and lock out the grinder before mounting or removing the wheel. Use proper flanges and blotters as specified by the machine manufacturer, and never exceed the wheel's rated maximum operating speed. Ring-test the wheel before mounting to check for cracks or damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Cubic Boron Nitride (CBN)\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: 120\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: T (Medium)\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: 0.25 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: 75\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\/Cut-Off\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\u003eSeries\u003c\/strong\u003e: Norton CBN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification Code\u003c\/strong\u003e: CB120-TB99-1\/4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.35 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: 69014192021\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51541252505906,"sku":"69014192021","price":972.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/639aa4f179722d59ae67dccd7f0aa803.jpg?v=1785870780","url":"https:\/\/voomisupply.com\/products\/norton-69014192021-cbn-surface-grinding-wheel-120-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
