Built with a resinoid bond and a medium hardness rating (code T), this wheel delivers consistent stock removal during roughing and cut-off operations. At 120 grit with a fine grade, it produces controlled surface finishes while maintaining cut rate. The superabrasive CBN layer is 1\/4 inch deep with a 75 concentration rating, providing a long-lasting abrasive section suited for high-production grinding environments. Machinists and tool-and-die professionals working with hardened steels and superalloys rely on CBN wheels like this one for extended wheel life over conventional abrasives.\u003c\/p\u003e\u003cp\u003eThis wheel is suited for surface grinding applications in machine shops, tool rooms, and manufacturing operations where conventional aluminum oxide or silicon carbide wheels fall short. The Type 1A1 straight-wheel profile fits standard surface grinder spindle setups. At 6 inches in diameter with a 1-1\/4 inch arbor hole and 1\/2 inch thickness, it mounts directly to compatible surface grinder spindles without adapter modifications in most configurations. The resinoid bond provides good shock resistance, making it appropriate for interrupted-cut surface grinding as well as continuous-pass operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCBN (cubic boron nitride) superabrasive for grinding hardened steels and superalloys\u003c\/li\u003e\n\u003cli\u003eType 1A1 straight wheel profile for standard surface grinder compatibility\u003c\/li\u003e\n\u003cli\u003e120 grit, fine grade for controlled stock removal with smooth surface results\u003c\/li\u003e\n\u003cli\u003eResinoid bond with medium hardness (T) for balanced cut rate and wheel life\u003c\/li\u003e\n\u003cli\u003e1\/4 inch superabrasive depth and 75 concentration for extended productive life\u003c\/li\u003e\n\u003cli\u003eNo recess, no taper — straightforward mounting on compatible arbors\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit CBN grinding wheel for surface grinders accepting a 6 inch diameter, 1-1\/4 inch arbor hole, Type 1A1 straight wheel.

Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or chips before installation and perform a ring test per ANSI B7.1 standards. Never exceed the maximum operating speed marked on the wheel.\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\u003eWheel Diameter\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Thickness\u003c\/strong\u003e: 0.5 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\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\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\u003eSeries\u003c\/strong\u003e: Norton CBN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecification\u003c\/strong\u003e: CB120-TB99-1\/4\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\u003eWeight\u003c\/strong\u003e: 1.4 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: 66260273607\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORTON","offers":[{"title":"Default Title","offer_id":51539106791730,"sku":"66260273607","price":1303.52,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6d3912c6d150b6906f44d97d2c89e82c.jpg?v=1785834783","url":"https:\/\/voomisupply.com\/products\/norton-66260273607-cbn-surface-grinding-wheel-120-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
