The insert is made from 85% cubic boron nitride (CBN), grade CBN200, and carries a bright uncoated finish. It features a negative rake geometry with a honed cutting edge style, six usable cutting edges on a double-sided configuration, and a 0-degree relief angle. These characteristics make it well suited for high-hardness interrupted and continuous milling applications where thermal and wear resistance are critical performance factors. The insert is held in the cutter body via a wedge clamp and is compatible with the R220.68-16 cutter series.\u003c\/p\u003e\u003cp\u003eThis insert is intended for machining cast iron and hard materials, designated material application codes K and H respectively. It is used in face milling and shoulder milling operations on CNC machining centers in both production and job-shop environments. The neutral hand orientation allows flexible positioning in compatible toolholders. Metalworking shops running high-volume cast iron components or hardened steel parts will find this insert appropriate for finishing and semi-finishing passes where tight dimensional tolerances and surface finish are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e85% CBN composition, grade CBN200, for high wear resistance in hard and abrasive workpiece materials\u003c\/li\u003e\n\u003cli\u003eTriangular insert shape (60-degree included angle) with six cutting edges for extended tool life per insert\u003c\/li\u003e\n\u003cli\u003eDouble-sided design maximizes usable cutting edges before replacement\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge style reduces microchipping during interrupted cuts in cast iron\u003c\/li\u003e\n\u003cli\u003eNegative rake geometry provides strong edge support at higher feed rates\u003c\/li\u003e\n\u003cli\u003eUncoated bright finish maintains dimensional accuracy of the CBN substrate without coating buildup\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with the SECO R220.68-16 cutter series. Insert designation TNGN1604PNS conforms to ISO and ANSI standards, making it dimensionally interchangeable with other TNGN1604PNS-compliant toolholders that accept wedge-clamp style triangular inserts.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or tooling technicians. The machine spindle must be fully stopped and locked out before seating or replacing inserts. Use a torque wrench calibrated to the toolholder manufacturer's specified value for the wedge clamp fastener — do not use impact tools on clamping screws. Inspect the insert pocket for chips or debris before seating; contamination in the pocket can cause insert rocking and premature edge failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TNGN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI \/ ISO Code\u003c\/strong\u003e: TNGN1604PNS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: PCBN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: CBN200\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 85% CBN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\u003c\/strong\u003e: Bright \/ Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Double\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Wedge Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: None\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 1604\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.3748 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1874 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches (1\/32 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Effective Length\u003c\/strong\u003e: 0.6495 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1949 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron (Code K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Hard Material (Code H)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: R220.68-16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291601\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 02573306\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563588911410,"sku":"02573306","price":470.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d3f0bf4e889f58ba861e942ae4d73caa.jpg?v=1786499509","url":"https:\/\/voomisupply.com\/products\/seco-02573306-cbn-milling-insert-tngn1604pns-triangle","provider":"Voomi Supply","version":"1.0","type":"link"}
