Manufactured to the IR series in style 11IR with an IC908 grade coated carbide substrate, this insert delivers consistent thread form on right-hand internal applications. The 60-degree included angle matches the UN thread profile precisely, while the Z chipbreaker geometry helps manage chip flow during threading passes. With a 1\/4-inch inscribed circle and a corner radius of 0.0071 inches, this insert suits production and maintenance threading operations performed by machinists and tool and die professionals.\u003c\/p\u003e\n\u003cp\u003eThe ISCAR 3409672 is suited for internal threading operations on CNC lathes and manual turning centers where UN-standard thread profiles are required. Its right-hand orientation and 10 TPI specification make it a direct fit for threading bores on components in manufacturing, repair, and job shop environments. The IC908 coated grade is appropriate for a broad range of ferrous workpiece materials at moderate cutting parameters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIR series 11IR insert style with 60-degree included angle for UN thread profile accuracy\u003c\/li\u003e\n  \u003cli\u003eIC908 coated solid carbide grade for wear resistance across ferrous materials\u003c\/li\u003e\n  \u003cli\u003eZ chipbreaker geometry for controlled chip evacuation during internal threading\u003c\/li\u003e\n  \u003cli\u003e10 threads per inch UN internal thread standard, right-hand cut\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch (0.2500-inch) inscribed circle with 0.0071-inch corner radius\u003c\/li\u003e\n  \u003cli\u003eLaydown seating style for rigid, repeatable insert positioning in compatible toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement threading insert for IR-series internal threading toolholders accepting 11IR-style laydown inserts with UN thread form geometry.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists following standard insert indexing procedures. Power down and lock out the machine before seating or replacing the insert.
