Built to NJ insert style specifications, it carries the KC5025 carbide grade with a PVD-applied TiAlN finish, delivering strong wear resistance and thermal stability at the cutting edge. Running at 8 threads per inch (TPI) with a 60-degree included angle, this insert is suited for UNJ thread standard applications where tight thread form tolerances are required. It is installed by machinists and CNC tooling technicians on Top Notch compatible toolholders. The corner radius measures 0.0193 decimal inches, and the insert thickness is 0.1949 decimal inches.\u003c\/p\u003e\u003cp\u003eThis insert is intended for external threading operations on lathes and turning centers using the Top Notch insert system. Its left-hand orientation makes it appropriate for specific thread direction requirements on turned components. The C2 and C6 material grade ratings indicate suitability for a range of workpiece materials encountered in general machining and aerospace-adjacent applications. Machinists working with UNJ thread forms will find this insert sized and coated for consistent, repeatable thread profiles across production runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC5025 carbide grade with PVD TiAlN coating for wear and heat resistance\u003c\/li\u003e\n\u003cli\u003eLeft-hand external thread orientation, 8 TPI pitch\u003c\/li\u003e\n\u003cli\u003e60-degree included angle for UNJ thread standard\u003c\/li\u003e\n\u003cli\u003eInsert size 3020, corner radius 0.0193 inches (0.49 mm)\u003c\/li\u003e\n\u003cli\u003eTop Notch series compatibility for secure indexing\u003c\/li\u003e\n\u003cli\u003eMaterial grade C2 and C6 rated\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series threading toolholders accepting NJ3020 style inserts for external left-hand UNJ threading applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or indexing the insert. Use the appropriate Top Notch torque key or clamping tool to secure the insert without overtightening the clamp screw.
