Built to the 16 ER insert style, it features a physical vapor deposition (PVD) TiAlN coating that improves heat resistance and extends tool life during high-speed threading operations. The insert carries a 3\/8 inch inscribed circle and measures 0.146 inches thick. It is used in CNC lathes and turning centers by machinists and toolroom professionals working to UNJ aerospace and precision thread standards. The HG225TR grade designation indicates its engineered substrate and coating combination for threading applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for precision threading in aerospace, defense, and industrial manufacturing environments where UNJ thread profiles are specified. UNJ threads feature a controlled root radius that reduces stress concentrations, making them common in high-fatigue and safety-critical applications. The 16ER13UNJHG225T is a right-hand insert, meaning it cuts with standard right-hand toolholder orientation on a conventional lathe setup. It is sold individually per package with a minimum order quantity of 10 units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in threading operations\u003c\/li\u003e\n\u003cli\u003eTiAlN PVD coating for elevated heat resistance and extended cutting life\u003c\/li\u003e\n\u003cli\u003eExternal UNJ thread profile with 13 TPI for aerospace-standard thread cutting\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation for standard lathe and CNC turning setups\u003c\/li\u003e\n\u003cli\u003e16 ER insert style for compatibility with standard ER-style threading toolholders\u003c\/li\u003e\n\u003cli\u003e3\/8 inch inscribed circle and 0.146 inch thickness for precise seating and repeatability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in 16 ER-style external threading toolholders configured for right-hand UNJ thread cutting applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThreading inserts are installed and serviced by machinists and CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and insert screw specified by the toolholder manufacturer to secure the insert without cracking the carbide substrate.
