Running the KC5025 grade with a PVD-applied TiAlN coating, this insert handles right-hand internal threading at 14 threads per inch. The insert follows ISO code LT16NR14NPT and features a 3\/8-inch (9.53 mm) inscribed circle and a thickness of 0.1430 inches (3.44 mm). The TiAlN finish provides heat and wear resistance suited to interrupted cuts and continuous threading passes on hard or abrasive materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for production and job-shop threading operations on steel, stainless steel, cast iron, superalloys, and titanium. It fits standard NR-style toolholders accepting size 16 inserts and is suited to applications where consistent NPT thread form and finish are required. The right-hand cutting geometry and internal thread configuration make it a direct fit for pipe-thread programs on CNC turning centers targeting 3\/8-inch NPT bore profiles.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with KC5025 manufacturer grade for toughness and edge retention\u003c\/li\u003e\n  \u003cli\u003ePVD TiAlN coating for thermal resistance and extended tool life on ferrous and superalloy workpieces\u003c\/li\u003e\n  \u003cli\u003e14 TPI NPT internal thread form, right-hand cut\u003c\/li\u003e\n  \u003cli\u003eInsert size code 16 with 3\/8-inch inscribed circle and 0.1430-inch thickness\u003c\/li\u003e\n  \u003cli\u003eHole diameter of 0.1551 inches for standard screw-lock toolholder mounting\u003c\/li\u003e\n  \u003cli\u003eCompatible workpiece materials include steel, stainless steel, cast iron, superalloys, and titanium\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for NR-style insert seats accepting size 16 laydown threading inserts.
