Featuring a Titanium Nitride (TiN) finish applied via PVD coating process, this insert carries the KC730 manufacturer grade and is rated for material grades C2, C3, and C4. It cuts right-hand external threads to the UNJ thread standard at 24 threads per inch (TPI) with a 60-degree included angle. The NJK insert style seats in Top Notch series toolholders. With a corner radius of 0.0068 inches and a tip-to-top height of 0.1409 inches, it is built for controlled thread form accuracy in production turning environments. Machinists and CNC operators in aerospace, defense, and precision manufacturing install this type of insert.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external threading operations on lathes and turning centers where UNJ thread profiles are required. The KC730 grade with PVD TiN coating provides wear resistance when threading steels and other materials in the C2 through C4 material grade range. It is commonly used in job shops and production facilities running Top Notch compatible tooling systems that demand consistent thread geometry and repeatable insert seating across high-volume runs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC730 carbide grade with PVD-applied Titanium Nitride (TiN) coating for extended tool life\u003c\/li\u003e\n\u003cli\u003eCuts external UNJ threads at 24 TPI with a 60-degree included angle\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation for standard lathe and turning center setups\u003c\/li\u003e\n\u003cli\u003eNJK insert style fits Top Notch series toolholders\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0068 inches for precise thread form geometry\u003c\/li\u003e\n\u003cli\u003eInsert size 3007 with a thickness of 0.1949 inches for consistent seating depth\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series toolholders accepting NJK-style inserts.
