Built to the NJK insert style in the Top Notch series, it carries a KC5025 carbide grade with a PVD-applied TiAlN finish for improved wear resistance and heat tolerance at elevated cutting speeds. The insert cuts right-hand external threads to the UNJ thread standard at 14 TPI with a 60-degree included angle. It measures 0.1409 inches tip to top and 0.1949 inches thick, with a corner radius of 0.0110 inches. Licensed machinists and CNC tooling specialists are the primary users of this insert.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external threading applications on aerospace-grade and precision-machined components where UNJ thread form compliance is required. The UNJ thread standard features a controlled root radius, making it common in aerospace and defense manufacturing. The KC5025 grade performs well across a range of ferrous and difficult-to-machine alloys. It fits Top Notch-compatible toolholders accepting the NJK insert style in the 3012 insert size. Minimum order quantity is 5 units; supplier packaging ships as individual units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC5025 carbide grade with PVD TiAlN coating for extended tool life in demanding materials\u003c\/li\u003e\n\u003cli\u003eNJK insert style, 3012 insert size, compatible with Top Notch series toolholders\u003c\/li\u003e\n\u003cli\u003eCuts UNJ external right-hand threads at 14 TPI with a 60-degree included angle\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0110 inches for controlled root form on UNJ-compliant threads\u003c\/li\u003e\n\u003cli\u003eTip to top height of 0.1409 inches; insert thickness of 0.1949 inches\u003c\/li\u003e\n\u003cli\u003eMaterial grades C2 and C6 coverage for broad application range\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Top Notch series toolholders that accept the NJK insert style in the 3012 insert size for external threading operations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThreading inserts of this type are installed and indexed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the correct torque wrench and clamp screw specified for the Top Notch toolholder to seat the insert properly  -  do not overtighten by hand.
