Running the NT3RK insert style in the KC720 grade with a PVD-applied Titanium Nitride (TiN) finish, this insert delivers reliable wear resistance and edge integrity across a range of threading applications. It covers a 60-degree partial profile thread form and accommodates both internal and external threading in a right-hand configuration. The Top Notch series design ensures secure, repeatable seating in compatible toolholders. Machinists and CNC operators working with ISO and inch-standard threads will find this insert suited to production and job-shop environments alike.\u003c\/p\u003e\u003cp\u003eThis insert handles external pitch ranges of 1.25 to 4.00 mm and 6 to 20 TPI, and internal pitch ranges of 2.00 to 5.00 mm and 5 to 12 TPI. It is appropriate for threading operations on steels and harder alloys where material grades C3 and C4 carbide apply. The K-style chipbreaker geometry helps manage chip flow during threading cuts, reducing the risk of chip packing in tight bores or fine-pitch thread forms. Typical applications include production threading on turned components in general metalworking, aerospace, and industrial fabrication environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC720 carbide grade with PVD Titanium Nitride (TiN) finish for wear and heat resistance\u003c\/li\u003e\n\u003cli\u003eNT3RK insert style in the Top Notch series for secure, repeatable toolholder engagement\u003c\/li\u003e\n\u003cli\u003e60-degree partial profile thread form covers both internal and external applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting geometry with K-style chipbreaker for controlled chip evacuation\u003c\/li\u003e\n\u003cli\u003eExternal pitch: 1.25 to 4.00 mm and 6 to 20 TPI; Internal pitch: 2.00 to 5.00 mm and 5 to 12 TPI\u003c\/li\u003e\n\u003cli\u003eMaterial grades C3 and C4 suitability for a broad range of workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Top Notch series threading toolholders that accept NT3 insert style.
