Built to the Top Notch insert system standard, it carries the NTC3L10E geometry and KCU10 carbide grade with a PVD-applied AlTiN finish. The insert produces a 60-degree included angle thread profile at 10 threads per inch (TPI) and features a corner radius of 0.0124 inches (0.32 mm). The KCU10 grade is suited for threading operations where edge toughness and coating wear resistance are priorities. This insert is installed by machinists and CNC operators working in production or job-shop turning environments.\u003c\/p\u003e\u003cp\u003eThis insert is used for external left-hand UN thread cutting in turning center and lathe applications. The Top Notch series toolholder system is a common platform in production threading setups. The AlTiN PVD coating provides thermal resistance during dry or semi-dry threading passes. At 10 TPI, it covers standard UN thread pitches used across general mechanical fastener and component manufacturing. It is appropriate for both production runs and prototype threading work where a left-hand thread form is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKCU10 carbide grade with PVD AlTiN finish for wear and thermal resistance\u003c\/li\u003e\n\u003cli\u003eLeft-hand external thread orientation for left-hand UN thread cutting\u003c\/li\u003e\n\u003cli\u003e10 TPI pitch with a 60-degree included angle per UN thread standard\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0124 inches (0.32 mm) for accurate thread root form\u003c\/li\u003e\n\u003cli\u003eTop Notch (NTC) insert series for compatibility with Top Notch toolholders\u003c\/li\u003e\n\u003cli\u003eInsert Size 3 with a thickness of 0.195 inches (4.95 mm)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series threading toolholders that accept NTC Size 3 inserts.
