It carries the KC730 manufacturer grade with a Titanium Nitride (TiN) finish applied via PVD coating process. This insert covers a partial profile 60-degree thread form, handling external pitches from 1.25 to 6.25 mm (4 to 20 TPI) and internal pitches from 2.00 to 6.25 mm (4 to 12 TPI). It belongs to Kennametal's Top Notch series and is installed by machinists and CNC lathe operators in production and job-shop threading operations.\u003c\/p\u003e\u003cp\u003eThis insert is suited for threading operations on steel, cast iron, and non-ferrous materials classified under material grades C2, C3, and C4. The Top Notch series is a common tooling platform used in both manual and CNC turning centers for external and internal thread profiles. The 60-degree included angle makes it compatible with standard UN, metric, and similar thread forms requiring a partial profile geometry. It is appropriate for low-to-medium cutting speeds typical of carbide PVD-coated tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eNT4L insert style in the Top Notch series toolholder platform\u003c\/li\u003e\n\u003cli\u003eKC730 carbide grade with PVD-applied Titanium Nitride finish for wear resistance\u003c\/li\u003e\n\u003cli\u003ePartial profile 60-degree thread form for internal and external use\u003c\/li\u003e\n\u003cli\u003eLeft-hand cutting orientation\u003c\/li\u003e\n\u003cli\u003eExternal pitch range: 1.25 to 6.25 mm (4 to 20 TPI)\u003c\/li\u003e\n\u003cli\u003eInternal pitch range: 2.00 to 6.25 mm (4 to 12 TPI)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series toolholders accepting NT insert style.
