Finished with a Titanium Nitride (TiN) PVD coating, this right-hand insert handles external pitches from 0.70 to 3.00 mm (8 to 36 TPI) and internal pitches from 1.25 to 3.50 mm (7 to 20 TPI). The included angle is 60 degrees, making it suited for partial profile unified and metric thread forms. It carries a manufacturer grade of KC730 and material grades C2, C3, and C4. Machinists and CNC tooling technicians install this insert in compatible Top Notch toolholders for precision threading on lathes and turning centers.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in metalworking environments where consistent thread quality is required across a range of pitches. The NTP2R style supports both internal and external applications in a single insert geometry, reducing tooling changeovers on the shop floor. It is appropriate for production and job-shop turning operations on ferrous and non-ferrous materials within the C2 through C4 material grade range. The insert size is 2, fitting standard Top Notch series toolholders designed for that insert size class.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbide substrate with PVD Titanium Nitride (TiN) finish for wear resistance\u003c\/li\u003e\n  \u003cli\u003eExternal pitch range: 0.70 to 3.00 mm (8 to 36 TPI)\u003c\/li\u003e\n  \u003cli\u003eInternal pitch range: 1.25 to 3.50 mm (7 to 20 TPI)\u003c\/li\u003e\n  \u003cli\u003ePartial profile 60-degree thread form for unified and metric thread cutting\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction, insert size 2\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.1 mm (0.004 inches) for controlled thread root geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Top Notch series toolholders that accept size 2 NTP-style threading inserts.
