Manufactured in the NT3R style and running the KC850 grade substrate, this insert carries a CVD-applied TiC\/TiCN\/TiN multilayer coating that resists wear and heat during continuous threading passes. It covers a partial profile 60-degree thread form, handling external pitches from 1.25 to 4.00 mm (6 to 20 TPI) and internal pitches from 2.00 to 5.00 mm (5 to 12 TPI). It is a right-hand insert belonging to the Top Notch series and is suited for CNC lathes and manual turning centers used in production threading applications.\u003c\/p\u003e\n\u003cp\u003eThis insert is used in metalworking environments where reliable, repeatable thread profiles are required across a range of pitch sizes. Typical applications include threading operations on steel, stainless, and cast iron workpieces classified under material grades C5 and C6. The Top Notch series toolholding system is the intended platform for this insert. Machinists and CNC operators in job shops, production facilities, and maintenance-repair-overhaul environments use this insert for both internal bore threading and external OD threading work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKC850 carbide grade with CVD TiC\/TiCN\/TiN multilayer coating for extended tool life\u003c\/li\u003e\n  \u003cli\u003ePartial profile 60-degree thread form covers both internal and external thread applications\u003c\/li\u003e\n  \u003cli\u003eExternal pitch range: 1.25 to 4.00 mm (6 to 20 TPI)\u003c\/li\u003e\n  \u003cli\u003eInternal pitch range: 2.00 to 5.00 mm (5 to 12 TPI)\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting geometry, NT insert style, Insert Size 3\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.17 mm (0.0067 inches) for controlled thread root form\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Top Notch series threading toolholders that accept NT-style inserts.
