Kennametal 1796084 Threading Insert NT3L KC5025 Tialn

Product Description

The KENNAMETAL 1796084 is a carbide threading insert in the NT3L style, engineered for precise thread-cutting on both internal and external workpieces. It carries a TiAlN finish applied via PVD coating, which improves wear resistance and thermal stability during high-speed threading operations. The insert is designed for a 60-degree partial profile thread form and is suited for left-hand thread applications. It falls within the Top Notch series and is specified at Insert Size 3, with a tip-to-top height of 0.098 inches (2.49 mm) and a corner radius of 0.0067 inches (0.17 mm). Machinists and tooling specialists working in production or job-shop environments are the primary users.

This insert handles both internal and external threading across a broad pitch range. External pitch coverage runs from 1.25 to 4.00 mm (6 to 20 TPI), and internal pitch coverage runs from 2.00 to 5.00 mm (5 to 12 TPI). The 60-degree included angle makes it suitable for unified and metric thread standards on a partial-profile basis. Typical applications include threading steel, stainless, and similar materials where consistent tool life and thread quality are required in turning center or lathe operations.

Compatibility

Designed for use in Top Notch series threading toolholders that accept NT Insert Style inserts at Insert Size 3. Verify toolholder specifications before ordering to confirm proper seating and clamping.

Installation Notes

Insert installation should be performed by a qualified machinist or tooling technician with the machine in a powered-down, locked-out state. Use the correct torque wrench and clamping screw specified for the Top Notch toolholder to seat the insert properly - do not overtighten by hand estimation alone. Inspect the insert pocket for chips or debris before seating the new insert. Replace the insert at first signs of flank wear or thread form degradation to maintain part quality.
