Kennametal 1796156 Threading Insert NTK2R KC5010 Carbide

Product Description

The KENNAMETAL 1796156 is a carbide threading insert designed for precision thread-cutting operations on both internal and external workpieces. Manufactured to the NTK2R insert style and offered in the KC5010 grade with a PVD-applied TiAlN finish, this insert is engineered for the Top Notch series tooling system. It handles a partial profile 60-degree thread standard and covers an external pitch range of 0.60 to 1.75 mm (14 to 44 TPI) and an internal pitch range of 1.00 to 2.00 mm (12 to 24 TPI). It is installed by machinists and CNC tooling technicians in production and job-shop environments.

This insert is suited for threading operations on lathes and turning centers in both light and medium-duty applications. The right-hand configuration and 60-degree included angle make it a practical choice for general-purpose unified and metric thread profiles. The TiAlN coating supports performance in ferrous and hard materials. It fits into the Top Notch series insert holders and is sized as an Insert Size 2 for direct compatibility with that toolholder family.

Installation Notes

Threading inserts of this type are installed and replaced by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or removing any insert. Ensure the insert pocket and clamping surfaces are clean and free of chips before installation. Follow the toolholder manufacturer torque specifications for the clamping screw to avoid insert movement or breakage during the threading pass.
