Kennametal 1796048 NT2L KC5025 Threading Insert

Product Description

The KENNAMETAL 1796048 is a carbide threading insert designed for precision thread cutting on both internal and external workpieces. Manufactured in the NT2L style with a KC5025 grade substrate and a PVD-applied TiAlN finish, this insert delivers wear resistance suited to a range of ferrous and non-ferrous materials. It produces a partial profile 60-degree thread form and is configured for left-hand thread cutting. The insert seats in Top Notch series toolholders and is a common choice for machinists and toolroom technicians working on CNC lathes and manual turning centers.

This insert is suited for threading operations in production and job-shop environments where consistent thread form and tool life are priorities. The external pitch range of 0.70 to 3.00 mm (8 to 36 TPI) and internal pitch range of 1.25 to 3.50 mm (7 to 20 TPI) make it applicable across a broad spectrum of thread sizes. It is appropriate for use on steel, cast iron, and similar materials classified under material grades C2 and C6.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Disengage all machine drives and confirm the spindle is fully stopped before indexing or replacing the insert. Use the appropriate torx or hex key to secure the insert clamp to the manufacturer-recommended seating method for Top Notch toolholders. Inspect the insert pocket and seating surface for chips or debris before installation to ensure proper insert contact and thread accuracy.
