Kennametal 1796179 Threading Insert KC5025 8 Tpi Left Hand

Product Description

The KENNAMETAL 1796179 is a carbide threading insert designed for external thread cutting on UNJ-standard threads at 8 TPI. Part of the Top Notch series, it features a TiAlN finish applied via PVD coating, which improves wear resistance and tool life during threading operations. The insert uses a left-hand orientation with a 60-degree included angle, an insert size of 3020, and an NJP insert style. It is installed by machinists and CNC turning specialists working with precision threaded components where UNJ thread form compliance is required.

This insert is suited for external threading operations on materials in the C2 and C6 material grade classifications. The Top Notch series design makes it a fit for indexable threading toolholders that accept the NJP insert style. It is commonly used in production machining environments where consistent thread form, tight tolerances, and surface finish on external UNJ threads are priorities. The KC5025 grade is formulated for threading applications that demand toughness combined with wear resistance.

Installation Notes

Threading inserts of this type are installed and indexed by machinists or tooling technicians on CNC or manual turning equipment. Ensure the machine spindle is fully stopped and the toolholder is secured before seating or indexing the insert. Use the appropriate torque wrench for the clamping screw to avoid seat damage. Verify insert orientation and hand designation against the toolholder specification before engaging the cut.
