Kennametal 1796177 Threading Insert 8 Tpi Carbide Tialn

Product Description

The KENNAMETAL 1796177 is a carbide threading insert designed for external thread-cutting operations on CNC lathes and turning centers. Manufactured in the NJP insert style with a KC5025 grade carbide substrate and a PVD-applied TiAlN finish coating, this insert delivers reliable performance in threading applications requiring tight tolerances. It cuts at 8 threads per inch (TPI) with a 60-degree included angle, conforming to the UNJ thread standard. The insert measures 0.1949 inches thick and carries a corner radius of 0.0193 inches. It is part of the Top Notch series and is intended for installation and use by machinists and CNC tooling technicians.

This insert is suited for external threading on ferrous and aerospace-grade materials where the UNJ thread form is specified. The KC5025 grade with TiAlN PVD coating is formulated for use in interrupted cuts and difficult-to-machine alloys. Right-hand cutting orientation makes it compatible with standard right-hand turning setups. The Top Notch series toolholder system is the intended mounting platform for this NJP-style insert.

Installation Notes

Threading inserts of this type are installed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or removing any insert. Use the appropriate torx or hex key to the toolholder manufacturer's specified clamping procedure. Inspect the insert pocket and clamping screw for wear or damage before installing a replacement insert.
