Kennametal 1796500 Threading Insert Size 3 KC5025 Carbide

Product Description

The KENNAMETAL 1796500 is a carbide threading insert designed for precision thread cutting in metalworking and machining applications. Manufactured to the NA style in size 3, it carries the KC5025 grade with a TiAlN finish applied via PVD coating process. This insert cuts Acme thread forms at 12 threads per inch (TPI) with a 29-degree included angle, handling both internal and external thread profiles in a left-hand orientation. The KC5025 carbide substrate offers wear resistance suited to interrupted cuts and difficult materials. Machinists and CNC operators working with threading toolholders in the Top Notch series will find this insert a direct fit for production and repair threading work.

This insert is intended for use in threading operations on lathes and CNC turning centers where Acme thread forms are required. The left-hand configuration makes it appropriate for left-hand threaded spindles, lead screws, and similar components. With the ability to cut both internal and external threads, it suits a range of workpiece configurations. The TiAlN PVD coating supports performance in dry and semi-dry cutting environments. It is typically installed by machinists and tool-and-die professionals working in manufacturing, maintenance, and repair settings.

Installation Notes

Threading inserts of this type are installed and changed by qualified machinists or CNC operators. Power down and lock out the machine before seating or removing any insert. Use the correct torque driver or wrench for the clamping screw - do not overtighten by hand estimation alone. Inspect the toolholder pocket for chips or damage before seating the insert, and confirm the insert is fully engaged before resuming cutting operations.
