Kennametal 1796106 Threading Insert NTP3R KC5025 Carbide

Product Description

The KENNAMETAL 1796106 is a carbide threading insert in the Top Notch series, designed for both internal and external thread cutting operations. It carries the KC5025 manufacturer grade with a TiAlN finish applied via PVD coating process, providing wear resistance in demanding threading applications. The insert is configured for right-hand cutting with a partial profile 60-degree thread standard. External pitch range covers 1.25 to 4.00 mm and 6 to 20 TPI. Internal pitch range covers 2.00 to 5.00 mm and 5 to 12 TPI. This insert is used by machinists and toolroom technicians in CNC lathe and manual turning center applications.

This threading insert is suited for production and job shop environments where consistent thread form and tool life are critical. It handles both internal and external threading on a single geometry, reducing tooling inventory. The 60-degree included angle covers Unified, Metric, and similar thread forms. The PVD TiAlN coating supports cutting in steels and other materials requiring material grades C2 through C6. Insert size 3 fits standard Top Notch style toolholders used in turning centers and engine lathes.

Installation Notes

Threading inserts of this type are seated and secured by a machinist or toolroom technician familiar with indexable insert tooling systems. Ensure the machine spindle is fully stopped and the toolholder is clear of the workpiece before indexing or replacing the insert. Verify insert seating and clamp engagement before resuming cuts. Follow the toolholder manufacturer torque guidance for the clamping screw and inspect the insert pocket for debris or damage prior to installation.
