Kennametal 1796509 Threading Insert KC5010 6 Tpi Acme

Product Description

The KENNAMETAL 1796509 is a carbide threading insert designed for precision thread-cutting operations on both internal and external Acme threads. Manufactured to the NA3R6 insert style, it carries the KC5010 grade designation and features a Physical Vapor Deposition (PVD)-applied TiAlN finish for enhanced wear resistance and thermal stability. The insert runs at 6 threads per inch (TPI) with a 29-degree included angle, suiting it to Acme thread-form applications. Size 3 geometry, a tip-to-top height of 0.1492 inches, and a corner radius of 0.057 inches make it a precise fit for Top Notch series toolholders. Licensed machinists and CNC turning specialists are the primary users.

This insert is suited for shops running Acme thread forms on lathes or CNC turning centers in both production and maintenance environments. Right-hand cutting geometry makes it appropriate for standard right-hand Acme thread applications. The TiAlN coating supports use in a range of workpiece materials, including steels and cast irons commonly associated with C3 and C4 material grade classifications. Internal and external thread compatibility provides flexibility across different part geometries without requiring a separate insert grade.

Installation Notes

Installation should be performed by a qualified machinist or tooling specialist. Ensure the lathe or turning center is fully powered down and the spindle is locked before seating or removing inserts. Use the appropriate torque wrench and Kennametal-specified clamp screws to secure the insert without over-torquing the clamping mechanism. Verify insert seating and tool stick-out against your setup sheet before running the first thread pass.
