Kennametal 1796504 Threading Insert KC5025 Acme 10 Tpi

Product Description

The KENNAMETAL 1796504 is a carbide threading insert designed for cutting Acme thread forms on both internal and external workpieces. Manufactured to the NA3L10 style in the Top Notch series, this left-hand insert carries a KC5025 grade designation and a PVD-applied TiAlN finish that improves wear resistance and thermal stability during threading operations. The cutting tip measures 0.0319 inches wide with a tip-to-top height of 0.1492 inches, and the insert body thickness is 0.1949 inches. It is suited for CNC lathes and manual turning centers where consistent thread geometry is required on Acme-profile applications. Machinists and toolroom technicians working in metalworking and precision machining environments are the primary installers.

This insert is intended for Acme thread cutting at 10 TPI with a 29-degree included angle. The left-hand orientation makes it appropriate for left-hand thread applications on shafts, lead screws, and actuator components. Its Top Notch series designation indicates compatibility with Top Notch-style toolholders that accept size 3 inserts. The KC5025 grade with TiAlN coating performs well across a range of material grades classified as C2 and C6, covering a broad spectrum of ferrous and non-ferrous materials typical in production and job-shop threading work.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians on properly secured CNC or manual turning equipment. Power down and lock out the machine spindle before seating or replacing any insert. Ensure the toolholder pocket is clean and free of chips before installing the insert to maintain correct seating and thread geometry. Follow the toolholder manufacturer's clamping torque specifications for Top Notch-style insert retention hardware.
