Kennametal 1799469 Threading Insert KC5025 Acme 3 Tpi

Product Description

The KENNAMETAL 1799469 is a carbide threading insert designed for cutting Acme thread forms on both internal and external workpieces. Manufactured to the Top Notch series standard, this insert carries the KC5025 grade designation with a TiAlN finish applied via a PVD coating process. The KC5025 grade is engineered for threading applications where wear resistance and edge integrity are critical. With a 29-degree included angle and an internal pitch rating of 3 TPI, this right-hand insert is suited for production threading on CNC lathes and manual turning centers. It is installed by machinists and toolroom professionals working in metal-cutting environments.

This insert is used in Acme thread-form applications across both internal and external threading operations. The Top Notch series toolholder system accepts this insert size 6 profile. Typical installation scenarios include threading lead screws, power transmission components, and other Acme-profile workpieces in job shop and production machining environments. The right-hand configuration suits standard feed-direction turning setups. The TiAlN PVD coating provides thermal resistance suitable for a range of workpiece materials corresponding to material grades C2 and C6.
