Kennametal 1796180 Threading Insert 12 Tpi KC5010 Carbide

Product Description

The KENNAMETAL 1796180 is a carbide threading insert in the Top Notch series, designed for external thread turning on CNC lathes and turning centers. Manufactured to the NJP insert style with a KC5010 grade substrate and a PVD-applied TiAlN finish coating, this insert is engineered for right-hand external threading of UNJ-standard threads at 12 TPI. The 60-degree included angle suits unified thread-form geometry, and the TiAlN coating provides elevated wear resistance and heat resistance in demanding threading operations on aerospace-grade and hardened materials. The insert mounts in compatible Top Notch toolholders and is sold individually with a minimum order quantity of 5 units.

This insert is suited for external threading applications in precision machining environments, including aerospace, defense, and general metalworking shops. The UNJ thread standard designation makes it appropriate for applications requiring controlled root radius threads for fatigue-critical fasteners and aerospace hardware. It is typically installed by CNC machinists and tool-and-die professionals on production lathes and multi-axis turning centers where consistent thread geometry and insert repeatability are required across high-volume runs.

Key Features

• KC5010 carbide grade with PVD TiAlN coating for wear and heat resistance in threading operations
• NJP insert style in the Top Notch series for use with compatible Top Notch threading toolholders
• 12 TPI external pitch with 60-degree included angle for unified thread-form geometry
• UNJ thread standard - radius root form for fatigue-critical aerospace and defense applications
• Right-hand cutting configuration for standard external threading on CNC lathes and turning centers
• Corner radius of 0.013 inches (0.33 mm) for controlled thread root profile

Compatibility

Designed for use with KENNAMETAL Top Notch series threading toolholders accepting NJP-style inserts. Verify toolholder seat geometry and insert size 3014 compatibility before installation.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling technician. Power down and lock out the machine spindle before seating or replacing the insert. Use the correct torque wrench and manufacturer-specified clamping hardware for the Top Notch toolholder to avoid insert rocking or improper seating. Inspect the insert pocket for chips or debris before mounting, and confirm thread pitch and hand orientation match the workpiece requirements before initiating a threading pass.
