Kennametal 1796202 Threading Insert 18 Tpi KC5010 Tialn

Product Description

The KENNAMETAL 1796202 is a carbide threading insert designed for external thread cutting operations. Carrying the NJF3009R18 designation within the Top Notch series, this insert features a KC5010 manufacturer grade with a TiAlN finish applied via PVD coating. It is engineered for right-hand external threading at 18 TPI on UNJ thread standards with a 60-degree included angle. The insert measures 0.1949 inches thick and has a tip-to-top dimension of 0.1409 inches with a corner radius of 0.0087 inches. Machinists and CNC operators working in aerospace, defense, and precision manufacturing environments will find this insert suited to demanding external thread-cutting applications.

This insert is intended for use in external threading operations where UNJ thread form accuracy is required. The UNJ standard is commonly specified in aerospace and high-strength fastener applications. The Top Notch series tooling system is a quick-change, indexable threading platform. The KC5010 grade and TiAlN PVD coating combination is suited to threading hardened steels and difficult-to-machine alloys at controlled cutting speeds, making it a practical choice for production threading in machine shops and aerospace component manufacturing environments.

Key Features

• NJF insert style in the Top Notch series for quick-change indexable threading setups
• KC5010 carbide grade with TiAlN finish via PVD coating for wear resistance on difficult alloys
• 18 TPI external thread pitch for UNJ thread standard applications
• Right-hand cut orientation with a 60-degree included angle
• Corner radius of 0.0087 inches for controlled thread form accuracy
• Insert size 3009 with a thickness of 0.1949 inches

Compatibility

Designed as an OEM-style replacement threading insert for KENNAMETAL Top Notch series external threading toolholders accepting NJF-style inserts.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the toolholder is properly seated and torqued before beginning a threading pass. Index or replace the insert when thread form quality degrades rather than continuing to cut, as worn inserts compromise thread accuracy. Follow the toolholder manufacturer guidelines for proper insert seating and clamping within the Top Notch system.
