Kennametal 1114378 Threading Insert 24 Tpi KC730 Carbide

Product Description

The KENNAMETAL 1114378 is a carbide threading insert designed for external thread cutting on precision machined components. Featuring a Titanium Nitride (TiN) finish applied via PVD coating process, this insert carries the KC730 manufacturer grade and is rated for material grades C2, C3, and C4. It cuts right-hand external threads to the UNJ thread standard at 24 threads per inch (TPI) with a 60-degree included angle. The NJK insert style seats in Top Notch series toolholders. With a corner radius of 0.0068 inches and a tip-to-top height of 0.1409 inches, it is built for controlled thread form accuracy in production turning environments. Machinists and CNC operators in aerospace, defense, and precision manufacturing install this type of insert.

This insert is suited for external threading operations on lathes and turning centers where UNJ thread profiles are required. The KC730 grade with PVD TiN coating provides wear resistance when threading steels and other materials in the C2 through C4 material grade range. It is commonly used in job shops and production facilities running Top Notch compatible tooling systems that demand consistent thread geometry and repeatable insert seating across high-volume runs.

Installation Notes

Threading inserts should be installed by qualified machinists or CNC operators following the toolholder manufacturer's clamping torque and seating procedures. Power down and lock out the machine spindle before changing inserts. Inspect the insert pocket for chips or debris before seating the new insert. Follow applicable shop safety procedures and machine guarding requirements during insert changes.
