Kennametal 1114946 Threading Insert NJP3020R8 KC850 8 Tpi

Product Description

The KENNAMETAL 1114946 is a carbide threading insert designed for external thread cutting operations. Manufactured in the NJP insert style and offered in the KC850 grade, it carries a CVD-applied TiC/TiCN/TiN multilayer finish that provides wear resistance and thermal protection during high-speed threading. The insert is configured for right-hand cutting at 8 threads per inch (TPI) with a 60-degree included angle, making it suited to UNJ thread standard applications. Licensed machinists and CNC lathe operators working in aerospace, defense, or precision manufacturing environments are the primary users of this insert.

This insert fits the Top Notch series toolholding system and is intended for external threading on workpieces requiring UNJ thread forms. The KC850 carbide grade, rated at material grades C5 and C6, performs well in interrupted cuts and on a range of ferrous materials. It is sold individually per package with a minimum order quantity of 5 units, which aligns with typical shop floor and production stocking practices.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before changing or indexing inserts. Use the appropriate torx or clamping screw driver specified by the toolholder manufacturer to secure the insert — do not overtighten. Inspect the insert pocket and clamping mechanism for wear or debris before seating a new insert.
