Kennametal 1796411 Threading Insert 16 Tpi KC5010 Carbide

Product Description

The KENNAMETAL 1796411 is a carbide threading insert designed for external thread cutting operations. Manufactured in the NJK style with a KC5010 grade substrate and a PVD-applied TiAlN finish, this insert delivers wear resistance suited to demanding threading applications. It is ground to cut at 16 TPI with a 60-degree included angle and a right-hand cutting orientation. The Top Notch series designation indicates compatibility with KENNAMETAL Top Notch toolholders. Licensed machinists and CNC lathe operators use this insert for precision external threading on aerospace and industrial components held to UNJ thread standards.

This insert is intended for external UNJ thread profiles at 16 TPI. The UNJ thread standard, which specifies a controlled root radius, is common in aerospace and defense manufacturing where fatigue resistance is critical. The NJK insert style and KC5010 grade are suited for threading operations on steels and other materials classified under material grades C3 and C4. It is installed in compatible Top Notch series threading toolholders and used on CNC lathes or manual turning centers where consistent thread form and tool life are required.

Installation Notes

Installation is performed by licensed machinists or qualified CNC tooling technicians. Ensure the machine spindle is fully stopped and the toolholder is secured in the turret before seating or replacing the insert. Use the correct torque wrench and insert screw specified by the toolholder manufacturer - do not overtighten the clamping screw. Verify insert seating and thread pitch with a thread gauge before running production parts.
