Kennametal 1799604 Threading Insert KC5025 4-6 Tpi

Product Description

The KENNAMETAL 1799604 is a carbide threading insert in the Top Notch series, designed for cutting American Buttress threads on metalworking lathes and threading machines. It carries the KC5025 manufacturer grade with a PVD-applied TiAlN finish, which provides wear resistance and thermal stability during threading operations. The insert handles both internal and external thread forms at 4 to 6 TPI and is configured for right-hand cutting. With an included angle of 45 degrees and a corner radius of 0.0098 inches, it is suited for precision buttress-thread profiles in production and maintenance machining environments. Installation is performed by qualified machinists and tool-room personnel.

This insert is used in threading operations where American Buttress thread forms are required, including applications in power transmission, hydraulic cylinders, and heavy mechanical assemblies. The right-hand orientation and 4 to 6 TPI pitch range make it applicable to both internal bore threading and external turning operations. It fits toolholders compatible with the Top Notch insert system and is appropriate for use on CNC lathes and manual threading equipment in industrial machining settings.

Installation Notes

Installation should be performed by a qualified machinist or tool-room technician. Ensure the machine spindle is fully stopped and locked out before changing inserts. Seat the insert firmly in the toolholder pocket and verify the clamping screw torque is appropriate for the holder manufacturer's specification. Inspect the insert seat and clamp for wear or debris before each use to maintain thread form accuracy.
