Kennametal 1795799 Threading Insert 16 Tpi KC5025 Carbide

Product Description

The KENNAMETAL 1795799 is a carbide threading insert designed for external thread cutting operations. It carries the NJP style designation in the Top Notch series and is manufactured to KENNAMETAL grade KC5025 with a TiAlN finish applied via PVD coating. The insert produces UNJ-standard external threads at 16 TPI with a 60-degree included angle. It is a right-hand insert sized at 3010, measuring 0.1949 inches thick with a corner radius of 0.0098 inches. Machinists and CNC turning specialists install this insert in compatible Top Notch threading toolholders for precision external thread milling on aerospace and general industrial workpieces.

This insert is suited for external threading applications where tight tolerances and a controlled corner radius are required. The UNJ thread standard, which specifies a controlled root radius, makes this insert appropriate for aerospace fastener and component threading where fatigue resistance in the finished thread is a priority. The KC5025 grade with TiAlN coating provides wear resistance and thermal stability at elevated cutting speeds, making it a practical choice for interrupted cuts and difficult-to-machine alloys encountered in production turning environments.

Compatibility

Designed for use with KENNAMETAL Top Notch series threading toolholders that accept NJP-style inserts in size 3010. Verify toolholder pocket specifications before installation.

Installation Notes

Threading inserts of this type are installed and replaced by machinists or CNC lathe operators. Power down and lock out the machine before changing inserts. Use the appropriate torque wrench and insert clamp hardware specified by the toolholder manufacturer to secure the insert. Handle carbide inserts with care to avoid chipping the cutting edge prior to use.
