Kennametal 1796526 Threading Insert NAS3R10 KC5010 Carbide

Product Description

The KENNAMETAL 1796526 is a carbide threading insert in the Top Notch series, designed for cutting Stub Acme threads at 10 TPI with a 29-degree included angle. The insert carries a TiAlN finish applied via PVD coating process, which delivers elevated wear resistance and thermal hardness for demanding threading operations. Rated at material grades C3 and C4, it handles a broad range of ferrous and non-ferrous workpiece materials. Machining professionals and CNC lathe operators use this insert in both internal and external threading applications where precise Stub Acme profile geometry and consistent tool life are required.

This insert is suited for both internal and external Stub Acme threading applications on CNC lathes and manual turning centers. The right-hand configuration and NAS insert style make it a direct fit for compatible Top Notch toolholders. It is appropriate for production environments machining medium to hard workpiece materials requiring a controlled thread form, including repair shops and production facilities cutting power-transmission thread forms on leadscrews, jacks, and actuator components.

Installation Notes

Threading inserts of this type are installed and exchanged by machinists or toolroom technicians following standard insert-change procedures. Ensure the machine spindle is fully stopped and power is locked out before handling or replacing the insert. Use the appropriate torx or hex key to the toolholder manufacturer's specified seating procedure to secure the insert without damaging the carbide. Inspect the insert pocket and clamping components for wear or debris before seating a replacement insert.
