Kennametal 1796519 Threading Insert KC5010 Carbide Tialn

Product Description

The KENNAMETAL 1796519 is a carbide threading insert designed for cutting Acme threads on both internal and external workpieces. It carries the KC5010 manufacturer grade and is finished with a TiAlN PVD coating, which improves wear resistance and heat tolerance during threading operations. The insert belongs to the Top Notch series and is configured for left-hand thread cutting at 4 threads per inch (TPI) with a 29-degree included angle. Machinists and toolroom operators use this insert in CNC lathes and manual turning centers where consistent Acme thread profiles are required.

This insert is suited for machining operations that demand accurate Acme thread geometry in both internal and external applications. The left-hand orientation makes it appropriate for spindles, lead screws, and actuator components requiring reverse-direction threading. The KC5010 grade with PVD TiAlN coating performs well across C3 and C4 material grades, including cast iron, hardened steels, and similar materials common in industrial and motion-control component manufacturing. It is a single-sided insert sized at Insert Size 3 within the Top Notch platform.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer guidelines for Top Notch series inserts. Power down and de-energize the machine spindle completely before seating or replacing any insert. Use the correct torque driver specified by the toolholder manufacturer to avoid cracking the carbide body. Verify thread pitch and hand orientation against the workpiece drawing before engaging the cutting pass.
