Kennametal 1796505 Threading Insert 8 Tpi Acme KC5010

Product Description

The KENNAMETAL 1796505 is a carbide threading insert designed for Acme thread forms at 8 threads per inch (TPI). Part of the Top Notch series, it features a TiAlN finish applied via PVD coating, which provides elevated heat resistance and extended tool life in demanding threading operations. The insert carries a 29-degree included angle and a 0.0050-inch corner radius, making it suited for precision internal and external Acme thread cutting. It is handled and installed by machinists and CNC tooling specialists in production and job-shop environments where thread accuracy and insert consistency are critical.

This insert is applicable to both internal and external threading operations on Acme thread profiles. The right-hand configuration and 8 TPI pitch make it a direct fit for applications requiring standard Acme thread geometry. It is used in turning centers and manual lathes equipped with Top Notch compatible toolholders. Typical applications include lead screw production, power transmission components, and other precision threaded workpieces where Acme thread form accuracy is required.
