Vargus 65122 Carbide Thread Mill Insert 8 Tpi Un

Product Description

The VARGUS 65122 is a carbide thread mill insert designed for external UN thread milling operations at 8 threads per inch (TPI). Built to Insert Style 5E with a 5/8-inch inscribed circle, this insert carries a TiAlN finish applied via PVD coating process. The micrograin carbide substrate and VTX manufacturer grade support consistent performance in demanding cutting environments. It is installed in compatible thread mill holders and is typically handled by machinists and tooling specialists in production or job-shop settings.

This insert is suited for external thread milling on non-ferrous metals, superalloys, and titanium workpieces. The 8 TPI configuration targets standard UN thread profiles per ANSI B1.1:74. With a series designation of Standard TM and a primary workpiece material code of N, the 65122 is matched to applications where edge retention and coating adhesion under high-temperature cutting conditions are priorities. It is sold individually with a minimum order quantity of 5 units.

Installation Notes

Thread mill inserts should be seated and torqued according to the tool holder manufacturer specifications using the appropriate insert screw and wrench. Ensure the spindle is fully stopped and the machine is locked out before changing inserts. Verify thread profile and TPI against the workpiece drawing prior to first use. Improper seating or a damaged insert pocket can cause insert movement and thread form errors.
