Vargus 80519 Carbide Thread Mill Insert 11.5 Tpi Npt

Product Description

The VARGUS 80519 is a carbide thread mill insert designed for cutting NPT (National Pipe Taper) threads at 11.5 threads per inch (TPI), suitable for both internal and external thread milling applications. The insert carries a TiAlN finish applied via PVD coating, which provides thermal resistance and extended tool life in demanding cutting conditions. Designated insert style R25EI with size code 25, this insert is engineered to manufacturer grade VTX. It is used by machinists and tool and die professionals working with CNC thread milling operations where NPT pipe thread forms are required.

This insert is intended for thread milling operations on pipe fittings, valves, manifolds, and other components requiring NPT thread forms conforming to USAS B2.1:1968. It is suited for use with compatible VARGUS thread mill bodies in production and maintenance machining environments. The primary workpiece material code P indicates suitability for steel and similar ferrous materials. Both internal and external thread milling at 11.5 TPI NPT are within the designed application range of this insert.

Installation Notes

Installation of this insert should be performed by a qualified machinist following the tool body manufacturer guidelines for insert seating and clamping. Power down and lock out the CNC machine before changing inserts. Inspect the insert pocket and clamping screw for wear or damage before seating a new insert. Do not force the insert into the pocket; proper seating ensures accurate thread form and tool life.
