Product Description

The VARGUS 80518 is a carbide thread mill insert designed for both internal and external NPT thread milling at 11.5 teeth per inch. Manufactured from micrograin carbide and finished with a TiAlN coating applied via PVD process, this insert carries the VTX manufacturer grade and is part of the Standard MiTM series. It is rated for use on superalloy and titanium workpiece materials, making it a fit for demanding metalworking environments. The insert style is R25EI with a size code of 25. Licensed machinists and CNC tooling specialists install and index these inserts as part of thread milling tooling systems.

This insert is suited for NPT thread milling operations on superalloy and titanium workpieces in precision machining environments. The internal and external thread capability at 11.5 TPI makes it applicable to a range of pipe thread applications conforming to USAS B2.1:1968. It is packaged individually and sold in a minimum order quantity of 2 units, making it a replacement-style insert for ongoing production or maintenance tooling programs.

Installation Notes

Thread mill inserts should be installed and indexed by a qualified machinist or CNC tooling technician. Ensure the spindle is fully stopped and the machine is locked out before replacing or indexing any insert. Use the appropriate torque wrench and insert screw driver specified by the toolholder manufacturer to seat the insert securely without over-torquing. Inspect the seating pocket for chips or debris before installation to ensure proper insert registration.
