Vargus 80500 Carbide Thread Mill Insert 12 Tpi Un

Product Description

The VARGUS 80500 is a carbide thread mill insert designed for internal UN thread milling applications. Finished with a PVD-applied TiAlN coating and manufactured to the VTX grade standard, this insert delivers consistent thread form and extended tool life in demanding machining environments. Rated at 12 threads per inch, it conforms to ANSI B1.1:74 standards for Unified National thread profiles. The insert style is R25I with an insert size code of 25. Machinists, toolroom operators, and CNC programmers working with internal threading operations will find this insert a direct-fit consumable for compatible thread mill bodies.

This insert is suited for internal thread milling of UN-profile threads at 12 TPI in machining centers and CNC mills. The TiAlN coating is well matched to a range of workpiece materials, with the primary workpiece material code N indicating suitability for non-ferrous and similar material groups. Typical applications include production threading of bored holes in parts requiring Unified National thread forms. This is a replacement-style insert intended for use in compatible R25I-style thread mill tooling systems.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist or toolroom technician using the torque specifications provided by the thread mill body manufacturer. Ensure the spindle is fully stopped and the machine is in a safe state before changing inserts. Inspect the insert pocket for debris or damage prior to seating the new insert. Follow the tooling system manufacturer guidelines for insert indexing and clamping screw tightening sequence.
