Vargus 80492 Carbide Thread Mill Insert 20 Tpi Un

Product Description

The VARGUS 80492 is a carbide thread mill insert designed for internal UN thread milling operations. Finished with a TiAlN PVD coating, this insert delivers thermal resistance and wear performance suited to non-ferrous and general-purpose workpiece materials. The insert style is R25I with a size code of 25 and a manufacturer grade of VTX. It threads at 20 TPI, conforming to ANSI B1.1:74, making it appropriate for standard unified thread form production. CNC machinists and toolroom programmers install this insert into compatible VARGUS thread mill bodies for precision internal threading on machining centers.

This insert is used in internal thread milling applications on CNC machining centers and mill-turn platforms. It targets unified national thread forms at 20 TPI in non-ferrous workpiece materials. The TiAlN PVD coating supports dry or semi-dry cutting strategies. Typical applications include threaded hole production in aluminum, brass, and similar materials where thread quality and tool life consistency are critical to cycle time and part conformance.

Key Features

• Carbide substrate with VTX manufacturer grade for wear resistance
• TiAlN PVD coating for thermal and oxidation resistance
• R25I insert style at size code 25 for compatibility with matching thread mill bodies
• 20 TPI internal UN thread form per ANSI B1.1:74
• Optimized for non-ferrous workpiece materials (Material Code N)

Compatibility

Designed as an OEM-style replacement insert for VARGUS R25I thread mill bodies requiring internal UN 20 TPI carbide inserts with VTX grade and TiAlN coating.

Installation Notes

Thread mill inserts are installed and torqued by CNC machinists according to the tool body manufacturer specifications - consult the VARGUS tool body documentation for seat and clamping requirements. Power down and lock out the spindle before changing inserts. Handle carbide inserts with care to avoid edge chipping. Verify insert orientation and seating before resuming cutting operations.
