Vargus 80496 Carbide Thread Mill Insert Un 16 Tpi

Product Description

The VARGUS 80496 is a carbide thread mill insert designed for internal UN thread milling operations at 16 threads per inch. Finished with a TiCN coating applied via PVD process, this insert delivers wear resistance and thermal stability suited to demanding thread milling applications. The R25I insert style seats into compatible thread mill toolholders and produces accurate internal UN thread forms to ANSI B1.1:74 standards. Installation and operation are handled by machinists and CNC toolroom personnel working with threading programs on milling centers.

This insert is configured for internal thread milling on UN unified thread forms at 16 TPI. It is suited for use on non-ferrous and similar workpiece materials as indicated by the primary workpiece material code. Typical applications include producing internal threaded features in parts where single-point threading or tapping is not practical, or where thread quality and repeatability are priorities in a CNC milling environment.

Key Features

• Carbide substrate for rigidity and wear life in thread milling operations
• TiCN coating via PVD process for improved surface hardness and lubricity
• Internal UN thread form at 16 TPI to ANSI B1.1:74
• R25I insert style for compatibility with matching thread mill bodies
• Manufacturer grade VBX for consistent dimensional accuracy insert-to-insert

Compatibility

Designed as an OEM-style replacement insert for R25I-style thread mill toolholders used in internal UN thread milling applications at 16 TPI.

Installation Notes

Thread mill inserts are seated and secured by a qualified machinist or toolroom technician following the toolholder manufacturer torque and seating procedures. Confirm the spindle is fully stopped and the machine is in a safe state before changing inserts. Verify insert orientation and seating before resuming cutting operations. Handle carbide inserts with care to avoid chipping the cutting edges prior to use.
