Vargus 80726 Carbide Thread Mill Insert 8 Tpi Un

Product Description

The VARGUS 80726 is a carbide thread mill insert designed for internal UN thread milling applications at 8 teeth per inch (TPI). Built from micrograin carbide and finished with a TiAlN coating applied via PVD process, this insert is engineered for cutting precision unified national threads in demanding machining environments. The VTX manufacturer grade designation indicates a high-performance tool specification suited to production threading operations. Machinists and tool-room professionals install this insert into compatible thread mill bodies to produce accurate internal threads in a range of workpiece materials.

This insert is used in CNC machining centers and manual milling operations where internal UN threads must be produced with consistent form and finish. The 8 TPI configuration makes it appropriate for coarser unified thread profiles used in general industrial fastener applications. The TiAlN PVD coating improves heat resistance and tool life when threading ferrous and hardened materials. It is typically installed by machinists, toolroom technicians, and precision manufacturing professionals working with thread milling tooling systems.

Key Features

• Micrograin carbide substrate for wear resistance and edge retention
• TiAlN coating via PVD process for improved heat resistance and extended tool life
• 8 TPI configuration for coarse unified national thread profiles
• Designed for internal thread milling applications
• Insert style R40I for use with compatible thread mill bodies
• VTX manufacturer grade for high-performance cutting applications

Compatibility

Designed for use with compatible R40I-style thread mill bodies configured for internal UN thread milling at 8 TPI. Verify insert style and thread mill body compatibility before installation.

Installation Notes

This insert is installed by qualified machinists or toolroom technicians into a compatible thread mill insert body. Power down and lock out the machine before changing inserts. Use the appropriate torx or insert-clamping tool specified by the thread mill body manufacturer to seat the insert securely. Handle carbide inserts with care to avoid chipping the cutting edge prior to use.
