Vargus 80499 Carbide Thread Mill Insert 14 Tpi Un

Product Description

The VARGUS 80499 is a carbide thread milling insert designed for internal UN thread forms at 14 threads per inch (TPI). Finished with a TiCN coating applied via PVD process, this insert delivers consistent thread geometry on steel and ferrous workpiece materials. Insert style is R25I with size code 25 and manufacturer grade VBX. It is intended for use in CNC machining centers with thread milling toolholders, installed by machinists and tooling specialists working to ANSI B1.1:74 thread standards.

This insert is suited for internal threading operations on ferrous materials, designated by primary workpiece material code P, which corresponds to steels. The R25I insert style is matched to compatible thread mill bodies accepting size 25 inserts. Typical applications include production threading of tapped holes where thread milling is preferred over tapping for accuracy, tool life, or interrupted-cut conditions.

Key Features

• Carbide substrate with VBX grade for wear resistance in ferrous materials
• TiCN coating via PVD process for improved surface hardness and tool life
• Internal UN thread form at 14 TPI per ANSI B1.1:74
• R25I insert style, size code 25 for precise seating in compatible bodies
• Lightweight at 0.01 pounds for easy handling and inventory management

Compatibility

Designed as an OEM-style replacement insert for thread mill bodies accepting R25I size 25 carbide inserts used in internal UN threading applications.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before changing inserts. Seat the insert fully in the toolholder pocket and torque the clamping screw per the toolholder manufacturer specification. Inspect the insert seating and clamping before resuming cutting operations.
