Vargus 64686 Carbide Thread Mill Insert 12 Tpi Un

Product Description

The VARGUS 64686 is a VTX-grade carbide thread mill insert designed for internal thread milling operations on UN unified thread forms. Running at 12 threads per inch (TPI), this insert carries a TiAlN (titanium aluminum nitride) coating that improves heat resistance and extends tool life in demanding cutting environments. Style designation 5I places it in a standardized insert family with consistent geometry for repeatable thread quality. Machining professionals and tool-room technicians install this insert into compatible thread mill bodies for precision internal threading on CNC machining centers.

This insert is suited for internal UN thread milling at 12 TPI in accordance with ANSI B1.1:74. The non-conical geometry and insert size code 5 make it appropriate for machining centers running standard unified thread programs. The primary workpiece material code N indicates suitability for non-ferrous and similar material groups. Typical applications include production threading of through-holes and blind holes where a milling approach is preferred over tapping, particularly in fixtures and components requiring close thread tolerances.

Key Features

• VTX carbide grade for wear resistance in thread milling operations
• TiAlN coating provides elevated heat resistance and extended tool life
• 12 TPI cutting geometry for UN internal thread forms per ANSI B1.1:74
• Insert style 5I with non-conical profile for consistent thread geometry
• Lightweight at 0.1 pounds, minimizing tool assembly imbalance

Compatibility

Designed as an OEM-style replacement insert for compatible VARGUS thread mill bodies accepting style 5I inserts. Consult the VARGUS insert-to-holder reference to confirm body compatibility before ordering.

Installation Notes

Thread mill inserts are installed and replaced by machinists or toolroom technicians on CNC machining equipment. Power down and lock out the spindle before changing inserts. Use the appropriate torque wrench and insert screw driver specified by the tool body manufacturer - do not overtighten the clamping screw. Verify insert seating and runout before returning the tool to service, and confirm programmed thread parameters match the 12 TPI specification.
