Vargus 65031 Carbide Thread Mill Insert 16 Tpi Un

Product Description

The VARGUS 65031 is a carbide thread mill insert engineered for internal UN thread milling operations. Manufactured from micrograin carbide and finished with a PVD TiAlN coating, this insert delivers consistent thread geometry at 16 teeth per inch on a 5/8-inch inscribed circle. The VBX grade designation indicates a wear-resistant substrate suited to demanding cutting conditions. Machinists and CNC operators working in job shops or production environments use this insert when thread milling internal UN threads in steel workpieces. It belongs to the Standard TM series and follows ANSI B1.1:74 thread standards.

This insert is designed for internal UN thread milling applications primarily in steel. The Standard TM series configuration makes it a direct-fit replacement for compatible VARGUS thread mill bodies accepting the 5I insert style with a 5/8-inch inscribed circle. Applications include CNC machining centers performing helical thread interpolation on steel parts where a PVD-coated micrograin carbide insert is specified. The P-grade workpiece material classification confirms suitability for steel cutting across a range of hardnesses.

Key Features

• Micrograin carbide substrate for improved edge stability and wear resistance
• PVD TiAlN coating reduces heat buildup and extends tool life in steel
• 16 TPI configuration for internal UN threads per ANSI B1.1:74
• 5/8-inch inscribed circle accommodates Standard TM series tool bodies
• 5I insert style designation for positive identification and correct seating
• P-grade classification - optimized for steel workpiece materials

Compatibility

Designed for use with VARGUS Standard TM series thread mill bodies that accept the 5I insert style with a 5/8-inch inscribed circle for internal UN threading applications.

Installation Notes

Installation of thread mill inserts is performed by CNC machinists and tooling technicians. Always power down and lock out the machine spindle before seating or removing inserts. Ensure the insert pocket is clean and free of chips before installation, and verify the insert is fully seated and properly torqued per the tool body manufacturer specification. Thread mill programs should be validated with a dry run before cutting to confirm correct helical interpolation direction and depth for internal threads.
