Vargus 64475 Carbide Thread Mill Insert 12 Tpi Un

Product Description

The VARGUS 64475 is a carbide thread mill insert designed for internal UN thread milling applications. Manufactured from solid carbide with a TiAlN finish applied via PVD coating process, this insert delivers consistent thread form accuracy at 12 threads per inch. The insert style is 3I with an insert size code of 3, conforming to ANSI B1.1:74 standards. It is used in thread milling operations on CNC machining centers and is sized for production or maintenance environments where reliable UN thread geometry is required. The manufacturer grade is VTX, indicating a high-wear-resistance substrate suited for non-ferrous and general-purpose workpiece materials.

This insert is suited for internal thread milling on UN-series threads at 12 TPI. The 3I insert style fits compatible thread mill toolholders designed for that insert profile. Typical applications include threading bores in aluminum, brass, and similar non-ferrous materials, consistent with the primary workpiece material code N designation. Machinists and CNC tool setters in production shops, job shops, and maintenance facilities are the primary users of this insert type.

Key Features

• Carbide substrate with TiAlN coating for extended tool life in non-ferrous materials
• PVD coating process preserves sharp cutting edge geometry
• 12 TPI internal UN thread form per ANSI B1.1:74
• Insert style 3I, size code 3 for use in compatible thread mill bodies
• VTX manufacturer grade for consistent performance and dimensional repeatability

Compatibility

Designed as a replacement thread mill insert for VARGUS 3I-style thread mill toolholders accepting size code 3 inserts. Specific toolholder compatibility should be confirmed against the VARGUS 3I thread mill body series specifications.

Installation Notes

Thread mill inserts are installed and replaced by machinists or CNC tooling technicians. Always power down and lock out the machine spindle before changing inserts. Use the correct torx or hex key specified for the insert clamping screw to avoid stripping the seat. Handle carbide inserts carefully to prevent chipping of the cutting edges prior to use.
