Vargus 64338 Carbide Thread Mill Insert Npt 14 Tpi

Product Description

The VARGUS 64338 is a carbide thread mill insert designed for cutting NPT (National Pipe Taper) threads at 14 threads per inch (TPI). Finished with a TiCN (Titanium Carbonitride) coating applied via PVD process, this insert delivers improved wear resistance and surface hardness compared to uncoated tooling. Insert style is 3EI with size code 3 and manufacturer grade VBX. It is suited for both internal and external thread milling operations and is installed into compatible thread mill toolholders used on CNC machining centers.

This insert is used in precision thread milling applications where NPT pipe thread forms are required. The 14 TPI specification matches standard NPT pipe thread geometry per USAS B2.1:1968. Typical applications include machining pipe thread connections in ferrous and stainless workpieces. The insert is appropriate for use in job shop, production machining, and maintenance-repair environments where consistent thread form accuracy is required.

• NPT thread form at 14 TPI per USAS B2.1:1968 standard
• Capable of both internal and external thread milling in a single insert
• Insert style 3EI, grade VBX, size code 3 for straightforward replacement identification

Compatibility

Designed as an OEM-style replacement insert for compatible VARGUS TM2VTX series thread mill toolholders accepting 3EI style inserts. Confirm toolholder insert style and size code before ordering.

Installation Notes

Thread mill inserts are installed and replaced by machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the correct torque driver or insert key specified by the toolholder manufacturer to seat the insert properly. Handle carbide inserts with care to avoid chipping the cutting edges during installation.
