Vargus 64968 Carbide Thread Mill Insert 28 Tpi Un

Product Description

The VARGUS 64968 is a carbide thread mill insert designed for external UN thread milling applications at 28 teeth per inch (TPI). Built from micrograin carbide in insert style 3E, it carries a TiCN coating applied via PVD process, which improves surface hardness and wear resistance during high-cycle threading operations. With a 3/8 inch (9.53 mm) inscribed circle, the insert seats in compatible thread mill bodies for precise, repeatable thread form generation. This insert is used by machinists and CNC tooling technicians in production environments where thread accuracy and tool longevity are critical.

This insert is suited for external UN thread milling on ferrous and non-ferrous workpiece materials in CNC machining centers. The 28 TPI specification targets fine-pitch thread profiles in the UN standard, making it appropriate for applications where tight thread tolerances are required. It is packaged as a single insert with a minimum order quantity of 10 units, making it a standard replenishment item for shops running ongoing thread milling operations.

Key Features

• Micrograin carbide substrate provides high hardness and edge integrity at elevated cutting speeds
• TiCN coating via PVD process improves wear resistance and reduces built-up edge
• 28 TPI external UN thread form for fine-pitch thread milling
• 3/8 inch (9.53 mm) inscribed circle for precise insert seating in compatible bodies
• Insert style 3E geometry engineered for thread mill tooling systems
• Manufacturer grade VBX for consistent dimensional and cutting performance

Compatibility

Designed as a replacement thread mill insert for VARGUS thread milling systems accepting 3E style inserts with a 3/8 inch inscribed circle. Confirm compatibility with your specific tool body before ordering.

Installation Notes

Thread mill insert replacement is performed by qualified CNC tooling technicians or machinists. Always power down and lock out the machine spindle before changing inserts. Use the appropriate torx or hex key as specified by the tool body manufacturer when seating the insert, and verify insert clamping torque meets the tool body specification. Inspect the insert pocket for wear or debris before installing a new insert to ensure proper seating and thread accuracy.
