Vargus 65116 Carbide Thread Mill Insert 12 Tpi Un

Product Description

The VARGUS 65116 is a carbide thread mill insert designed for internal UN thread milling operations at 12 threads per inch. Manufactured from solid carbide in the VTX grade, this insert features a TiAlN finish applied via PVD coating, which improves heat resistance and extends tool life in demanding cutting conditions. The 5I insert style is engineered for use in thread milling applications on CNC machining centers where precise, single-point thread generation is required. It is installed and replaced by machinists and tooling specialists working with threaded bore features in ferrous and similar workpiece materials.

This insert is suited for internal UN thread milling on ferrous workpiece materials, classified under primary workpiece material code P. The 12 TPI specification targets coarse UN thread profiles conforming to ANSI B1.1:74, making it applicable to standard inch-series threaded bores found in general machining, manufacturing, and maintenance environments. It is typically used in horizontal or vertical CNC machining centers with appropriate thread mill bodies that accept the 5I insert style and size code 5.

Key Features

• Carbide substrate in VTX manufacturer grade for rigidity and wear resistance
• TiAlN PVD coating improves thermal stability and tool life at elevated cutting speeds
• 12 TPI internal thread profile conforms to ANSI B1.1:74 UN thread standard
• 5I insert style with size code 5 for indexed replacement in compatible thread mill bodies
• Designed for P-category workpiece materials including carbon and alloy steels

Compatibility

Designed as an OEM-style replacement insert for thread mill bodies that accept the 5I insert style, size code 5. Specific body compatibility should be confirmed against the toolholder manufacturer specifications before ordering.

Installation Notes

Thread mill inserts are installed and indexed by machinists using the appropriate torx or hex key specified by the toolholder manufacturer. Always power down and lock out the spindle before replacing inserts. Verify insert seating and clamp torque per the toolholder manual before resuming cutting operations. Incorrect seating or over-torquing the clamp screw can lead to insert breakage or poor thread accuracy.
