Vargus 80506 Carbide Thread Mill Insert 8 Tpi Un

Product Description

The VARGUS 80506 is a carbide thread mill insert designed for internal thread milling operations on UN unified thread profiles at 8 threads per inch. The insert carries a TiAlN coating applied via PVD process, which provides thermal resistance and surface hardness suited for demanding cutting applications. Designated as VBX grade carbide, this insert fits the R25I insert style in size code 25. It is installed into compatible VARGUS VTX thread mill bodies and is typically used by machinists and tooling technicians working on CNC milling centers where thread milling is preferred over tapping.

This insert is intended for internal thread milling of UN unified inch threads at 8 TPI. It is suited for use on milling machines running ISO material group M workpiece materials, which includes stainless steels and similar alloys. Thread milling with this insert type is common in precision machining environments, aerospace component shops, and general metalworking facilities where thread quality and tool life consistency are critical. Conforms to ANSI B1.1:74 threading standards.

Key Features

• VBX grade carbide substrate for hardness and wear resistance in demanding cuts
• TiAlN coating applied via PVD process for thermal protection and extended tool life
• R25I insert style, size code 25, for use in compatible VTX thread mill bodies
• Internal UN thread profile at 8 TPI conforming to ANSI B1.1:74
• Rated for ISO material group M workpiece materials including stainless steel

Compatibility

Designed as a replacement insert for compatible VARGUS VTX series thread mill bodies accepting the R25I insert style in size code 25.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the CNC machine before changing inserts. Seat the insert fully and evenly in the pocket and torque the clamping screw to the tool body manufacturer specification listed in the toolholder documentation. Inspect the insert seating and pocket condition before resuming cutting operations.
