Vargus 59757 Laydown Threading Insert 24 Tpi Un Carbide

Product Description

The VARGUS 59757 is a solid carbide laydown threading insert designed for external UN thread cutting at 24 threads per inch. Manufactured in the VRX grade with a PVD-applied AlTiN coating, it is engineered for right-hand external threading operations on UN-standard thread forms. The insert features a 60-degree included angle and a 3/8-inch inscribed circle, placing it in the 3ER insert style. At 3.60 mm (0.1417 inches) thick, this laydown insert is suited for CNC lathes and threading tool holders accepting the 3ER seat geometry. Machinists, tool and die makers, and CNC operators working in precision threading applications are the primary users.

This insert is used in external threading operations where UN thread forms at 24 TPI are required. Typical applications include threading on ferrous and non-ferrous workpieces in production machining environments. The AlTiN PVD coating provides elevated hardness and heat resistance, making it suitable for dry or semi-dry cutting conditions and higher-speed threading passes. It fits standard 3ER laydown insert toolholders used in both manual and CNC turning centers.

Key Features

• Solid carbide construction in VRX manufacturer grade for consistent threading performance
• AlTiN coating applied via PVD process for improved wear resistance and heat tolerance

Compatibility

Designed as an OEM-style replacement threading insert for 3ER-style laydown insert toolholders used in external UN thread turning applications.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Power down and lock out the machine spindle before seating or replacing the insert. Ensure the insert pocket and clamping screw are clean and free of chips before seating the insert. Verify toolholder compatibility with the 3ER insert style and confirm thread pitch programming matches the 24 TPI specification before resuming cutting operations.
