Vargus 53589 Threading Insert 16 Tpi Un Solid Carbide

Product Description

The VARGUS 53589 is a laydown-style threading insert designed for internal UN thread forms at 16 threads per inch. Manufactured from solid carbide with a TiAlN coating applied via PVD process, it delivers consistent thread quality across a wide range of workpiece materials. The insert follows the 3JIR style with a 60-degree included angle, a 9.53 mm inscribed circle (3/8 inch), and a 3.6 mm thickness. It is intended for use by machinists and toolroom technicians running CNC lathes or manual turning equipment where precise internal threading is required.

This insert is suited for right-hand internal threading operations on UN-standard thread forms at 16 TPI. The Universal workpiece material designation means it performs across common material categories including steel, stainless steel, cast iron, non-ferrous alloys, and high-temperature alloys. It fits standard laydown threading toolholders designed for the 3JIR insert style. Typical applications include production threading of nuts, fittings, couplings, and other internally threaded components in job shop or production environments.

Key Features

• Solid carbide substrate with TiAlN PVD coating for wear resistance across universal material groups
• 16 TPI UN internal thread form with 60-degree included angle per ANSI B1.1:74
• 3JIR laydown insert style with SCB chipbreaker geometry
• 9.53 mm inscribed circle (3/8 inch) and 3.6 mm thickness for precise toolholder seating
• Right-hand cut orientation for standard internal threading passes
• Manufactured to ISO 9001:2008 quality standards

Compatibility

Designed as an OEM-style replacement insert for 3JIR-style laydown threading toolholders accepting a 3/8-inch inscribed circle insert for internal UN thread applications.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer's seating and clamping specifications. Ensure the machine spindle is fully stopped and all motion has ceased before indexing or replacing the insert. Use the correct torque wrench per the toolholder manufacturer's recommendation when securing the clamping screw. Verify insert orientation and thread hand before beginning the threading pass.
