Vargus 59294 Laydown Threading Insert 5IR 4 Tpi Api

Product Description

The VARGUS 59294 is a solid carbide laydown threading insert designed for internal API thread cutting at 4 threads per inch (TPI). The insert carries a TiN coating applied via PVD process, which improves surface hardness and wear resistance during threading operations. It features an 5IR insert style with a 60-degree included angle and a 5/8-inch (15.88 mm) inscribed circle. Thickness is 6.35 mm. This is a right-hand insert with one tooth per side, suited for machinists and toolroom professionals working to API threading standards on internal bores.

This insert is intended for use on CNC lathes and turning centers performing internal API thread forms on pipe, coupling, and downhole component profiles. The API thread standard is common in oil and gas applications, and this insert is appropriate for production and repair threading operations in job shops, machine shops, and oilfield service environments where consistent API thread form accuracy is required. The solid carbide substrate and PVD TiN finish support reliable performance on steel and alloy materials typical in these applications.

Key Features

• Solid carbide substrate with PVD-applied TiN coating for extended wear life
• 5IR insert style for internal laydown threading applications
• 4 TPI cutting geometry conforming to API thread standard
• 60-degree included angle with right-hand cutting orientation
• 15.88 mm (5/8 inch) inscribed circle, 6.35 mm thickness
• Single tooth per side for precise API internal thread form control

Compatibility

Designed for use in laydown threading toolholders accepting 5IR-style inserts. Suitable for internal API thread turning operations on CNC lathes and turning centers. Confirm toolholder seat geometry and insert pocket dimensions before installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine before seating or replacing inserts. Use the appropriate torque wrench and insert screw to secure the insert in the toolholder pocket - do not overtighten by hand. Verify thread form with a calibrated API thread gauge after initial cuts before running production.
