Iscar 5902299 Threading Insert 8 Tpi Api Round IC908

Product Description

The ISCAR 5902299 is a solid carbide laydown threading insert engineered for external API Round thread applications. Carrying the IC908 manufacturer grade with a PVD-applied TiAlN coating, this insert delivers wear resistance and thermal stability across a broad range of workpiece materials. It is configured for right-hand cutting with a thread pitch of 8 threads per inch (TPI) and an inscribed circle of 0.375 inches. The 16ER insert style seats in compatible laydown threading toolholders and is used by machinists and CNC operators producing API Round-profile threads on pipe, couplings, and downhole components.

This insert is suited for external threading operations on oil-country tubular goods and other API Round thread profiles in both production and job-shop environments. The IC908 grade with PVD coating is rated for universal primary workpiece material compatibility, covering steel, stainless steel, cast iron, nonferrous alloys, and high-temperature alloys. It is a standard fit for ISCARTHREAD series toolholders accepting the 16ER insert style.

Key Features

• IC908 solid carbide grade with PVD TiAlN coating for extended tool life across material groups
• 8 TPI API Round external thread form for oil-country and pipe threading applications
• Right-hand cutting orientation
• 3/8 inch (0.375 inches) inscribed circle, 16ER insert style
• Corner radius of 0.0169 inches (0.43 mm) for controlled thread form accuracy
• ISO 13399 compliant tooling data for CAM and presetter integration

Compatibility

Designed as a replacement-style laydown threading insert for ISCARTHREAD series toolholders accepting the 16ER insert style. Confirm holder seat geometry and clamping method before installation.

Installation Notes

Threading inserts are installed and replaced by machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the correct torque wrench and manufacturer-specified clamping screw to seat the insert fully in the pocket. Inspect the toolholder seat for chips or wear before seating a new insert to ensure proper support and thread-form accuracy.
