Iscar 5902012 Threading Insert 56 Tpi Un IC908 Carbide

Product Description

The ISCAR 5902012 is a solid carbide laydown threading insert designed for external UN thread cutting at 56 threads per inch. It carries the IC908 manufacturer grade, a submicron carbide substrate with a PVD-applied TiN/TiAlN coating that supports high cutting speeds and extended tool life across a broad range of workpiece materials. The insert is configured for right-hand external threading and features an inscribed circle of 9.53 mm (0.375 inches) and a thickness of 0.143 inches. It belongs to ISCARs ISCARTHREAD series and is installed by machinists and CNC tooling specialists working on threading operations in turning centers and lathes.

This insert is suited for external UN thread applications requiring 56 TPI in production turning environments. The IC908 grade with PVD coating makes it compatible with a wide range of workpiece materials including steels, stainless steels, cast irons, non-ferrous metals, and high-temperature alloys as indicated by material codes H, K, M, N, P, and S. It is appropriate for both high-volume production runs and precision threading tasks where consistent thread form and surface finish are required.

Key Features

• IC908 submicron solid carbide grade with PVD TiN/TiAlN coating for wear resistance and thermal stability
• 56 TPI for UN external thread form, right-hand cutting orientation
• 9.53 mm inscribed circle (3/8 inch) with 0.05 mm corner radius for accurate thread profile
• Chipbreaker style B for controlled chip evacuation during threading passes
• Compatible with universal workpiece material classes: H, K, M, N, P, S
• Conforms to ISO 13399 tooling data standards for integration with CAM and tooling management systems

Compatibility

Designed as an OEM-style replacement threading insert for ISCARTHREAD series toolholders accepting 16ER style laydown inserts. Specific toolholder compatibility should be verified against ISCAR toolholder documentation for the 16ER insert style.

Installation Notes

Threading inserts of this type are installed and replaced by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the appropriate torx or clamp screw driver as specified by the toolholder manufacturer to seat the insert fully and evenly without overtightening. Verify insert orientation and thread hand before resuming cuts.
