Iscar 5901996 Threading Insert 10 Tpi 3/8 in IC908

Product Description

The ISCAR 5901996 is a laydown-style indexable threading insert designed for external UN thread cutting at 10 threads per inch (TPI). Manufactured from solid carbide with an IC908 grade designation and a PVD-applied TiAlN coating, this insert is engineered for consistent thread form and wear resistance across a range of workpiece materials. The right-hand cutting geometry suits standard external threading operations on CNC lathes and turning centers. The 3/8-inch (0.375-inch decimal) inscribed circle and 0.143-inch thickness conform to the 16ER insert style standard under ISO 13399.

This insert is suited for external UN threading operations in production machining environments. The IC908 grade with PVD coating performs across a broad material range, including steels, stainless steels, cast irons, aluminum alloys, and high-temperature alloys, as indicated by the material grade codes C1, C2, C6, and C7, and workpiece material codes H, K, M, N, P, and S. Typical applications include threading on turned components in job shop and production settings where consistent pitch accuracy at 10 TPI is required.

Compatibility

Designed for use in toolholders accepting the 16ER insert style as defined under the ISO 13399 standard and the ISCARTHREAD series. Confirm holder pocket geometry and insert retention method before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Shut down the spindle and engage the machine lock before indexing or replacing the insert. Use the correct torque wrench and manufacturer-specified clamp screw to seat the insert fully in the pocket - improper seating will cause thread form deviation. Inspect the insert pocket and clamp for wear or debris before installing a new insert.
