Iscar 5902596 Threading Insert 11 Tpi 3/8 Inch IC908 Carbide

Product Description

The ISCAR 5902596 is a laydown-style threading insert designed for external UN thread forms at 11 threads per inch (TPI). Built from solid carbide with an IC908 grade designation and a PVD-applied TiAlN coating, this insert delivers wear resistance and thermal stability during single-point threading operations on CNC lathes and turning centers. The 16ER insert style seats in standard ER-type threading toolholders. With a 3/8 inch (0.375 inch) inscribed circle and a thickness of 0.143 inches, it fits the geometry of a wide range of ER-series cartridges. Licensed machinists and CNC operators working in job shops or production environments are the primary users.

This insert is configured for right-hand external threading to the UN thread standard. The IC908 grade with TiAlN coating is suited for universal workpiece material applications, covering a broad range of material groups including steel, stainless steel, cast iron, non-ferrous metals, high-temperature alloys, and hardened materials as indicated by the primary workpiece material codes H, K, M, N, P, and S. It is appropriate for both roughing and finishing passes on threaded features in precision machining environments.

Key Features

• 11 TPI external UN thread profile, right-hand orientation
• 3/8 inch (0.375 inch) inscribed circle in 16ER insert style for standard ER-series toolholders
• Corner radius of 0.011 inches (0.28 mm) for defined thread root geometry
• Conforms to ISO 13399 tooling data standards for digital tool management integration
• Insert thickness of 0.143 inches for stable seating in compatible toolholders

Compatibility

Designed as an OEM-style replacement threading insert for ER-series external threading toolholders accepting the 16ER insert style with a 3/8 inch inscribed circle. Verify toolholder insert pocket geometry and thread pitch before installation.

Installation Notes

Threading inserts are installed by qualified CNC machinists or toolroom technicians. Ensure the machine spindle is fully stopped and all motion is locked out before changing inserts. Use the appropriate torx or clamp screw driver to the toolholder manufacturer's specified seating procedure — do not overtighten the clamp screw. Confirm insert orientation matches the required thread hand before resuming cutting operations.
