Iscar 5902006 Threading Insert 36 Tpi Un Solid Carbide IC908

Product Description

The ISCAR 5902006 is a laydown threading insert designed for external UN thread cutting at 36 threads per inch. Built from solid carbide with a TiAlN PVD coating in the IC908 grade, this insert delivers wear resistance and thermal stability across a broad range of workpiece materials. The 3/8 inch (0.375 inches) inscribed circle and 0.143 inch thickness conform to the 16ER insert style. Right-hand orientation and the ISCARTHREAD series geometry make it a direct-fit choice for compatible laydown threading toolholders. Machinists and CNC operators in production or job-shop environments rely on this insert for consistent thread form on external profiles.

This insert is suited for external UN threading operations on lathes and turning centers. The IC908 grade with PVD TiAlN coating is rated for universal primary workpiece material compatibility, covering ISO material groups H, K, M, N, P, and S. Typical applications include threading fastener stock, fittings, and precision components where controlled thread form and tool life consistency are required. It is sold individually but carries a minimum order quantity of 5 units.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist following the toolholder manufacturer's torque and clamping procedures. Power down and lock out the machine spindle before changing inserts. Inspect the insert pocket and clamping screw for wear or contamination before seating a new insert. Do not exceed the cutting parameters specified by ISCAR for the IC908 grade and the target workpiece material group.
