Iscar 5901562 Threading Insert 1.25mm Iso IC908 Carbide

Product Description

The ISCAR 5901562 is a solid carbide laydown threading insert engineered for external ISO threading operations on CNC lathes and turning centers. Carrying the IC908 grade, this insert uses a PVD-applied TiAlN coating that extends tool life across a wide range of workpiece materials. It conforms to the 16ERM insert style and is designed for right-hand cutting. The inscribed circle measures 3/8 inches (0.375 inches) and the insert thickness is 0.143 inches. A corner radius of 0.0055 inches supports clean thread form at a 1.25mm pitch. The M chipbreaker geometry helps control chip flow during threading passes. Installation and use are typical for machining professionals and CNC toolroom technicians.

This insert is suited for external ISO metric threading on a broad range of materials. The IC908 grade with PVD coating targets universal workpiece material compatibility, covering material codes H, K, M, N, P, and S. Typical applications include threading steel, stainless, cast iron, non-ferrous alloys, and high-temperature alloys in production turning environments. The 16ERM geometry fits standard ISCAR THREAD toolholders designed for the 16ER insert family. It is sold individually but carries a minimum order quantity of 5 units.

Installation Notes

This insert is installed by qualified CNC machinists or toolroom technicians. Power down and lock out the machine spindle before seating or replacing inserts. Use the correct torx or hex key specified by the toolholder manufacturer to secure the insert clamp — do not overtighten by hand estimate. Confirm insert seating and thread pitch setup with a test pass before running full production.
