Iscar 5901563 Threading Insert 1.75mm Iso IC908 Carbide

Product Description

The ISCAR 5901563 is a solid carbide laydown threading insert designed for external ISO thread cutting on CNC lathes and threading machines. Built to the 16ERM insert style, it carries the IC908 manufacturer grade with a PVD-applied TiAlN coating, delivering strong wear resistance and thermal stability across a broad range of workpiece materials. The insert features a 1.75mm pitch for ISO-standard thread profiles and a right-hand cutting orientation. With a 3/8-inch (0.375-inch) inscribed circle and a thickness of 0.143 inches, it seats securely in compatible 16ERM toolholders. Machinists and CNC operators in production and job-shop environments install this insert for precision external threading passes.

This insert is suited for external ISO threading on a wide variety of metallic workpieces. The IC908 grade with PVD TiAlN coating supports use on carbon steels, stainless steels, cast irons, non-ferrous alloys, high-temperature alloys, and other materials covered under the universal primary workpiece material designation, referenced by ISO material codes H, K, M, N, P, and S. It is appropriate for both light-production and high-volume threading applications where consistent thread form and tool life are priorities. The M-style chipbreaker aids chip control during threading passes.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and insert screw specified for the toolholder to avoid insert movement or seat damage during cutting. Inspect the toolholder pocket and clamping components for wear or debris before seating the new insert.
