Iscar 5902163 Threading Insert 5 Tpi Stub Acme IC908

Product Description

The ISCAR 5902163 is a solid carbide laydown threading insert designed for external Stub Acme thread forms at 5 threads per inch (TPI). Manufactured in the 22ER insert style with a size code of 22, it carries the IC908 grade with a TiAlN coating applied via PVD process. The inscribed circle measures 1/2 inch (0.5000 inches) and the insert thickness is 0.188 inches. This insert is configured for right-hand cutting and fits within the ISCARTHREAD series. It is installed by machinists and toolroom technicians performing precision threading operations on CNC lathes and turning centers.

This insert is suited for external Stub Acme threading applications across a wide range of workpiece materials. The IC908 grade with PVD TiAlN coating supports use on universal workpiece material groups, covering material codes H, K, M, N, P, and S. Stub Acme thread profiles are commonly found in lead screws, power transmission components, and mechanical actuator assemblies. This insert is appropriate for both production and maintenance machining environments where controlled thread form accuracy is required.
