Iscar 5902231 Threading Insert 8 Tpi Acme Solid Carbide IC908

Product Description

The ISCAR 5902231 is a laydown-style external threading insert designed for cutting Acme thread forms at 8 threads per inch (TPI). Built from solid carbide and finished with a TiAlN coating applied via PVD process, this insert delivers wear resistance and thermal stability across a wide range of workpiece materials. It carries ISCAR grade IC908 and fits the 16ER insert style. The inscribed circle measures 3/8 inch (0.375 decimal inch) and the insert thickness is 0.143 inches. Right-hand cutting geometry is configured for external Acme thread applications. Installation and setup follow ISO 13399 standard tool data conventions.

This insert is suited for external Acme thread turning operations on CNC lathes and manual turning centers. The Acme thread form is commonly machined on lead screws, power transmission components, and linear actuator shafts in industrial, tooling, and maintenance environments. The IC908 grade and TiAlN PVD coating make it compatible with a broad range of primary workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, high-temperature alloys, and hardened materials. It is sold individually (package quantity of 1) with a minimum order quantity of 5 units.
