Iscar 5508202 Turning Insert 3/8 in Ic Diamond IC8150

Product Description

The ISCAR 5508202 is a CCMT-style solid carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. Manufactured to ISO 13399 standards, it features a multilayer CVD coating of TiCN, Al2O3, TiCN, and TiN for improved wear resistance and thermal stability during continuous and interrupted cuts. The 80-degree diamond shape provides two usable cutting edges, and the SM chip breaker geometry promotes effective chip control at moderate feeds and depths. This insert is installed by machinists and CNC operators performing finish to semi-finish turning operations on cast iron and steel workpieces.

The 5508202 is suited for finish and semi-finish turning of cast iron and steel components in production and job-shop environments. The positive rake geometry and SM chip breaker make it appropriate for light to moderate cuts where chip management and surface finish are priorities. With a maximum depth of cut of 0.0984 inches (2.50 mm) and a 1/64-inch corner radius, it is well matched to tight-tolerance turning passes on external diameters and facing operations. It belongs to ISCAR's Isoturn series and is held in place by a screw-type clamping method.

Key Features

• Solid carbide substrate with multilayer CVD coating: TiCN, Al2O3, TiCN, and TiN for extended tool life
• 80-degree diamond insert shape (CCMT style) with positive rake for reduced cutting forces
• SM chip breaker geometry engineered for effective chip control on steel and cast iron
• 3/8-inch inscribed circle with 1/64-inch corner radius for semi-finish to finish turning
• Screw-lock insert holding method for repeatable positioning and rigid clamping
• Conforms to ISO 13399 for direct integration with tooling data systems

Compatibility

Designed for use in CCMT-style screw-lock turning toolholders within the ISCAR Isoturn series. Primary workpiece materials are cast iron (ISO material code K) and steel (ISO material code P). Verify toolholder seat size accepts a 3/8-inch inscribed circle CCMT insert before installation.

Installation Notes

This insert is installed by qualified machinists or CNC operators. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate Torx or hex key for the clamping screw and seat the insert fully against both locating walls of the pocket before tightening. Inspect the insert seat and shim for damage each time the insert is indexed to maintain cutting geometry and prevent premature tool failure.
