Iscar 5596453 CCGT431AS IC520 Turning Insert 1/2 in Ic

Product Description

The ISCAR 5596453 is a solid carbide turning insert designed for precision external and internal turning operations on CNC lathes and turning centers. Manufactured to the CCGT431AS geometry in grade IC520, this insert features a PVD-applied TiCN and TiN coating that improves surface finish and extends tool life in demanding cutting conditions. The 80-degree diamond shape provides a strong cutting edge with positive rake geometry, while the AS chip breaker promotes reliable chip control at moderate feed rates and depths. At 12.9 mm in length with a 0.5-inch inscribed circle and a 1/64-inch corner radius, it delivers consistent geometry for tight-tolerance finish turning.

This insert is suited for finish and semi-finish turning of stainless steels, non-ferrous metals, and high-temperature alloys, corresponding to ISO material groups M, N, and S. It belongs to ISCAR's Isoturn series and is intended for use in screw-clamped toolholders that accept CCGT-style inserts. Typical applications include precision turning on production and job-shop lathes where surface integrity and dimensional accuracy are critical. It is installed by machinists, toolroom technicians, and CNC operators working in metalcutting environments.

Key Features

• IC520 grade with PVD TiCN and TiN coating for wear resistance and edge stability
• CCGT431AS geometry with positive rake and AS chip breaker for controlled chip evacuation
• 80-degree diamond insert shape (C) provides strong cutting edge geometry
• 1/64-inch (0.0156 inch) corner radius suited for fine-finish turning operations
• Maximum depth of cut of 2.50 mm (0.0984 inch) for finish-pass applications
• Meets ISO 13399 tooling data standards for compatibility with CAM and tool management systems

Compatibility

Designed as a screw-clamped replacement insert for CCGT-style toolholders accepting a 0.5-inch inscribed circle, 3/16-inch thick diamond insert. Compatible with ISO material groups M (stainless steel), N (non-ferrous), and S (high-temperature alloys) as defined in the input data.

Installation Notes

Installation is performed by qualified machinists or CNC toolroom personnel. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torx or hex key to the toolholder manufacturer's specified procedure when seating the screw clamp — avoid overtightening, which can crack the insert body. Verify seating and runout before resuming cutting operations.
