Iscar 5507797 CNMG432GN IC807 Turning Insert 80 Diamond

Product Description

The ISCAR 5507797 is a CNMG432GN-style indexable turning insert in the Isoturn series, manufactured from solid carbide with a PVD-applied TiAlN coating. It features an 80-degree diamond shape (Insert Shape Code C), a 0.5-inch inscribed circle, and a 1/32-inch (0.0315 inch) corner radius. Insert length is 12.9 mm (0.5079 inch) and insert thickness is 3/16 inch (0.1874 inch). The GN chip breaker geometry and IC807 grade are suited for turning operations in steel, stainless steel, and high-temperature alloys. Installation is performed by licensed machinists and CNC turning center operators.

This insert is designed for external and internal turning applications where controlled chip formation and wear resistance are priorities. The IC807 PVD TiAlN coating provides thermal stability and edge toughness at moderate-to-high cutting speeds. Primary workpiece material compatibility codes include M (stainless steel), P (steel), and S (high-temperature alloys and titanium), making it applicable across general machining and aerospace-grade turning operations. The Isoturn series is engineered for consistent insert-to-insert repeatability in production environments.

Key Features

• IC807 grade with PVD TiAlN coating for high edge integrity and thermal resistance
• 80-degree diamond insert shape (CNMG) with GN chip breaker for effective chip control
• 0.5-inch inscribed circle with 1/32-inch corner radius for versatile depth-of-cut profiles
• Maximum depth of cut: 4.50 mm (0.1772 inch)
• Clamp and pin insert holding method for secure seating in standard CNMG toolholders
• Meets ISO 13399 standard for cutting tool data representation

Compatibility

Designed as an OEM-style replacement for CNMG432 indexable turning inserts in standard CNMG-style toolholders with clamp-and-pin holding systems. Compatible with workpiece materials designated under ISO material codes M, P, and S.

Installation Notes

Installation is performed by qualified machinists following standard indexable insert procedures. Power down and lock out the machine spindle before indexing or replacing inserts. Use the appropriate torque wrench and manufacturer-specified clamping hardware to seat the insert securely — do not overtighten the clamp screw by hand estimation alone. Inspect the insert pocket and seating surface for chips or debris before installing a new insert edge.
