Iscar 5507802 CNMG432GN IC8250 Turning Insert 1/2 Inch Ic

Product Description

The ISCAR 5507802 is a solid carbide turning insert in the CNMG432GN geometry, designed for external and internal turning operations on CNC lathes and turning centers. Manufactured to the IC8250 grade, it features a CVD-applied TiCN and Al2O3 multilayer coating that provides wear resistance and thermal stability during continuous and interrupted cuts. The 80-degree diamond insert shape delivers a strong cutting edge with good approach angle flexibility. With an inscribed circle of 0.5 inches and an insert length of 12.9 mm (0.5079 inches), this insert is sized for medium to heavy turning passes. It is installed by machinists and CNC operators in production and job-shop environments.

This insert is suited for turning ferrous metals, with a primary workpiece material classification of P (steel) and secondary classification of M (stainless steel), following ISO material codes. It belongs to the Isoturn series and is intended for use in compatible CNMG-style toolholders with clamp and pin holding methods. Typical applications include roughing to semi-finishing passes on steel and stainless steel workpieces in both high-volume production and precision turning scenarios.

Key Features

• IC8250 grade solid carbide substrate with CVD-applied TiCN and Al2O3 multilayer coating for extended tool life
• CNMG432GN geometry with GN chip breaker for controlled chip evacuation during steel and stainless turning
• 80-degree diamond insert shape (Shape Code C) with 0 degrees relief angle (Clearance Code N)
• Corner radius of 1/32 inch (0.0315 inches) for a balance of edge strength and surface finish
• Maximum depth of cut of 4.50 mm (0.1772 inches) suitable for medium to heavy material removal
• Conforms to ISO 13399 tooling data standards for compatibility with digital tooling management systems

Compatibility

Designed for use in CNMG-style toolholders that accept clamp and pin insert holding methods. Compatible with toolholders conforming to the CNMG 432 insert seat geometry. Verify toolholder clearance angle and pocket geometry before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Use the appropriate torque wrench for the clamping screw to avoid cracking the carbide insert or damaging the toolholder seat. Inspect the insert pocket and shim for debris or wear before seating a new insert.
