Iscar 5507843 Cnmg 431-GN IC8150 Turning Insert Carbide

Product Description

The ISCAR 5507843 is a CNMG 431-GN IC8150 grade turning insert designed for precision metal cutting in CNC and manual lathe applications. It features a multilayer CVD coating of TiCN, Al2O3, and TiN applied over a solid carbide substrate, providing wear resistance and thermal stability at the cutting edge. The insert has an 80-degree diamond shape, a 0.5 inch inscribed circle, a corner radius of 0.016 inches (1/64 inch), and an insert length of 12.90 mm (0.508 inches). Insert thickness is 0.187 inches (3/16 inch). This insert belongs to the Isoturn series and is suitable for medium to finish turning operations. It is installed and indexed by licensed machinists and CNC operators.

This insert is suited for turning cast iron and steel workpieces in both roughing and finishing passes where a durable CVD-coated carbide grade is required. The GN chip breaker geometry supports controlled chip formation across a range of depths of cut up to 3.99 mm (0.157 inches). It is appropriate for production environments running steel and cast iron components where consistent tool life and surface finish are priorities. The CNMG form factor fits standard CNMG-style toolholders using clamp or pin holding methods.

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for extended wear resistance
• IC8150 grade carbide substrate engineered for steel and cast iron cutting
• 80-degree diamond insert shape (ISO shape code C) for versatile turning profiles
• GN chip breaker for controlled chip evacuation during medium turning
• Maximum depth of cut: 3.99 mm (0.157 inches)
• Conforms to ISO 13399 tooling data standards

Compatibility

Designed for use in standard CNMG-style turning toolholders that accept clamp or pin holding methods. Primary workpiece materials are cast iron (ISO material code K) and steel (ISO material code P). Part of the ISCAR Isoturn series.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Shut down the machine and engage all lockout-tagout procedures before indexing or replacing inserts. Use the appropriate torque wrench and insert key for the toolholder clamp screw to avoid cracking the carbide. Inspect the toolholder pocket and seating surfaces for debris or wear before seating the new insert.
