Iscar 5507756 Turning Insert CNMG432GN IC8150 Carbide

Product Description

The ISCAR 5507756 is a solid carbide turning insert in the CNMG 432-GN geometry, part of the Isoturn series. It features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN for wear resistance and thermal stability during interrupted and continuous turning operations. The 80-degree diamond (C) insert shape provides two cutting edges per face. With a 0.5-inch inscribed circle and a 1/32-inch corner radius, this insert suits medium turning and boring passes in production environments. It is installed by CNC machinists and turning center operators working in job shops, production facilities, and tool rooms.

This insert is designed for turning and boring applications on cast iron and steel workpieces, corresponding to ISO material groups K and P. The GN chip breaker geometry is suited for general-purpose medium cutting conditions. The insert is held by clamp and pin methods, making it compatible with standard CNMG-style toolholders used on CNC lathes and turning centers in both light and medium-duty material removal applications. Maximum depth of cut is 4.5 mm (0.177 inches).

Key Features

• CVD multilayer coating: TiCN, Al2O3, and TiN for heat and wear resistance

• 80-degree diamond shape (CNMG) delivers strong cutting edge geometry
• GN chip breaker designed for general-purpose medium turning and boring
• Clamp and pin holding method for secure seating in standard CNMG toolholders
• Conforms to ISO 13399 for consistent tool data exchange

Compatibility

Designed for use in standard CNMG-style toolholders that accept clamp and pin insert retention. Suitable for CNC lathe and turning center applications targeting cast iron (ISO K) and steel (ISO P) workpieces. Compatible with boring operations per multi-use application designation. ISO code CNMG 432-GN.

Installation Notes

CNC machinists and tooling technicians should power down and lock out the turning center before seating or indexing inserts. Verify the toolholder pocket and seating surfaces are clean and free of chips before installing. Use the correct torque driver for the clamp screw as specified by the toolholder manufacturer — do not overtighten. Confirm insert seating and edge orientation before resuming spindle operation.
