Iscar 5509910 CNMG431TF IC6025 Turning Insert Carbide

Product Description

The ISCAR 5509910 is a CNMG431TF turning insert in the Isoturn series, manufactured from solid carbide with a CVD-applied multilayer coating of TiCN, Al2O3, and TiN. The 80-degree diamond insert shape (Shape Code C) provides a strong cutting edge suited to continuous and semi-interrupted turning operations. It carries a 0.5-inch inscribed circle, a 1/64-inch (0.0156-inch) corner radius, and an insert length of 12.9 mm (0.508 inches). The IC6025 grade is engineered primarily for machining stainless steel and is held via clamp or pin in compatible CNMG-style toolholders. Installed by machinists and CNC setup technicians in production turning environments.

This insert is intended for turning stainless steel workpieces in CNC lathe and manual turning applications where wear resistance and edge stability are critical. The TF chip breaker geometry promotes positive rake cutting action and effective chip control at moderate to high feed rates. The insert thickness is 3/16 inch (0.1875 inches), and the maximum recommended depth of cut is 4.00 mm (0.1575 inches). It fits standard CNMG 431 toolholders with clamp or pin retention systems. Tolerance code M and clearance code N (0-degree relief angle) apply to this insert, consistent with ISO 13399 standards.

Key Features

• IC6025 solid carbide grade with CVD-applied TiCN, Al2O3, and TiN multilayer coating for extended tool life on stainless steel
• 80-degree diamond insert shape (CNMG) delivers strong cutting geometry for turning operations
• TF chip breaker geometry with positive rake for effective chip control
• 1/64-inch corner radius suited for general-purpose finishing and semi-finishing passes
• Maximum depth of cut of 4.00 mm (0.1575 inches) for controlled material removal
• Compatible with clamp and pin insert holding methods in standard CNMG toolholders

Compatibility

Designed for use in CNMG 431-style toolholders using clamp or pin retention. Primary workpiece material is stainless steel (ISO material code M). Conforms to ISO 13399 insert standards.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the toolholder is secured before seating or replacing the insert. Inspect the insert pocket and clamping components for wear or debris prior to installation. Do not exceed the rated maximum depth of cut for this insert geometry.
