Iscar 5509912 Turning Insert CNMG432TF IC6025 Carbide

Product Description

The ISCAR 5509912 is a CNMG432TF IC6025 grade solid carbide turning insert designed for use on CNC lathes and turning centers in metalworking and machining operations. The insert carries a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, delivering wear resistance and thermal protection across a range of cutting conditions. It features an 80-degree diamond shape (Insert Shape Code C), a 0.5-inch inscribed circle, a 1/32-inch corner radius, and an insert thickness of 3/16 inch. The IC6025 grade is categorized for primary workpiece material code M, indicating suitability for stainless steel and similar materials. Installation is performed by licensed machinists and CNC setup technicians.

This insert fits into the Isoturn turning insert series and is suited for external turning applications on CNC lathes and manual turning equipment that accept CNMG-style toolholders with clamp and pin holding methods. The TF chip breaker geometry supports controlled chip formation during medium-depth turning passes. The maximum depth of cut is 4.00 mm (0.1575 inches), making it appropriate for medium material removal rates. Primary workpiece material code M includes stainless steel and similar ISO M-classification alloys. Confirm toolholder compatibility with CNMG insert style and N clearance code before installation.

Installation Notes

This insert is installed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle completely before changing inserts. Use the appropriate torqx or hex key as specified by the toolholder manufacturer when securing the clamp or pin — do not overtighten. Inspect the insert pocket and seating surface for debris or damage before seating the new insert.
