Iscar 5507622 CNMG431PP IC9350 Turning Insert Isoturn

Product Description

The ISCAR 5507622 is a solid carbide turning insert in the CNMG431PP geometry, designed for precision external turning operations on CNC lathes and turning centers. It carries the IC9350 manufacturer grade with a CVD-applied TiCN/Al2O3/TiN multilayer coating that provides thermal resistance and wear protection during interrupted and continuous cuts. The insert measures 12.9 mm (0.508 inches) in length with a 0.5-inch inscribed circle, a 3/16-inch (0.1875-inch) thickness, and a 1/64-inch (0.0156-inch) corner radius. The 80-degree diamond shape (CNMG insert style) and positive rake geometry make this insert well suited for finishing and semi-finishing passes. It is installed and replaced by machinists and CNC operators on turning toolholders that accept CNMG-style inserts.

This insert is primarily intended for machining stainless steel and carbon or alloy steel workpieces, corresponding to ISO material groups M and P. The Isoturn series designation indicates it is engineered for general turning applications where consistent surface finish and tool life are critical. It fits standard CNMG431 toolholders that use a clamp and pin holding method, making it a common choice in production turning cells handling stainless and steel components. Maximum depth of cut is 4.00 mm (0.1575 inches), which positions this insert for light to medium-duty material removal.

Key Features

• IC9350 grade with CVD TiCN/Al2O3/TiN multilayer coating for heat and wear resistance
• 80-degree diamond (CNMG) insert shape with positive rake for reduced cutting forces
• 1/64-inch corner radius suited for finishing and semi-finishing passes
• Optimized for stainless steel (ISO M) and steel (ISO P) workpiece materials
• PP chip breaker geometry for effective chip control in turning operations
• Compliant with ISO 13399 cutting tool data representation standards

Compatibility

Designed as an OEM-style replacement insert for standard CNMG431 turning toolholders that use a clamp and pin holding method. Specific toolholder compatibility should be verified against the holder manufacturer's insert geometry requirements before installation.

Installation Notes

Turning inserts of this type are installed and replaced by qualified machinists or CNC operators. Power down and lock out the machine spindle before changing inserts. Ensure the toolholder seat and clamping pocket are clean and free of chips before seating the insert, as debris under the insert will cause premature edge failure or dimensional error. Torque the clamp screw only to the toolholder manufacturer's specified value — do not over-tighten.
