Ingersoll Cutting Tools 5523178 Turning Insert CNMG432EM

Product Description

The INGERSOLL CUTTING TOOLS 5523178 is a CNMG-style solid carbide turning insert designed for precision metal removal on CNC lathes and turning centers. Coated with AlTiN and TiN via a PVD process, this insert delivers heat resistance and extended tool life in demanding cutting environments. It features an 80-degree diamond insert shape, a neutral hand orientation, and an EM chip breaker geometry. The inscribed circle measures 0.5000 inches with a corner radius of 0.0310 inches and an insert length of 0.5080 inches. Installation is performed by qualified machinists and CNC operators working with indexable toolholders.

This insert is rated for primary use on stainless steel, super-alloys, and titanium workpiece materials, making it well suited for aerospace, medical, and energy sector turning applications. The negative rake geometry and four cutting edges support productive roughing and semi-finishing passes. With a maximum depth of cut of 0.2000 inches and a clamp-style holding method, it fits standard CNMG-format toolholders. The ISO designation is CNMG120408EM TT5080 and the ANSI code is CNMG432EMTT5080, supporting cross-reference sourcing across tooling systems.

Key Features

• Solid carbide substrate with AlTiN and TiN PVD coating for elevated heat and wear resistance
• 80-degree diamond insert shape with neutral hand orientation for versatile turning setups
• EM chip breaker geometry optimized for stainless steel, super-alloys, and titanium
• Four cutting edges per insert for maximum index life from each piece
• Corner radius of 0.0310 inches supports controlled surface finish in finishing passes
• Maximum depth of cut of 0.2000 inches suitable for semi-finishing and moderate roughing

Compatibility

Designed for use in standard CNMG-format indexable turning toolholders accepting a 1/2-inch inscribed circle insert with clamp-style holding. ISO code CNMG120408EM TT5080 and ANSI code CNMG432EMTT5080 apply for toolholder cross-reference. Primary workpiece material codes M and S indicate suitability for stainless steel and super-alloys including titanium.

Installation Notes

Installation is performed by machinists or CNC tooling technicians using the appropriate CNMG clamp-style toolholder and insert seating torque specified by the toolholder manufacturer. Ensure the machine spindle is fully stopped and the turret is in a safe index position before handling or indexing inserts. Inspect the insert pocket and clamp for wear or debris before seating a new insert. Follow the cutting tool manufacturer recommendations for speeds, feeds, and coolant strategy when machining stainless steel or titanium alloys.
