Iscar 5569353 Cnmg 432-M3M IC807 Carbide Turning Insert

Product Description

The ISCAR 5569353 is a CNMG 432-M3M solid carbide turning insert from the Isoturn series, coated with TiAlN and TiN via a PVD process using ISCAR's SumoTec proprietary coating designation. Graded IC807, this right-hand insert features an 80-degree diamond shape (shape code C) with a positive rake geometry and M3M chip breaker. It measures 12.90 mm (0.508 inches) in length, carries an inscribed circle of 12.70 mm (0.500 inches), and has a corner radius of 0.80 mm (0.031 inches). Insert thickness is 4.76 mm (0.187 inches). Maximum depth of cut is 5.00 mm (0.197 inches). It conforms to ISO 13399 standards and carries tolerance code M with clearance code N.

This insert is suited for turning operations across a broad range of workpiece materials, including hardened steels (H), cast irons (K), stainless steels (M), carbon and alloy steels (P), and heat-resistant superalloys (S). It is used in general-purpose external and internal turning applications on CNC lathes in both production shop and maintenance environments. The M3M chip breaker geometry handles medium cutting conditions, making it a common choice for roughing to semi-finishing passes on the material groups listed. Licensed machinists and CNC operators are the primary users of this insert.

Key Features

• M3M chip breaker designed for medium-depth turning passes
• Maximum depth of cut of 5.00 mm (0.197 inches)
• Conforms to ISO 13399 tooling data standards
• Right-hand cutting orientation, tolerance code M, clearance code N

Compatibility

Designed for use in CNMG 432-compatible turning insert pockets on standard ISO toolholders accepting the CNMG insert style. Compatible with workpiece material groups H, K, M, P, and S as defined by ISO material classification.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Always power down and lock out the machine before seating or replacing inserts. Use the correct torque driver for the insert clamping screw to avoid damaging the pocket or insert seat — refer to the toolholder manufacturer's clamping specification. Inspect the insert pocket for chips or debris before seating the new insert to ensure proper contact and tool life.
