Iscar 5569355 CNMG543-M3M IC807 Carbide Turning Insert

Product Description

The ISCAR 5569355 is a CNMG543-M3M indexable turning insert in grade IC807, designed for external and internal turning operations on CNC lathes and turning centers. The insert is manufactured from solid carbide and features a PVD-applied TiAlN and TiN multilayer coating with ISCARs SumoTec surface treatment, which improves edge toughness and reduces built-up edge. The diamond-shaped (C) geometry carries an 80-degree included angle, a 1.2 mm corner radius, and a positive rake configuration. It measures 16.12 mm in length with a 15.88 mm inscribed circle and a 6.35 mm thickness. Licensed machinists and CNC operators install this insert as a direct indexable tooling component.

This insert is rated for use across multiple ISO workpiece material groups: P (steel), M (stainless steel), K (cast iron), H (hardened materials), and S (superalloys and titanium). The M3M chip breaker geometry is suited for medium machining conditions where chip control and surface finish consistency are critical. The Isoturn series designation places this insert within ISCARs standard external turning platform, making it applicable to a wide range of production turning operations in both job-shop and high-volume manufacturing environments.

Key Features

• IC807 carbide grade with PVD TiAlN and TiN coating plus SumoTec surface treatment for extended tool life
• M3M chip breaker for reliable chip control in medium turning passes
• 80-degree diamond insert shape (ISO code C) with positive rake for reduced cutting forces
• 1.2 mm corner radius (0.047 inches) balances edge strength with surface finish capability
• Maximum depth of cut of 7.00 mm (0.276 inches)
• Right-hand cutting configuration; conforms to ISO 13399 tooling data standards

Compatibility

Designed as an OEM-style indexable replacement for CNMG 543 seat toolholders in the ISCAR Isoturn series. Compatible with ISO workpiece material groups H, K, M, P, and S as stated by the manufacturer.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and insert screw specified by the toolholder manufacturer — do not overtighten, as this can fracture the carbide substrate. Verify insert seating and clamp condition before resuming cutting operations.
