Iscar 5569387 DNMG432-M3P Carbide Turning Insert IC807

Product Description

The ISCAR 5569387 is a DNMG432-M3P carbide turning insert designed for precision metal cutting on CNC lathes and turning centers. It carries the IC807 manufacturer grade and features a PVD-applied TiAlN and TiN dual coating marketed under ISCAR's SumoTec designation, which provides wear resistance and thermal stability across a range of workpiece materials. The insert measures 15.5 mm in length, 12.7 mm inscribed circle, and 4.76 mm in thickness, with a 0.8 mm corner radius. Right-hand cutting geometry and a positive rake angle make it well suited for finishing and medium turning operations. It belongs to the ISCAR Isoturn series and conforms to ISO 13399 standards.

This insert is used in turning applications across multiple workpiece material groups, including carbon and alloy steels (P), stainless steels (M), cast irons (K), hardened materials (H), and superalloys and titanium (S). The M3P chip breaker geometry is optimized to control chip formation across these material categories during external and internal turning. It fits standard DNMG-style toolholders and is a practical choice for production shops running varied material types on the same tooling setup. Maximum depth of cut is 6.00 mm.

Key Features

• IC807 carbide grade with PVD TiAlN and TiN SumoTec coating for wear and heat resistance
• 55-degree diamond insert shape (DNMG) with positive rake for reduced cutting forces
• M3P chip breaker designed for multi-material chip control
• 0.8 mm corner radius suits medium to finishing turning passes
• Maximum depth of cut: 6.00 mm
• Conforms to ISO 13399 insert identification standards

Compatibility

Compatible with standard DNMG-style turning toolholders. Rated for primary workpiece material codes H, K, M, P, and S, covering hardened materials, cast iron, stainless steel, carbon and alloy steels, and superalloys. Part of the ISCAR Isoturn series.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and clamping screw to seat the insert fully and evenly in the toolholder pocket. Do not use damaged or chipped inserts, as they compromise surface finish and tool life.
