Iscar 5569352 CNMG431-M3M IC807 Carbide Turning Insert

Product Description

The ISCAR 5569352 is a solid carbide turning insert in the CNMG431-M3M geometry, designed for precision external and internal turning operations on CNC lathes and turning centers. It carries the IC807 manufacturer grade with a TiAlN and TiN PVD coating applied through ISCAR's SumoTec proprietary process, which promotes wear resistance and extended tool life across a range of workpiece materials. The insert features an 80-degree diamond shape, a positive rake angle, and an M3M chip breaker geometry. Key dimensions include a 12.9 mm insert length, a 12.7 mm inscribed circle, and a 4.76 mm thickness, with a 0.4 mm corner radius suited for medium finishing and semi-finishing passes.

This insert is part of the Isoturn series and is intended for right-hand turning applications. It is rated for use on workpiece material groups H, K, M, P, and S, covering hardened materials, cast iron, stainless steel, steel, and heat-resistant superalloys. The M3M chip breaker geometry handles moderate feed rates and depths of cut up to 4.0 mm, making it appropriate for medium-duty turning on both horizontal and slant-bed CNC turning platforms in production machining environments. Machinists and toolroom technicians in job shops, aerospace, and general manufacturing are the primary users.

Key Features

• IC807 grade with TiAlN and TiN PVD SumoTec coating for extended wear resistance
• 80-degree diamond insert shape with positive rake angle for efficient chip formation
• M3M chip breaker supports semi-finishing and medium turning operations
• Maximum depth of cut of 4.0 mm suitable for moderate material removal
• Right-hand insert orientation with CNMG-style seating for standard toolholders
• Compatible with ISO 13399 tooling data standards for CAM and tool management systems

Compatibility

Designed as an OEM-style replacement or direct-fit insert for CNMG 431 toolholder seats conforming to ISO turning insert standards. The Iso Code designation is CNMG 431-M3M per the supplier specification. No specific compatible toolholder model numbers were provided in the product data.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the machine spindle fully stopped and all axis motion disabled. Use the appropriate torx or clamp screw driver specified for the toolholder to seat the insert securely without overtightening, which can fracture the carbide substrate. Verify insert orientation and hand designation match the toolholder before engaging the first cut. Inspect the insert seat and clamp for chips or debris before loading a new insert.
