Iscar 5509376 Turning Insert CNMX452M4MW IC6015 Heliturn

Product Description

The ISCAR 5509376 is a CNMX-style solid carbide turning insert in the Heliturn series, grade IC6015, designed for high-performance external turning operations on CNC lathes and turning centers. The insert features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, which provides wear resistance and thermal stability across a range of cutting conditions. With an 80-degree diamond shape, a 0.5-inch inscribed circle, and a corner radius of 0.03125 inches, this insert delivers controlled chip formation through its MMW chip breaker geometry. It is suited for machining ISO material group M workpieces and is installed by machinists and toolroom technicians in production and job-shop environments.

This insert is rated for a maximum depth of cut of 6.00 mm (0.2362 inches) and accommodates both clamp and pin holding methods, making it compatible with standard CNMX insert pockets. The Heliturn series is intended for medium turning applications where chip control and edge stability are priorities. The wiper edge geometry improves surface finish at higher feed rates without requiring a reduction in cutting speed. The positive rake design reduces cutting forces, which is beneficial when machining stainless steels and other difficult-to-cut ISO M-group materials.

Key Features

• CVD multilayer coating: TiCN, Al2O3, TiN for wear and thermal resistance
• MMW chip breaker geometry with wiper edge for improved surface finish
• 80-degree diamond insert shape with positive rake for reduced cutting forces
• Compatible with clamp and pin insert holding methods
• Maximum depth of cut: 6.00 mm (0.2362 inches)
• Meets ISO 13399 standards for tool data representation

Compatibility

Designed as an OEM-style replacement or direct-use insert for CNMX-style insert pockets in Heliturn series toolholders accepting size 452 inserts with clamp and pin holding. Specific toolholder compatibility should be confirmed against ISCAR Heliturn system specifications.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Power down and lock out the machine before seating or replacing inserts. Use the appropriate torx or insert-clamping key specified for the toolholder; do not overtighten the clamp screw. Inspect the insert pocket and seating surfaces for debris or damage before installing a new insert.
