Iscar 5603289 Milling Insert IC28 Solid Carbide Uncoated

Product Description

The ISCAR 5603289 is a solid carbide milling insert designed for high-efficiency face and shoulder milling operations in non-ferrous metal applications. Manufactured to the HM90 APCR 160530R-P IC28 standard, this insert features an 85-degree included angle, a parallelogram shape, and a positive rake geometry that promotes clean chip evacuation and reduced cutting forces. The IC28 uncoated carbide grade is optimized for aluminum and other non-ferrous workpiece materials where a bright, uncoated surface finish is preferred. Two cutting edges per insert provide cost-effective tool life. Licensed machinists and CNC setup technicians typically specify this insert for high-speed aluminum milling applications.

This insert is suited for use in aluminum, copper, brass, and other non-ferrous metal machining operations in both production and job-shop environments. The right-hand cutting geometry and P-style chip breaker are selected for applications requiring controlled chip formation at higher feed rates. Compatible with HM90-16 series milling cutter bodies, this insert mounts via screw-clamping and is indexed when a cutting edge is worn. It conforms to ANSI and ISO 13399 standards, making it a direct specification-matched insert for tooling engineers sourcing replacements or building out new programs.

Key Features

• Solid carbide IC28 uncoated grade optimized for non-ferrous metal cutting
• Positive rake geometry reduces cutting forces and promotes chip flow
• P-style chip breaker for controlled chip formation at elevated feed rates
• Two cutting edges per insert for extended usable tool life
• Right-hand orientation with honed cutting edge style for improved edge integrity
• Conforms to ANSI and ISO 13399 standards for tooling interoperability

Compatibility

Compatible with HM90-16 series milling cutter bodies. Insert is secured by screw-clamping and is interchangeable within the HELIALU series tooling system per the ANSI code HM90 APCR 160530R-P IC28.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the tool body is secured in a vise or fixture before indexing or replacing inserts. Use the correct torque wrench and manufacturer-specified insert screw when clamping to avoid seat damage. Inspect the insert pocket and seating surface for debris or wear before seating a new insert.
