Iscar 5603553 Milling Insert IC28 Solid Carbide Uncoated

Product Description

The ISCAR 5603553 is a solid carbide milling insert carrying the manufacturer designation HM90 AXCR 150520R-P IC28. It is a single-sided, right-hand parallelogram insert with a bright uncoated finish, designed for use in the HELIALU series HM90-15 cutter platform. The insert features a positive rake geometry and a honed cutting edge for clean, efficient chip removal. With 2 cutting edges, a corner radius of 0.0787 inches, and a maximum depth of cut of 0.551 inches, it is engineered for high-performance milling in non-ferrous metal applications. Installation and tool changes are performed by licensed machinists and CNC operators in production machining environments.

This insert is intended for milling non-ferrous metals, including aluminum alloys and similar workpiece materials designated under ISO material code N. It seats into HM90-15 series cutter bodies and is secured via a screw-clamping method. The HELIALU platform is commonly used in high-speed face milling, shoulder milling, and helical interpolation operations in aerospace, automotive, and general metalworking production settings. The P chip breaker geometry supports controlled chip formation in these material types.

Installation Notes

Insert replacement is performed by a qualified machinist or CNC tooling technician. Always power down and lock out the machine spindle before changing inserts. Use the correct torque driver for the clamping screw to avoid seat damage — refer to the cutter body manufacturer documentation for the specified torque value. Inspect the cutter pocket and screw threads for debris or wear before seating a new insert.
