Iscar 5603287 Milling Insert IC28 Solid Carbide HM90

Product Description

The ISCAR 5603287 is a solid carbide milling insert designed for high-efficiency face and shoulder milling in non-ferrous metal applications. Carrying the ANSI designation HM90 APCR 160516R-P IC28, this insert features a parallelogram shape with an 85-degree included angle, a positive rake geometry, and a honed cutting edge for clean, consistent material removal. It operates in right-hand orientation and is held in the cutter body via a screw-clamp method. The IC28 uncoated (bright) grade is optimized for cutting non-ferrous metals such as aluminum and copper alloys. Licensed machinists and CNC tool setup technicians install these inserts in compatible HELIALU series milling cutter bodies.

This insert is suited for milling non-ferrous metals in both production machining and job-shop environments. It belongs to the HELIALU series and fits HM90-16 series cutter bodies. With a maximum depth of cut of 15.50 mm (0.6102 inches) and a cutting edge effective length of 0.6180 inches, it is well matched to medium-depth shoulder and face milling passes on aluminum and similar materials. The P chip breaker geometry promotes chip evacuation and helps maintain surface finish in high-feed non-ferrous applications.

Key Features

• IC28 uncoated solid carbide grade optimized for non-ferrous metal cutting (Material Grade C5/C6)
• Positive rake angle with honed cutting edge for reduced cutting forces and clean surface finish
• Right-hand parallelogram insert shape with 85-degree included angle for shoulder and face milling
• Maximum depth of cut of 15.50 mm (0.6102 inches) with a cutting edge effective length of 0.6180 inches
• Two cutting edges per insert for extended tool life before disposal
• Screw-clamp holding method for secure, repeatable seating in the cutter pocket

Compatibility

Designed for use in HM90-16 series HELIALU milling cutter bodies. ANSI code: HM90 APCR 160516R-P IC28. ISO code: HM90 APCR 160516R-P. Conforms to ANSI and ISO 13399 standards.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Always index or replace inserts with the machine spindle fully stopped and locked out per applicable safety procedures. Use the correct torx or hex key specified by the cutter body manufacturer when tightening the insert screw — do not overtighten, as this can crack the carbide insert or damage the pocket seat. Inspect the pocket seat and screw for wear or debris before seating a new insert.
