Iscar 5603555 Milling Insert IC28 Solid Carbide Uncoated

Product Description

The ISCAR 5603555 is a solid carbide milling insert carrying the ANSI designation HM90 AXCR 150532R-P IC28. Designed for the HELIALU series cutter platform, this single-sided, right-hand parallelogram insert features a positive rake geometry and a honed cutting edge for clean, efficient material removal. The insert measures 0.7560 inches in length and 0.3940 inches in diameter inscribed circle, with a thickness of 0.1970 inches. Two cutting edges are available per insert. The bright, uncoated finish is suited to non-ferrous metal applications where coating adhesion or built-up edge would otherwise be a concern. It is screw-held and sized to the 150532 insert size code.

This insert is intended for milling non-ferrous metals, including aluminum alloys and other N-classification workpiece materials. It fits the HM90-15 cutter series and is compatible with HM90 toolholders designed for the 15 mm insert seat. Typical install scenarios include face milling, shoulder milling, and high-feed finishing passes on aluminum components in both production shop and job-shop environments. Installation requires a matching HM90-15 series cutter body with the appropriate screw and seat configuration. The insert carries a corner radius of 0.1260 inches (3.20 mm) and supports a maximum depth of cut of 0.5510 inches (14.00 mm).

Key Features

• Solid carbide IC28 grade optimized for non-ferrous metal cutting
• Positive rake, honed cutting edge reduces cutting forces on aluminum
• Corner radius of 0.1260 inches (3.20 mm) for controlled surface finish
• Maximum depth of cut of 0.5510 inches (14.00 mm)
• Two cutting edges per insert for extended tool life value
• Bright, uncoated finish prevents built-up edge on non-ferrous materials

Compatibility

Designed for use with HM90-15 series cutter bodies in the HELIALU milling platform. Conforms to ANSI and ISO 13399 standards under the designation HM90 AXCR 150532R-P IC28.

Installation Notes

Insert seating and screw torque should follow the cutter body manufacturer specifications for the HM90-15 series. Power down and lock out the machine spindle before changing inserts. Inspect the insert pocket and clamping screw for wear or damage before seating a new insert. This insert is intended for installation by qualified machinists or tooling technicians familiar with indexable milling tooling.
