Iscar 5606644 Milling Insert IC28 Solid Carbide Uncoated

Product Description

The ISCAR 5606644 is a solid carbide milling insert designed for high-speed milling of non-ferrous metals. It carries the ANSI designation HSM90S APCR 140508R-P IC28 and belongs to ISCAR's HELIALU series. The insert features a parallelogram (APCR) shape with a positive rake geometry and a honed cutting edge, making it well-suited for aluminum and other non-ferrous workpiece materials. Key dimensional specs include a length of 0.984 inches, an inscribed circle of 0.492 inches, and a thickness of 0.238 inches. The IC28 grade is an uncoated solid carbide with a bright finish, delivering low friction and clean chip flow on non-ferrous cuts. Installation is performed by qualified machinists using the screw-holding method on compatible toolholders.

This insert is intended for use in milling operations on non-ferrous metals such as aluminum alloys. It is a right-hand insert with two cutting edges, a corner radius of 0.0315 inches (1/32 inch), a relief angle of 11 degrees, and a maximum depth of cut of 0.531 inches (10.01 mm). The chip breaker designation is P. It is compatible with the HSM90-14 cutter series and is suitable for both production and maintenance shop environments where high-speed aluminum milling is required.

Installation Notes

This insert is installed by a qualified machinist using the screw-holding method; ensure the toolholder pocket is clean and free of debris before seating the insert. Power down and de-energize the machine spindle before performing any insert change. Torque the clamping screw to the toolholder manufacturer's specification using the appropriate Torx or hex key. Inspect the insert seat and clamping hardware for wear at each change interval.
