Iscar 5606941 Apkt 1003PDR-HM IC830 Milling Insert

Product Description

The ISCAR 5606941 is a solid carbide milling insert carrying the ANSI designation APKT 1003PDR-HM in manufacturer grade IC830. It belongs to the HELIMILL series and is designed for positive-rake face milling operations. The insert features a parallelogram shape with an 85-degree included angle, two cutting edges, and a right-hand cutting direction. The AlTiN plus TiN Sumotec PVD coating provides wear resistance and thermal protection during high-speed cuts. Corner radius is 0.0197 inches (0.50 mm). Licensed machinists and CNC operators working in job shop or production environments install this insert into compatible HM90-10 series cutter bodies.

This insert is suited for milling steel, stainless steel, superalloys, and titanium, covering ISO material groups P, M, and S. The HM chip breaker geometry and chamfered, honed cutting edge style manage chip formation across a range of feed rates and depths. Maximum depth of cut is 0.3940 inches (10.05 mm), making it appropriate for medium to semi-finish milling passes in demanding aerospace, energy, and general machining applications. It is held in the cutter body by a screw-type insert holding method.

Compatibility

Designed for use with ISCAR HELIMILL HM90-10 series cutter bodies that accept APKT 1003 size inserts. Cutter series compatibility is listed as HM90-10. Insert is screw-held and fits seats dimensioned for the 1003 insert size code.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC tooling technician. Disconnect and lock out the machine spindle before seating or replacing inserts. Use the correct torx or hex key as specified by the cutter body manufacturer when tightening the clamping screw - do not overtighten. Inspect the insert pocket and seating surfaces for chips or debris before mounting the insert to ensure proper seating and runout control.
