Iscar 5601963 Milling Insert Apkt 100308PDTR-RM IC950

Product Description

The ISCAR 5601963 is a solid carbide milling insert carrying the ANSI designation APKT 100308PDTR-RM in manufacturer grade IC950. It belongs to the HELIMILL series and is designed for use in positive-rake face milling and shoulder milling applications. The insert features a TiAlN coating applied via PVD process, delivering heat resistance and extended tool life when cutting ferrous materials. Key dimensional specs include an inscribed circle of 0.2640 inches, a thickness of 0.1370 inches, and a corner radius of 0.0315 inches (1/32 inch). Two cutting edges are available per insert, and the right-hand orientation suits standard cutter rotation.

This insert is intended for productive metal removal in steel and cast iron applications, covering material grades C1, C2, C3, C5, and C6. The parallelogram insert shape (APKT style) with an 85-degree included angle and 11-degree relief angle is well suited to moderate-to-aggressive depth-of-cut passes. Maximum depth of cut reaches 0.3860 inches (8.00 mm), and the effective cutting edge length is 0.3900 inches. The RM chip breaker geometry promotes controlled chip flow and reduces cutting forces, making this insert a practical choice for production machining environments on CNC milling equipment.

Key Features

• IC950 grade solid carbide with TiAlN PVD coating for wear resistance in steel and cast iron
• HELIMILL / HM90-10 cutter series compatibility for direct OEM-style replacement
• RM chip breaker for controlled chip evacuation and reduced cutting forces
• Positive rake geometry with 11-degree relief angle minimizes cutting pressure
• Two usable cutting edges per insert maximizes cost-per-edge value
• Chamfered and honed cutting edge preparation for edge strength and smooth entry

Compatibility

Compatible with ISCAR HM90-10 cutter series (HELIMILL). Meets ANSI and ISO 13399 standards. Insert size code 100308 with ANSI designation APKT 100308PDTR-RM IC950.

Installation Notes

Installation is performed by a machinist or toolroom technician using a torx or hex key to seat the insert via the screw-holding method. Ensure the cutter body is clean and free of debris before seating the insert to achieve proper contact with the pocket seating surfaces. Power down and lock out the spindle before changing inserts. Inspect the insert pocket for wear or damage each time an insert is indexed or replaced.
