APMT 1604PDER-H2 OS5303 Carbide Milling Insert

The APMT 1604PDER-H2 OS5303 is a high-quality carbide milling insert designed for versatile face and shoulder milling applications. With its APMT geometry, the insert provides positive cutting action, low cutting forces, and efficient chip evacuation, making it suitable for a wide range of milling operations including slotting, ramping, and profiling.

Manufactured in OS5303 grade, this insert features a fine-grained carbide substrate with a PVD coating that offers a strong balance of wear resistance and toughness. It performs well on steels, stainless steels, and cast irons under light to medium cutting conditions. The H2 chipbreaker enhances stability and chip control, improving surface finish and extending tool life.

The 1604PDER designation corresponds to a 16 mm insert length, 4 mm thickness, and a positive geometry with 11° relief angle, making it compatible with a wide range of milling cutters. Widely used in automotive, mold-making, and general engineering, this insert delivers consistent and reliable performance.
