APMT 1604PDER-H2 OS5102 Milling Inserts

The APMT 1604PDER-H2 OS5102 Milling Inserts are high-performance indexable carbide inserts designed for face milling and shoulder milling applications. Built with the OS5102 grade, these inserts feature a robust fine-grain carbide substrate combined with a durable PVD coating. This ensures excellent wear resistance, thermal stability, and toughness, making them ideal for machining steels, stainless steels, and cast irons.

The H2 chipbreaker geometry is engineered to deliver stable cutting action and smooth chip evacuation. With optimized cutting edges, the APMT 1604PDER-H2 OS5102 Milling Inserts reduce cutting forces, minimize vibration, and improve surface finish. Their design makes them suitable for both roughing and semi-finishing operations. These inserts are widely used in general engineering, automotive, mold-making, and energy industries where precision and reliability are essential.

Thanks to their positive rake angle and strong cutting edge, they provide excellent performance on low to medium power machines, ensuring consistent productivity. The OS5102 grade further enhances performance by maintaining edge sharpness while resisting heat and abrasion, even under continuous machining cycles.
