APMT 1104PDER-TT OS5305 Milling Inserts

The APMT 1104PDER-TT OS5305 Milling Inserts are high-performance indexable carbide inserts engineered for precise face and shoulder milling applications. Manufactured with the OS5305 grade, they feature a fine-grain carbide substrate and a CVD coating, which together provide excellent wear resistance, toughness, and thermal stability. These properties ensure long tool life and consistent machining quality, even in challenging cutting conditions.

The TT chipbreaker geometry is designed to deliver optimal chip evacuation and smooth cutting action. With stable cutting forces and reduced vibration, the APMT 1104PDER-TT OS5305 Milling Inserts achieve superior surface finishes and enhanced productivity. Their geometry makes them well-suited for both semi-finishing and roughing operations. These inserts are widely used across the automotive, mold-making, and general engineering industries.

Thanks to their positive rake angle, these milling inserts work effectively on both low and medium power machines, maintaining accuracy and efficiency. The OS5305 grade enhances performance in steels (ISO P20–P40), stainless steels (ISO M20–M30), and cast irons (ISO K20–K30), making them a versatile solution for universal milling.
