SDMT09T308-ZS OS5305 Milling Inserts

Description

The SDMT09T308-ZS OS5305 Milling Inserts are premium-grade carbide inserts developed for face milling, shoulder milling, and universal machining tasks. Engineered with the OS5305 grade and advanced CVD coating, these inserts offer outstanding wear resistance, high thermal stability, and long tool life, even under demanding cutting conditions. The fine-grain carbide substrate provides a strong foundation, ensuring toughness and reducing the risk of insert breakage during heavy-duty operations.

With the ZS chipbreaker geometry, these milling inserts ensure smooth cutting performance and efficient chip evacuation. This geometry helps to minimize vibration, improve surface finish, and maintain stable cutting forces. The design makes the SDMT09T308-ZS OS5305 Milling Inserts ideal for both roughing and semi-finishing operations across multiple material groups. They perform exceptionally well in steels (ISO P20–P40), stainless steels (ISO M20–M30), and cast irons (ISO K20–K30), covering a wide range of industrial applications.
