LOGU 030310ER-GM OS5305 Milling Inserts

The LOGU 030310ER-GM OS5305 Milling Inserts are high-performance carbide inserts developed for universal milling applications. With the OS5305 grade and a CVD coating, these inserts offer excellent wear resistance, thermal stability, and toughness. The fine-grain carbide substrate ensures strength and reduces the risk of edge chipping during demanding cutting conditions.

The GM chipbreaker geometry is designed to provide smooth cutting action, stable performance, and efficient chip evacuation. This makes the LOGU 030310ER-GM OS5305 Milling Inserts suitable for both roughing and semi-finishing operations. They are especially effective in steels (ISO P20–P40), stainless steels (ISO M20–M30), and cast irons (ISO K20–K30). The optimized geometry ensures reduced vibration, extended tool life, and improved surface finish, even under higher feed rates.

These inserts are commonly used in automotive, energy, and general machining industries where productivity and reliability are essential. With multiple cutting edges and a cost-efficient design, they provide excellent value for high-volume manufacturing environments.
