RDMT10T3MO Milling Inserts

The RDMT10T3MO Milling Inserts are round indexable carbide inserts designed for a wide range of milling operations. Built from a fine-grain carbide substrate with a durable PVD coating, the RDMT10T3MO Milling Inserts provide excellent wear resistance, toughness, and reliability when machining steels, stainless steels, and cast irons. Featuring a round geometry, the RDMT10T3MO Milling Inserts deliver smooth cutting action, reduced cutting forces, and extended tool life, even in demanding applications.

These inserts are commonly used in high-feed milling cutters, face mills, and profile milling tools. Their round design allows for multiple cutting edges per insert, providing excellent cost efficiency. The positive rake geometry ensures smooth chip evacuation and consistent surface quality, making them suitable for both roughing and semi-finishing operations.

The RDMT series is widely applied in aerospace, automotive, and mold-making industries, where strong edge support and reliable performance are required.
