Key Features & Benefits
Wide Range of Products: The CoroMill® 390 series includes a variety of tool types, such as end mills, face mills, and long-edge cutters, covering diameters from 9.7 mm to 200 mm (0.375 to 8.000 inches) .
Light and Smooth Cutting: It employs indexable inserts with light-cutting geometries and high-performance grades, enabling secure, low-cutting force, and vibration-free machining.
Internal Cooling Design: Most CoroMill® 390 cutters feature an internal coolant supply, which helps improve chip evacuation and tool life.
