The CoroMill 419 from Sandvik Coromant is a five-edge, high-feed milling concept designed for for roughing to semi-finishing operations. The cutter is suitable for applications requiring high-feed face and profile milling, and for machining components that require long overhangs. It is said to improve productivity in applications requiring light cutting action and long tool life, particularly in difficult-to-machine materials such as stainless steel, hardened steel and titanium.
Inserts feature five cutting edges. Through-coolant on all cutters enables wet machining, with the option of compressed air cooling for improved chip evacuation in deep-cavity milling and helical interpolation. The cutter is available with a variety of insert grades and geometries in diameters ranging from 32 to 100 mm (1.25" to 4").

Toolholders with integrated cutting fluid delivery channels offer threaded, fixed-position nozzles that direct parallel streams of coolant to pre-defined positions at the top of the cutting tool.
