CoroMill 316 Ceramic Exchangeable Milling Heads

Sept. 26, 2023

The latest, brazed-ceramic CoroMill 316 offers a more productive method for roughing in ISO S materials than standard carbide milling cutters. With aerospace components manufactured from nickel-based alloys becoming increasingly prevalent, the demand for optimized cutting tools is growing. With this in mind, Sandvik Coromant has developed two innovative solutions ideal for shoulder and face milling of nickel alloy aero-engine parts.


The ceramic substrate of the latest CoroMill 316 allows for a different cutting process than traditional solid carbide tools. The unique S1KU grade is purpose-designed for the superior machining of nickel alloys and is supported by a negative geometry that offers a tough cutting edge. The 6-flute geometry delivers highly productive side milling operations, while the 4-flute geometry boosts face milling.


The CoroMill 316 is a perfect tool for difficult-to-reach applications or if you are looking for extra flexibility, thanks to the exchangeable head system. With the new, bigger head diameter available from D16-25 mm, it will be possible to reach high cutting speeds with conventional machining centers (n = 10000-18000 rpm).


Beyond shoulder and face milling, the end mills can also be used for pocket milling, helical interpolation, ramping, and slot milling.
