High Wear Resistance: Cermet end mills can work great for operations with high cutting speeds, light feeds, and typically dry cutting conditions,which is superior to traditional cemented carbide in many applications, especially at higher temperatures.
Excellent Surface Finish: Cermet tools have a low affinity for metal, which reduces the formation of a built-up edge (BUE) and leads to very smooth, shiny surface finishes.
Good Chemical Stability: Less interaction with the workpiece material, which minimizes adhesive wear.
Finishing Operations: They excel in finishing and semi-finishing of various materials, particularly in applications where surface quality and close tolerances are critical. (less suitable for heavy roughing or severely interrupted cuts.)
Conditions: Best used at high cutting speeds with light to medium feed rates and depths of cut, typically without coolant (dry cutting or compressed air) to avoid thermal shock.
