Life can be short for a drill. Machining materials such as Inconel, which is a group of superalloys made up primarily of nickel, chromium and iron, can be challenging. Inconel is part of a generation of superalloy materials used in gas turbines, heat exchangers, chemical reactors and rocket engines that can resist high temperatures, pressures and corrosion due to the hardening processes used to forge them. Because the act of working on them actually makes them stronger through plastic deformation, cutting or drilling into an Inconel alloy has to be carefully managed to prevent rapid wear and damage to the machine tools. Moreover, an efficient cooling during the machining process is very important to reduce the tool wear and increase the tool life.
