Consequently, the aim of this chapter is to provide an overview of how the game-changing approaches and technologies for advanced gun drilling can be explored and utilized. There is little literature available for the cutting mechanics and workpiece deformation, tool geometry, wear and failure mechanism, especially in the deep hole drilling process for superalloys. There are various fancy geometries, such as parabolic flute drills, that help you to go deeper, but they will also have a limit. Existing research in the advanced gun drilling technologies tends to focus on the choice of drilling parameters. Not only can these drills be used on deep hole drill machines, but also on machining centres or automatic lathes, for example. This chapter addresses the challenges of tackling these problems by employing game-changing approaches and technologies. Presently, it often incapacitates by low productivity, rapid tool wear, frequent tool breakages, and straightness deviation. Gun drilling is a process used to produce small-diameter holes at a high depth-to-diameter ratio, beyond what is capable using conventional tooling, especially for difficult-to-machine superalloys such as titanium, Inconel, Monel, etc.
