A small indentation made on metal prior to drilling is called a "pilot hole" or "center punch mark." This indentation helps to guide the drill bit, preventing it from wandering and ensuring accurate placement of the hole. It also reduces the risk of the drill bit slipping on the metal surface, leading to cleaner and more precise drilling results.
