The term that describes a hole drilled into the edge of a door for lock installation is "Edge-Bore." This process involves creating a cylindrical hole in the vertical edge of the door to accommodate the lock mechanism itself, which is essential for proper installation and functioning of the lock. The edge-boring technique allows locksmiths to install various types of locks, including cylindrical and mortise locks, ensuring secure attachment and usability.

Other terms provided have different meanings. For instance, "Mortise" typically refers to a specific type of cut or recess made in a door or furniture piece to accept a mortise lock, encompassing both the hole and the lock body integration. The term "Recess" generally describes an indentation or hollow area created for various fixtures, while "Knob Screw" usually refers to the hardware used to attach a door knob to its mechanism, rather than a term for a drilled hole in the door. Understanding these distinctions aids in grasping proper locksmithing terminology and practices.
