The process of obtaining key bittings by utilizing cut possibilities in four columns of the key bitting array directly pertains to the function of the key bitting array itself. The key bitting array serves as a systematic representation of various cuts that can be made on a key based on specific parameters, including depth and spacing. Each column typically corresponds to a specific position on the key, and by analyzing these columns, a locksmith is able to determine the appropriate cuts needed for a key to match the corresponding lock.

In this context, the key bitting array acts as a foundational tool that outlines all possible cut variations, allowing a locksmith to derive the necessary bittings accurately. This contrasts with other processes such as key duplication, which requires an existing key to create a copy, or key cutting, where the actual physical cuts are made based on the derived bittings. Thus, the bitting array is essential for visualizing and understanding the potential cuts that must be made to create an operative key.
